There is a huge thread on Bilstein 5100's a couple pages in. Your UCA's are good to go up to 3.5" of lift. The Trail Boss and Non Trail Boss use the same UCA's. You can level a Trail Boss (+1.5") with no problems, hence the 3.5" lift.

Completely wrong, the stock UCA are only good to 2 inches anything more your going to greatly reduce the life on the ball joints and CV axle joints being at such a bad angle. Ball joints and CV axles will be binding and not designed to operate at those extreme 3.5" angles. He won't be able to get the frontend aligned to spec also.

Would Bilstein 5100 shock's require me to replace my uca or can keep the ome provided with vehicle?

 

2" max anymore you're looking for trouble.

Then how do Trail Boss owners level their trucks? Trail Boss already uses different CV axles, but the same UCA'S.

 

The only thing I forgot to mention is if you go more than 2" you need to install the Trail Boss CV's.

Most go with removing the rear block on the axle to level the Trailboss. The Trailboss does have longer front CV axles for the 2" lift that they come from the factory and that is max that can be done in the front is 2" to keep it in spec anything higher than that your binding the ball joints and the angles of the CV axles are to great. If going higher then 2" to like 3.5 you need new UCA's and a front diff drop to keep it all in spec. Blowing a ball joint at highway or any speed is not pretty, I have seen the after effects of it happening.

1.5" TB Leveling kit without changing the UCA's. That's 3.5" of total lift using the same UCA's.

HAHAHA just because it says it can be done DOES NOT mean it is good on your frontend evidently you have never done lift kits I have also don't go telling people they are good to do it and there not. People come looking for correct info and anybody will tell you a 3.5 lift on a stock IFS frontend is asking for trouble. Iam done here.

So, we should listen to you instead of Rough Country, who is literally in the business of lift kits. Ok, got it.

 

Guys level out there TB's all the time without changing the UCA's and don't have any problems. GM anticipated this and built enough geometry into the UCA's to handle it. Just look under a stock TB and look how the control arms are sitting, just about level, no extreme angles. These are a new generation of chassis and suspension, it's not the old school stuff where 2" would really be pushing the limits.

Rough Country has a long history of cheap lifts with sketchy geometry and build quality. Decades of it. 
Don’t use Rough Country as a good example for lift kits.

Beat me to it.  RC is low quality and cheap garbage.  It's like comparing Temu to Amazon.

It really doesn't matter which company or builder I referenced or used as for example, because someone would show up to tell use they don't what they are doing and all their products suck. Evidently, I was right.

Go take a look at ReadyLift's website.  Better quality products, and they replace the uca in their 1.75" leveling kit and 2" lift kit for Trail Boss/AT4.

To be fair RC lift kits are junk, been well documented on this website for years now. And heck i don't even think a month ago we had someone on here posting pictures of their front cv's slinging grease all over the underside of their truck because they also thought that all of these lift kit manufactures cared about angle integrity of the cv axles.

 

You will always get what you pay for imo, especially with something like a kit that alters OEM engineered specs!

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
