he likes to tighten stuff fully tight, with an impact before starting the other nuts/bolts. Also didn't start the nuts by hand before hitting them with the 3/8 impact on top of the strut. Great video with a few minor things I would do differntly

[@predwin87]

I did this kit on my 2010 chevy silverado but i felt the rear was an 1" lower so I decided to go with 3" rear block instead of 2" to level the truck

[@predwin87]

Thank you for the great installation instructions video step by step, doing mines today 🎉

What is the offset in the wheels and tire size you put in that truck?

[@NSWvet83]

Dude, it must be slightly different with the torque of the truck but I had problems left and right with a crew cab. Exp: You needed pry the stability bar up, I needed to go down, also you did t talk about how the strut no longer lines up.....that was a huge hassle!

[@predwin87]

I did this lift kit i installe a 2-4” control arm and now am having problems to get the truck alignment correct

[@predwin87]

I have a question..i put this lift kit. On my truck, after you install this kit did you had any problems with the truck Alignment?

[@shupster369]

Curious how come you didn’t replace the UCA, aren’t those the steak stamped uca?

[@drew5992]

How long are the factory bolts that go into the bottom of the strut?

[@C.I.A_Unclassified]

Yea I’m pretty sure spring compressors are necessary when connecting the upper control arm back. My truck just lifts right off the jackstand

[@bobbykoffel1442]

What wheels ans tires are these the 33” setup? Thanks

[@drew5992]

No shims or diff drop? Any rake with this kit?

[@williamwilson3008]

overall great leveling kit, but to include all of the other stock manufacturing parts for the front end, highly recommended to replace tie rods, cv's, A arms, Idler arms, spacers or a drop bracket for the dif, wheel bearings. and like I said, no negative remarks towards this kit, you get what you pay for. for me I've been a plain old stock truck guy myself with no upgrades or aftermarket parts and after upgrading to a newer truck I figured I'd try this kit, does make the truck look a whole lot better than having a racked look.

[@k1m3zz]

hey i'm a new truck owner and i was thinking about purchasing this for my f150. how much would it affect my ride quality if i did not replace all of the parts you listed?

[@WilliamWilson-pw5oz]

​@k1m3zz do you plan on upgrading to a bigger tire size?

[@k1m3zz]

@@WilliamWilson-pw5oz yes my stocks are 31s i’m thinking about getting 33s. i feel like 35s would look a little too big

[@WilliamWilson-pw5oz]

@k1m3zz yeah I went with 33s. No issues either... if you were to go bigger then 33s, might have to tweak the fenders and plastics for them not to rub.

[@Adman-p4j]

I believe this will take it from a 2.5" rake to a 1.5" rake. I'm at 0.5" rake right now (2" level on the front) and I still think it doesn't look quite right. I feel like 5.5" front and 3" back would be perfect.

[@treyharrell557]

Just to clarify would this also work on 2wd version of this truck

[@N.C.S.W.I.C]

Always keep in mind once everything is loose that the Left Nut will tend to hang slightly lower than the Right. 👍

[@pandora655]

My left nut definitely hangs lower.

[@fernandobarboza6857]

Perfect Thanks. Good video

[@AmericanTrucksChevyGMC]

Thanks for watching! -Zach

Will this work on a 2009 gmc single cab long box 2wd

[@javierherrera1101]

I have a question what was the rims size?

[@vincemiracle103]

how will affect the ride of my truck ? I have a 2018 Silverado. will I need to replace upper control arms ?

[@AdamLeclair-uf5to]

Did you have to replace upper control arms? I need to know if I should too?

[@SkipperBath]

Great video, thank you!

[@JOSHUA2814484920]

What’s the highest kit recommended on 2wd 2018 Silverado if trying to keep original suspension

[@cfmotonut3090]

According to Google max of 3 inches in the front.

[@bassstudiosx9780]

I’m having major issues with my lower control arm not making it up to the ball joint. Any tips?

[@AmericanTrucksChevyGMC]

Because of the 3-Inches in the front it is a pretty hard angle so we do recommend upper control arms that are angled correctly for that extra height. If you're still having trouble, we recommend trying to loosen up the control arms or even putting the vehicle down with and jacking it up with a floor jack to meet the two.

[@ShaneandShayna]

I have 33s on my 17 real tree stock… no issues at all

[@mrmidnight32]

I don’t get it, I run a 33” on a 2” lift. A 3 or 4 should be able to fit 35’s.

[@jacobward9151]

I have a question i have this level but i have a 2in rake in the front why is this?

[@loganlucero6833]

I bought a leveling kit for my silverado and it raised the front 3inches. Will i need to take it OFF in order to fit this 3inch leveling kit?

[@JoseCruz-hl3fl]

It didn't work on my 2012 silverado 1500 lt 4x4 looks like i have to buy longer upper control arms

[@frasermacmannis614]

what are the drawbacks? more strain on the drivetrain?

[@Adman-p4j]

the control arms go out of angle a bit but it's not enough to cause much difference. You will notice a change in how your truck goes over bumps (rougher ride). Fuel economy drops the higher you lift it also.

[@jeneltamorada8882]

After this mod. Would you be needing to do an alignment? Just wanted to confirm that. Thanks.

[@AmericanTrucksChevyGMC]

We always recommend getting an alignment after modifying your suspension! -Zach

[@dean_cain]

I ordered a simple front leveling kit and about 2 months after install I noticed heavy camber wear even though it drove fine. Don’t make the $600 dollar mistake I did and get an alignment!

