[@spacecruisers]

Yep, I did 1.5” lift on my sequoia and have run 32” and 33” tires. Been a great setup for me for the last 5 years. That combined with a skinner tire and as minimal offset as needed to keep it from rubbing the frame.

[@TobyCostaRica]

I’m only going to go as big as I can fit in the spare tire area. Makes no sense to have to get a hitch carrier to hassle with every time I open the rear lift gate

[@Toastert4co]

Couldn't agree more. I originally had the front end of my 2nd gen set at 3" lift w/ 33s, but had maybe 20% down travel and poor handling, always topping down when articulating. I lowered it down over an inch and it is far more capable on high/low speeds, but still has plenty of clearance for most trails I hit.

[@LexusGX460-OFF-ROAD]

*"Not lifted" since day 1 in our Lexus GX460. Explaining the reasoning to the masses has been an exercise in futility. The low COG combined with articulation simply keeps things planted. The lifted counterpart already thinks it's in a ditch and starts to get tippy rather than conforming and building confidence. Lastly, all Toyota engineers know what a "lift kit" is and how the ultimate goal of a balanced suspension geometry is the actual aim. Sadly stock suspension geometry is never really put to the test by many buyers because "lift kit" has been pre-programmed in their mind as some sort of offroading prerequisite... or more accurately: they do it for looks*

[@firesome11]

Yup I noticed how the Aussie channel overcame the struggle in the American trails

[@TXJ232]

I think most people are installing lift kits simply for the looks rather than functionality.

[@Jay-me7gw]

I'm all for not running lifts, especially huge ones. I ran my GX460 for 3 years with the stock suspension, skids and 285/70's and it was fine. But usually lifts consist of better shocks and springs than stock and improve many aspects of the vehicle besides just lifting it. Obviously, Lexus didn't tune the GX460 suspension tuning with pure offroad performance in mind. At the end of the day its used as a grocery getter by 99.9% of first owners and its a compromise of on road comfort and handling with a little offroad sprinkled in. Additionally, most aftermarket shocks for a GX460 are extended travel, meaning you can gain about 1" of additional droop travel. As long as you do not go for a huge amount of lift while doing this, the truck will be improved in most respects. I went to Bilstein 6112's with the heavy rate springs and kept it as low as possible. Eibach medium rate load leveling springs in the rear with Bilstein 5160's. The truck rode better in all conditions than the factory setup. Since I used the GX to tow, the heavier rate springs were a big improvement there, but still very compliant offroad.

[@gulu-cat]

Sadly you are restricting yourself to trails that only requires about 10 inch of ground clearance, which is common in CA where desert trails are usually not that demanding. There are tons of places in other states where stock height GX will immediately get destroyed.

[@TheFamilyCruiser250]

After taking my LC250 out on the trail, it got me thinking that I may not need a lift. It handled everything with ease and comfort. Made it out unscathed. FYI: I did gain 1" of ground clearance running "33s"(32.8in).

[@rotorhead5000]

Suspension droop is the un-sexy unsung hero in the offroad world. Jack the thing up, so you can put bigger tires on so it looks cool is unfortunately what way to many people are after vs actually performing well off road. Thanks for helping all of us data geeks get our numbers fix tinker!

[@dwaynE2099]

I am on my fifth IFS ute (truck) now and this one I've left bog stock in the suspension both ends. Although it helps being a Ranger Raptor, I had a previous gen RR prior to this one with a 2" lift both ends and cannot believe how much better the new standard one performs over the "improved" one (and the other three lifted vehicles I had prior)... I agree with your point about the specific type of offroading you do being important to understand before modifying, or leaving standard, your 4x4. In my case, standard height causes no problems as never work it on rocky trails where clearance is critical. This is one of the best produced videos I have seen on this topic!!!!

This is why I would love to see you review the Bronco and similar mods. The stock Bronco flexes very well (with disconnect of course) because of the decent wheel travel and specifically the down travel. Ability to fully stuff the jounce tire is also pretty good. So many common mods really kill the flex and give IFS a bad reputation.

