I have a 2021 AT4 with a 3.0.  I'm looking to upgrade my UCAs but I can't decide on a particular brand or type.  I've looked at everything from BDS, Zone, Cognito, Readylift, etc. I have Bilstein 5100s coming in to go all around and plan on running the fronts at full 1.1" height.  I'm not looking to raise anymore than that or I'd just go 4" kit. 

I talked myself out of a level kit after hearing about all the ball joint and CV issues.  I plan to run at least 34s when my tires wear out. ( I run 295/55R20s right now)   It's my daily driver and don't plan on plowing thru mud holes on the regular but I still need it to perform on some back roads from time to time.

I have the Rough Country upper control arms with Fox 2.0 coilvers (1" over stock) on my Trail Boss.  They're OE type design, affordable, high quality and correct the ball joint angle.  For no more lift than you're doing I think they fit the bill.

Curious how you like the Fox shox, and if you have a link to where to buy them?

They're nice, it's Fox's shocks and Eibach springs.  Gave me 1" over stock out of the box and stock like ride.  I bought them from a no-name vendor on Ebay.

‘21 Sierra AT4 3.0L dmax
Bilstein 5100 front and rear, 1.1” setting

Cognito UCA, round

Stock 18” wheels

Stock Duratrac 275/65r18 tires

 

Still has some rake (I haven’t measured it though), I’d prefer it be more level but I don’t want to mess with any spacers so I guess it is what it is. 
 

After these tires are done I want to try 285/70r18, I’m just concerned about the UCA and tire clearance. I like the stock wheels just fine so I don’t really want to change them.

Nice setup.  How many miles do you have on it so far?  Are the ball joints replaceable on those?

that’s about the setup I’m looking for. I think I’m gonna try to go 285/65R20s or 35x11.50s depending on if I stick with Nitto RGs like I have now.

Thank you.  About 10k miles, yes they're replaceable.

Running the Bilstein 6112 at 1.2” with the Readylift UCA. Works great.

Exactly what I want to do.  I'm going to have to buy the damn leveling kit to get the UCAs though since they don't sell them separately.  My tires have about 1/2" clearance to the factory arms....I'm fairly certain I'll have to run a small spacer on the front to clear.

 

What is your wheel/tire setup?

I had the RL level kit already so I kept the UCAs.

How do you like the Kings? I was lookin at them from accutune with those same arms! Delta joints seem like best option for a street driven truck that will see weather etc.

Love em! I got my set from Filthy Motorsports w/ the Deaver Leaf Springs. The Delta Joints have been great as well. They’ll get the job done till I upgrade to a long travel setup. Accutune are awesome at what they do as well, you won’t be disappointed!

Nice! No plan for long travel here, reading about not lifting more than 2.5” concerns me because my truck is an AT4 and came with rough country 2” level kit. So 4” over normal... I’d want the same height

      OCI, not when but why?

      By Chuck FB · Posted

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.

      Tranmission stays in Low

      get a good code reader, and find out what problems the truck has noticed by reading codes. cheap ones can only get basic engine codes, you may want to get one that can get codes from all the computers in your truck.

      This is sort of my point, salvage yards aren't overflowing with all these 'poorly' maintained trucks - excellent/good/servicable condition otherwise, salvaged only as a result of a bad engine from poor oil change regiment.    In my area, there are no 2007 to newer gm trucks/suvs in any salvage yards. A few are in the 'recyclers' with very obvious reasons for being there - wrecked.

      Stabilitrak conversion to Z71

      By asilverblazer · Posted

      Stabilitrack was a stability control, traction control system, that functioned independently from the transfer case.   Z-71 has nothing to do with the transfer case or differential.   If it does have an AWD system, my memory recalls this being specific to the Denali trim, converting won't be as simple as swapping out mechanical parts like differentials and transfer cases. It will require reprogramming at a minimum. Long story short, not likely worth it.   Pulling a fuse, may disable the AWD system, it might also prevent any other transfer case functions.   However, the AWD case was generally based on the same transfer case you refer to in the 2006 Suburban. If it still has a 4-High and 4-Low where the transfer case locks and splits power 50-50 front to rear, what are you gaining by changing anything? A true-rear wheel drive only, what good will that serve? Not enough to go through the trouble of changing out all the parts.    Generally, all the factory systems will handle a 33" tire and re-gearing. Probably a 35" tire too, if you aren't driving like a caveman. If 35" tires are in the plan...   If you do plan on driving like a caveman or are fully committed to 35" tires, an entire re-think of the build is probably in order. Starting with square one, an IFS front end isn't going to be the best starting point for 35's and caveman driving.

      Oil Consumption

      By PunchT37 · Posted

      1/2 qt over full ain`t gonna hurt $h!t. Most times, a whole qt won`t either. Most have windage trays now. As long as the crank isn`t slapping itself in the oil, it`s not the end of the world.   We used to overfill 1 qt at the track, at race time. Better to have it over full than having the pan sucked dry at 6500 rpm`s.