[@Herbymac0811]

Will I need upgraded shocks to? And will there be any control arm issues or ball joint issues?????

[@masonseets1682]

Dont be afraid to try multiple tire sizes on your truck. The sizes varies a little manufacturer to manufacturer. I am running 35s on my 2018 Silverado that I leveled with the 3 inch kit

[@zo6freak]

Awesome. What tire are you running and how did you get them to fit?

[@masonseets1682]

@@zo6freak Hercules all terian. I did nothing. They fit with the factory wheels

[@Adman-p4j]

No rubbing or scrubbing at full turn?

[@masonseets1682]

@@Adman-p4j with the factory wheels yes I had yes. Wheels rubbed on the control arms. Tires clear just fine even when offroading

[@mrmidnight32]

I was going to say I’m on a 2015 with a 2” level kit and run 33” KO’s’s no issue. A 3.5” should fit 35’s with no issue. Maybe a tiny cut.

[@predwin87]

So with this 3” lift do u need to upgrade the upper control arm or u can leave the stock one on there

[@GearScar]

Yes upgrade it, there is a upper control arm specifically for lifting these trucks

[@predwin87]

@@GearScar ok, i did upgrade it, 2-4" lift control arm, i took my truck to tire corral n they mess up my alignment,

[@GearScar]

@@predwin87 ok, you need 1 more thing if you haven’t already, get a front differential drop kit, it’s 4 little spacers and longer bolts to lower the front differential, doing this puts your cv axles at a nicer angle to reduce the lift kit stress on them and prolong their life

[@christiankrejci9233]

Looks like the right amount of height I would like to add to my '14, however, my question is would I need longer rear shocks in order to compensate for the 2" lift blocks? Any insight would be appreciated.

[@coltono3223]

If you don't get longer ones they will most likely go out down the road

[@gaviin1033]

Does this put much strain on cv's? Would you need to get some dif drop brackets as well?

[@williamwilson3008]

so, I got the kit, and yes, I'm needing to look into drop brackets or spacers for the dif as well, because I just had my passenger cv go out. and yes, I'm a little late to the feedback because at the time of me getting the leveling kit, I thought of the dif, but was wanting to see how the overall performance was with just the leveling kit.

[@jmkx81]

Not late for me, anything else you would upgrade? I’ve got a 2011 Silverado that a new motor ready for this upgrade. Think of doing Monroe struts and springs. I do remodeling and pull a trailer often.

[@joelthomas4294]

I thought you had to change the control arms to keep stress off the ball joints with a 2.5 to 3 inch lift??

[@AmericanTrucksChevyGMC]

If you have room in your budget, a set of aftermarket upper control arms would go a long way in helping your ride comfort and suspension angles for sure! -Zach

[@user-nb7be4mn2x]

Your supposed to, but it will drive

[@mikesports9517]

Would I have to put on a longer driveshaft?

[@AmericanTrucksChevyGMC]

It's not required for this lift.

[@Mike_Y.]

I have a 2018, watch out for those weak upper and lower control arms

[@2a4me96]

You talking about stock? Because they say you should replace upper arms if purchasing this level kit

[@predwin87]

I think 3" front n 3" lift rear block will level the truck just right, 2" rear block still has a rake not my style the rake

[@up9709]

What’s the diameter of the wheel ? I checked the description and I didn’t see anything thank you

[@HoleCleaner]

9:46 look at the right bolt and see how loose it was, hopefully it was tightened again.

[@Eric-yc2hz]

What’s better a 3 inch lift or 4 inch lift ?

[@AmericanTrucksChevyGMC]

Depends on how high you want to go and how big of tires you want! -Zach

[@MD-xw3gd]

Tools needed . Impact ✔️ Bigger impact ✔️ Crescent wrench ✔️ Bigger cresent wrench✔️ Hammer

[@cfmotonut3090]

Technically you are not rasing the rear of the truck 2 inches at all, it will only be 3/4 of an inch! The stock block is already 1.25in, so you have to remove the stock block, and replace it with a 2 inch block, therefore only rasing the truck 3/4 of an inch.

[@ericvazquez7623]

It’s a 3inch rear block. The logic he explained was the stock block already sits 1” so replacing the stick block with the 3” block makes for a total 2” rear lift. He measures the block in the video

[@Cryptid_Slayer_]

I can tell you right now this can’t fit a 32.8/11.2r17. It rubs the back of the wheel well.

[@IlhamJr-xp5wy]

Wrong I fit 35’s with ease with stock blocks

[@edensmith4809]

I’m just having trouble with upper control arm ball joint can’t get mine off

I have a 2007 Chevy avalanche and I'm planning on installing a 3 inch lift up front using (2inch extended struts from freedom off-road) and a 1 inch under strut spacer and 2 inch rear spring spacers. Along with aftermarket A arms. Will I need to do anything else besides new a arms up front?

[@MudGoose]

When y'all gonna lower a truck?

[@AmericanTrucksChevyGMC]

Once we get a customer truck in here to install one! The trouble with most lowering kits is that permanent modification is required and we can't install them on our fleet vehicles. As soon as we get one, we'll get it uploaded! -Zach

[@604cuinkillah]

Why would anyone lower a truck?😅😅

[@ImBrownbo]

9:48 so we skipping the other side loosing up LOL okay

[@christophernaughtin3002]

now align it.

Always after installing suspension! -Zach

[@OscyJack-]

For God's sake, don't install this without some cheap UCAs with corrected balljoint angle