[@trailrunnah8886]

Agree! I haven't seen it in person, but I watched a lot of Bronco videos and they do seem to be quite impressive for IFS. I'd also be curious to see an LE3 or LR4 Land Rover with air suspension, the way they work is as one wheel goes up, the air forces the opposite wheel down, so it functions almost like a solid axle.

[@Jay-me7gw]

@@trailrunnah8886 LX570 AHC does the same thing. Thats why an AHC LX can flex as well as a KDSS Land Cruiser stock vs stock.

[@Alan-bm3ni]

My friend took me on some mountain trails in Ouray, Colorado in a stock late 70's Jeep. There were lifted jeeps and fjs everywhere. I was completely blown away by what we could go up and down. I haven't modified my truck, and probably will only replace the shocks. I don't want to lift it and see no advantage to it. 4wd and a locker will get you very far. My gf test drive a bronco, with a factory lift kit and 35" tires. An extra $13k in value. It was stupid and didn't look good. A level bronco on 31-32" tires looks so much better and I'm sure performs at 95% of what a lifted one can, without the crappy on road experience.

[@Jay-me7gw]

@@Alan-bm3ni Old jeeps are a lot different than modern Toyota's though. The GX460 in this video comes with pretty atrocious clearance stock. Mine was stock with 33's on it and still was smacking running boards and bumpers and the trailer hitch on mild forest service roads. A Bronco has much better approach and departure angles but the 4 door version has a pretty long wheelbase so breakover could be a concern.

Info like this video help people prioritize or plan their upgrades.

[@austinarmagost2001]

Just tried this with some wood blocks and Rhino ramps on my stock '21 Chevy Colorado ZR2 (sway bar connected). I still was making good contact with the ground (front and rear) so I did not get full flex but I measured 4.5 in the front and 14.75 in the rear. This channel certainly has done a good job of showing some very valuable 4x4 suspension information. Keep them coming.

Update: I built some taller ramps and disconnected the sway bar. Front Flex: 6.5 in. Rear Flex: 15.25 in. Total: 21.75 in. I was at the end of my ramps still so there might even be a little more flex yet.

I simply removed my front sway bar from my 1st gen Sequoia, and when combined with the basic 2 inch lift the front articulation is pretty impressive for what it is.

Your videos have helped me get my Sequoia performing pretty well.

The smart people with GX's run 4Runner TRD Offroad wheels with +15mm offset that the 4Runner bro's sell to replace with Methods or SCS wheels. 🤣 We don't look that cool, but its cheap and functional and was able to fit 285/70's with minimal effort.

[@frankburch5104]

What an eye opener! I have a Westcott Designs Lexus GX 550 Preload Collar Lift Kit. I gained 2 1/2" of lift in the front and 3/4" in the back. It allows me to run Toyo Open Country AT III 35x12.5x17 tires on Method MR703 BeadGrip 17x8.5 wheels with a +35 offset. I was focused on improving the Approach & Departure angles and hadn't considered the flex ramifications. But it sure gives the 550 a great look!

[@Gazziza29]

Frank, please get rid of the spacer lift. Those things are garbage and don't listen to what Westcott says about it not affecting performance. With any type of spacer lift, performance will be worse in all aspects and they will ride like donkey shit. Just the facts.

[@Jay-me7gw]

@@Gazziza29 You do know that the factory Land Cruiser 200 series had the option of a 10mm spacer lift? The factory shocks still have plenty of uptravel available after the bump stops engage, so a small spacer only moves the shock down slightly but improves down travel and retains up travel without damage to shocks. Spacer lifts are not bad if you do it right and keep the shock protected by bump stops.

[@royj8549]

@@Jay-me7gw BIG difference between a 10mm spacer vs 60+mm. Pre-load spacers are the least desirable type, you're trading every mm of downtravel for every mm of lift. With strut spacers, at least some downtravel is retained, limited only by CV angle and upper control arm spring contact.

[@Jay-me7gw]

@@royj8549 the Westcott design spacer is not 60mm. They are like 10mm. I doubt anyone makes a 60mm spacer, that would lift the front like 5". Also, why would a pre-load spacer trade any travel. All its doing is compressing the spring a little more. The shock still has the same travel range. Yes it will be harder to fully compress, but thats how any lift works. And a preload spacer is the only way to help the suspension cope with heavier weight from winches, bumpers, skids, etc besides going to stiffer springs.

