Which UCA is Best for YOU? Toyota Aftermarket UCA Part 2

[@christopherwilson9140]

The xAxis joint is completely insulated from the steel by rubber. This gives it better NVH than a rod end. I know this because I had to replace one, the process involved drilling out the rubber yo remove the metal portion of the joint.

[@TinkerersAdventure]

Ah you’re correct. Looks like SPC has a UCA specific x-axis bushing, which is the generic x-axis joint wrapped in rubber. Hmmm this is even better. How long did yours last? Or why did you have to replace them?

[@DRUMZ4LIFE82]

25,000 miles, they’re no good

[@christopherwilson9140]

@@TinkerersAdventure I did the thing where you buy mevotec supreme and SPC parts come in the box. One of the joints went bad really fast and at the time I could not get them warrantied because they were out of stock. So I found the kit to replace them. Other than that the rest have been fine for about 20k miles.

I love that the two most popular brands for UCAs ( Icons/ total chaos) are not even mentioned, such piles... if you want rubber ducky noises everywhere you go, get total chaos. if you want never ending servicing ( and failures) get Icon. these videos are worth a LOT More subs and likes, amazing work, thank you!

[@ceeIoc]

Are the icon tubular with delta joints no good?

[@drsus0]

@@ceeIoc the icons are good if you're willing to do the servicing to the delta joint ... and most say they will do this but end up leaving them on til they crap out THEN servicing them, and by then you usually need new ones you can go on any forum and type "dealt joint worn" and a bunch of " I need new ones already!?" or " its only been 6 months and they already make noises" etc. if you stay on top of them, they will last and stay quiet, but as I said, most people don't.

[@ceeIoc]

@@drsus0 gotcha. I really just want a set it and forget it uca. It seems spc is the best but maybe I don’t need that much adjustability on a 2.5 inch lift. Have you heard of Freedom UCA’s? They have good reviews on a Amazon.

[@drsus0]

@@ceeIoc the non delta icon is a good one. the SPC are great ones you set them up. I hear the Accutune ones are also good. have not heard of the freedom and I wouldn't pout too much weight behind amazon reviews. id go on as many forums related to your truck and search for freedom UCA, if no results, ask. you want real user input, not a review form some guy that installed them drove around the block and gave it 5 stars.

I have the Icon Tubular with delta joint. Super happy with them after 4 years of abuse. Recommended them to my friend and he’s happy with them as well.

Make sure to check your delta joints. They will start to rock back/forth and simulate the feelling of a bad wheel bearing. Not cheap either. I'm replacing both UCA for half the price and work of replacing the delta joints

Keep up the great comparison and demonstration vids! 👍

[@GrizzlyPath]

Great comparison and rundown! I went with Ironman UCAs because I valued them being basically maintenance free and closer to OEM. I can swap ball joints out and get new bushings without having to go with expensive alternatives. Additionally, I’ve found a lot of the spherical joints to be noisier, even when greased up regularly. Obviously going to depend on use case, but for me a more OEM spec worked great.

[@TinkerersAdventure]

Agree, unless for actual racing, I always prefer everything close to OEM.

Funny how there’s always a toyota lean on their 4wds. I had an hdj80 with the same driver side lean and 2 fortuners 2015 and 2020 with the lean as well. Only explanation i could think was the fortuners were designed for a majority RHD market so fuel tank sat on left to balance the driver side rhd but in making LHD market units it causes all the weight to sit left side.

Ive had SPCs on my tundra and now SPCs on my tacoma and they have both been flawless. I grease the UBJs every other oil change and they remain silent.

[@ejshelby5460]

the comment about clearance and reservoir hose addresses exactly what I've been dying to know. I ran the old man emu BP51 on the 4runner front, but kept the stock UCA, as I set the preload to be very low. However, somehow it still gave me a 3" lift!! The lift aside, I am really concerned that the hose is tightly tuck between the shock body/collar and the UCA, I feel the down travel of the UCA will soon destroy the hose.

[@dawgrules1]

Also, spherical UBJs squeak LOUD and require constant attention once they have some miles on em! Good info, thx !

[@Tranfamilies]

that would be interesting video. I thought I need at least fr sb, but after remove them all and with IM FCP and heavy spring (my rig is heavy), it handles very well offroad. Onroad it is not at all bad as many have said it would. I bought the fr sb to install but now decide to go without fr/rr sb.. Dampening of suspension and correct pairing of spring definitely help. Love to hear more from Jake analysis

I really like your videos. Lots of information to digest so we can make the best choice to modify our suspension. Could you please include JBA Uca in your video comparison. The company says it has a 99 degree of articulation at the ball join due to their design and channel for grease on the bushings. I am having a hard time de siding which UCA to get and now I am trying to figure out what is the better lift high. I used to think the a 3" lift was better for clearance but I am not sure that is the way to go unless you are getting a long travel set up like the Marlin Crawler which very expensive giving everything it needs to be modified. For me budget is very important since I cannot afford to expend a lot of money on the suspension but I want something that is reliable and does not break the bank. Thanks again for your videos.

It's a pretty impressive design. He did had to refab the front of the wheel well (under where the battery is mounted), which is probably more difficult to do. My dirtking long travel pushes the tire forward 1/2", I'm running 315/70R17. I'm already rubbing the front of the wheel well near full compression and steering. So I don't think "no need for BMC" means "less work" as many thought. Nevertheless, this kit has many unique benefits.

[@alexs825]

In another video you should explain as to why regearging doesn’t change MPGs in any significant amount. People keep repeating these myths without any understanding of the engineering behind it

[@stonewp]

The result depends on the overall combination of engine power, transmission gear ratios, diff gear ratio, and tire size. Changing the diff gearing can make a significant impact on MPG and drivability.

[@Rob_Basich]

Clearly you don't understand what you're talking about.

[@joeforster2255]

obviously it can affect your mileage greatly, cruising at a higher or lower rpm will directly affect your mileage.

[@michaelbaylis1631]

as an Engineer, I can tell you regearing absolutely effects MPG. Consider sitting in overdrive, at 70MPH. One gearing compared another, might result in 200rpm less, keeping the vehicle in a better torque zone at lower engine speeds. Thus, using less fuel. If you think gearing doesn't make a difference, next time don't shift to 6th gear, sit in 5th and rev it higher and see what that does to your MPG. Often when increasing tyre size, the overdrive gear is no longer achievable without excessive throttle and fuel input. Regearing will shift the rpm and torque to the correct ratio, allowing overdrive to be available at a low throttle input at highway speeds.

[@NoLies17]

Unless this is a troll post, it's possible that they are referring to regearing FOR taller tires (only). If you're matching lower gears with taller tires they can cancel each other out. Obviously, my post isn't aimed at regearing for specific offroad needs like rock crawling where you have larger tires and you're gearing down past that to also have a better crawl ratio. If you're mall crawling with larger tires, you're just gearing down to get back to a stock final drive ratio with similar mpg, so long as you didn't put mud terrains on. ;)