[@royj8549]

@@Jay-me7gw Usually, spacer height refers to effective height. Just like when we talk travel on a GX, we're not talking strut shaft travel, but effective wheel travel factoring in motion ratio. As shown by the GX460 in the video, factory spring rates are chosen so you're at bump stops under corner loading / articulation. You raise it 60mm (2.5"), and you won't use that extra bump travel, but you lose that in droop. A strut spacer maintains the bump / droop ratio within a couple % For weight compensation, sure. But not a 2.5" spacer. For GX460: 730 lb-in x 2 x .53 motion ratio = 774 lbs per inch of sag. How much weight you adding to the front end?

[@hansyang1697]

This also reminds me of the Nissan world, Especially for F-alpha platform. We do "Titan swap" on front suspension for wider track width (3in wider on each side) This helps with better total travel distance both up and down. And with longer CV axles, it helps to eliminate binding when reach to full droop.

[@toddmanning7844]

Such a great explanation of lift versus articulation! Helps me with my decision to NOT lift my KDSS-equipped 4Runner.

[@Jay-me7gw]

The one thing you miss by not lifting is extended travel shocks. Running extended travel shocks with minimal lift will be an improvement in terms of total articulation and still allow the truck to flex. Its when you start going 2.5, 3, or 3.5" of lift that things start to go sideways, but with the right shock and spring selection you could easily keep it to 1" lift.

[@toddmanning7844]

Thanks. Any recommendations on longer travel shocks?

The principle is what I learned about 15 years ago called a “low center of gravity” lift, or “LCG” Suspensions built for prerunners also use this principle in their builds. Huge 35 BFG Baja TA with plenty of limitation of uptravel, but huge amounts of downtravel at each wheel.

Hawaii boys with super lifted tacomas should watch this. Ridiculous here how these tacomas look.

[@seanmobley117]

Everything in this video is why I support the use of bracket lifts on properly built rigs. Everyone out there is chasing bigger tires, so they crank their pre-load and lose down-travel. All that pre-load requires more weight to overcome it and compress that spring, so they lose up-travel as well. All that and they have a set-up that looks cool, but has 5" of total travel and 35" tires. Since a bracket lift moves the wheel travel range downwards relative to the frame and body, it increases the room for bigger tires without sacrificing up-travel or down-travel. For example, my truck has a 7" BDS bracket lift, and I reduced the pre-load on the coils to achieve 5.5" of total suspension lift over factory. I have ~12" of total wheel travel on my IFS, with half of that being down-travel. And I run 40" tires without rubbing at full compression. I use the bigger tires for increased ground clearance, which helps especially on the rear solid axle. I hope that Kai can one day make a video detailing the pros and cons of a bracket lift on IFS trucks. I feel like it's information that everyone should know even if they're not in the market for a bracket lift.

I don't "wheel" per se but do take a '16 F150 out into the Mojave to a couple of my favorite "fishin' holes". We fish for tin cans, paper, AR500 alloy, that kind of thing. Meanwhile, I wanted a little more ground clearance for my rig. 2" is the generally accepted limit to "level" a stock truck; after that you can get into the problems Tinkerer's Adventure describes here, and from lack of "droop", or, suspension downtravel. And since I carry gear in the bed of the truck and sometimes hang a small trailer's tongue weight on the hitch receiver, I did not level the front of my truck to 2" but instead opted for 1.5" front lift via the Bilstein 6112 (also, Bilstein 5100s offer a similar, 5-postition spring saddle placement before assembly), knowing that I was preserving some downtravel by not topping out my lift height. The compromise, there, payed dividends, as Tinkerer's Adventure illustrates so well in this video. I recently ditched the zero-offset 17 X 8.5 wheels I was running in favor of a +25 Method 705, which when wearing a new, NARROWER tire (Toyo's ATIII 34 X 10.50 X R17LT D Load Range), has eliminated the rubbing issues at full steering lock that I was having when using the zero offset. And the new tire is also TALLER. Win/win. Great vid, as always.

When I was planning my lift on my '18 GX, I probably watched your IFS videos about this 20 times or so.

Ideally a 1" lift with 1" longer shocks/coilovers and a proper bracket diff drop kit is ideal setup. Then fit as big a tyre as can fit, regear and lockers, underbody protection and youll go almost anywhere. Here in Oz, the smart offroaders keep em as low as possible.

[@johnmcraven3598]

After watching the previous sway bar video, on my 3rd gen 4Runner, i: - took off the front sway bar, left rear in place - went from 700 lb front springs to 600 So far? Well, with no front sway, it's more ponderous on pavement, amplified by a switch to 'pizza cutter' sized KM3 tires. But off road? Way more balanced articulation. Previously I'd say that the body did about 90% of what the front wheels were doing, which isn't always a good thing. After? It's still somewhat front biased, but as a totally subjective guess, I'd call it 60/40. But I can really feel how the car is splitting the difference now, instead of making the rear axle do all the work. (1" body lift, 33" tires, 3" suspension lift, double locked, crawl box, manual trans '99) Love it, and it's not the sort of thing I would ever have thought up to try on my own. PS: I'm keeping the lift, I use the skid plates enough as is!

Looking forward to the gx550 full review. Im hoping you will cover things like axle and differential size and strength, etc! Also curious what a rear seat delete would ultimately look like!

[@rockie307]

Been off roading my entire life from atvs jeeps trucks sxs heavy machinery at work. In my experience ground clearance is king flex is important obviously but can be overcome to an extent with front and rear lockers. Most times I've been stuck I've been hung up on something either rocks deep ruts high centered. Also high clearance vehicles are better at river crossings especially swift water in Rockies like snow melt combined with storms flooding can happen quick. Snorkel doesn't help much if your washed down the river. When done right in most circumstances the higher vehicle will do better.

[@herisonblack1021]

Great video as always. You're definitly the no1 off-road vehicle expert on youtube.

[@boostbogan]

Your videos never miss, even when you personally attack me with facts 😂 Data mixed with some humour is always a winning combination, love your work!

[@Dav-S5658]

I enjoy this channel, but is there anyone who has not signed on with OnX Offroad? They have bought their way into every channel worth watching.

[@kennethpetronis2464]

Lifting is one aspect, lifting and increasing travel is the key.

[@GrandmasFolly]

This is a great channel. Severely underrated

[@ronito0793]

"Weird flex.... but OK" had me cracking up 😂

[@turdledive927]

Its great for flex, but where I am approach angle is very important. My jeep with a modest lift and larger tires does well. But I would bet the 550 would need a higher clearance bumper to hit these boulders

[@hevosenleukajoe]

Best truck hands down ive driven offroad had 400mm clearance, sisu sa-240.

[@Genghis_Khaan_]

Can you please do a review on the Nissan’s? Both the newer frontier and the older suv model. They’ve been picking up in sales since the Toyota recalls and I’d love to see newer makes on your channel.

[@rjm7168]

Not all lifts are dond at tgd expense of teavel. On my lift (not a toyota) the lower control arm is repositioned with add on crosmembers and a longer knuckle and modified upper A arm move compensate for the larger distance between upper and lower A arms.

[@SilverStarHeggisist]

Especially those done to solid axles, which more or less don't care how high they're lifted.

[@GXTOLX]

Would be interesting to get an lx600 in there. I'll bet it will beat all of them with flex. Your king of flex is obviously the lc80 series

[@gkcamden9050]

I love when I see one of your videos is uploaded because you drop so much knowledge on us.

[@ArkansasOffroad]

Amazing video man! Killed it as always.

[@TinkerersAdventure]

Thank you brotha!

[@wiciuwiciu2783]

Rollover!! I owned "Opel Frontera Sport B" (Isuzu Amigo based Vauxhall). It was considered crappy due to low lift and "only" LSD in rear differential. However it was a blast in mountains!!! 20° traverse was like nothing for that car! (Manufacturer claimed 40° but I didn't have the guts). Meanwhile my friend totaled "superior" Land Cruiser due to roll over 🤷

[@ryanlaing898]

Thanks Kai. Super informative. I'd always go back to watching your videos for reference whenever I'm unsure about lifting my '10 Hilux. Keep 'em videos coming!!!!

[@OtterSwims]

Wow, this is such a well madez informative video! Kudos to the excellent script writing and production!

[@BassRacerx]

this is a super cool video! so many people throw parts and upgrades at a truck and don't think of what the big picture will be or have any real goals for the vehicle's capabilities. It's just "upgrade this" "upgrade that". some parts you "upgrade" make the vehicle worse in some other way and it all adds up! The real question is "how much ground clearance is enough" how much ground clearence makes you feel comfortable to take on any / most trails?

[@chasedanger9734]

I have a 200 with long travel arms. I'm getting 13in of travel with stock AHC shocks. I added 1.25" strut spacers to change the range of motion (sacrificing compression for droop) making my wheel travel more usable. I did have to cut 2 in out the fender. It is a happy compromise to run 35s and not have to limit travel. Great videos keep it up

[@Jay-me7gw]

Thats awesome, 13" travel with AHC. I think I saw your thread on ih8mud.

[@chasedanger9734]

@@Jay-me7gw that is probably me. Haven't posted on there in years. I was only getting 12 then but when I cut my fenders I found more movement 🤙

[@marcotruitt19]

This has really turned my thinking process around about lifts. Thanks kai!

[@555byron]

Your channel is excellent. It has changed how I look at suspension setup. I am interested in RC crawlers as well. My most recent RC build was definitely inspired by your "lessons" about balance and making all four corners working more harmoniously. Without going into detail on the setup, the end result is a chassis that stays very level while going through it's articulation cycle It has the ability to "float" a tire across a gap without dropping the tire too fast, which keeps the chassis much more planted and less prone to rocking. I always look forward to your videos, as they are of the highest quality and are very intelligent. Keep up the good work.

[@Jay-me7gw]

Droop travel setups has been popular in the RC crawler world for a while. Some guys will run their RC's with the shocks basically bottomed out at normal ride height so the tires can only drop down. It lowers the center of gravity and also makes it so that, when the truck is on a side hill or climbing, the downhill shocks are already bottomed out and wont cause the truck to lean and roll. I had a TRX4 that I put extended shock towers on, and ran 120mm shocks at stock ride height. All the added shock length was in droop only and the thing was like a damn spider. The tires almost never left the ground ever.

[@rsKayiira]

Excellent video I wonder if you think Active Height control would be a benefit on the GX 550 in addition to the EKDSS. So that you can improve ground clearance when you need to

[@FearlessTrailhawk]

As a wheeler of full independent suspension vehicles, yes you are correct, and for most 'overlanders' and softroaders flex is more helpful than clearance. But for me and most people/places i wheel, clearance is more important as flex doesn't help you get un-turtled from large rocks. But you don't see many people talking about this though it seems common sense...stiffer suspension means less flex.

[@user-ds9fr5bj9s]

Fantastic content.I'd love to see a video about LC100/ LX470- how to lift it properly without loosing articulation.

[@spmyvr268]

Another masterpiece. Thanks you and greetings from British Columbia.

[@NerdOfftheRoad]

In Thailand, since factory rear locker come as standard in 4x4, we don't lift that high like in rigid axel era. Stock IFS with few lifted saves $$$ and capable enough on most terrain except rock climbing & water crossing. My 4x4 is 1.5" lifted on stock IFS and trim the fender to put 35" tire. Easy to drive and not easy to rollover. And on extreme 4x4 trip, I just left my sway bar at home.

[@freeidaho-videos]

Stock suspension and portals for the win.

[@zakikahl6904]

IFS is such a pain in the ass to get working right. Props to the guys who deal with it

[@Lamidnightsss]

I just bought ( my bank did) a 214 Runner TRD offroad. and I happen to think its the perfect height. All I want to change up is the wheels/tires. And maybe a few LED mods. other than that, It's perfect.
