Hi guys, a little background... I have a 2021 AT4 that I did a 1” level on but I am now worried about upper ball joint failure so I’m looking at replacing the upper control arms. The price point is nearly the same for the Rough Country, Cognito, and ReadyLift arms but would like some input please. 
 

Rough Country- Aluminum, rubber bushings, they say the ball joints are replaceable but I haven’t found them, greaseable ball joint. . I like the look of them too. 
 

Cognito-poly bushings( squeak down the road?), bolt in Moog ball joint that I’ve found for $60,  greaseable bushings, non greaseable ball joint. 
 

ReadyLift- very similar to Cognito but with rubber bushings, greaseable ball joint, also says replaceable ball joint but haven’t found it. 
 

I’m also considering not worrying as much about it because comparing my ball joint angle to a friend’s stock TrailBoss they look the same. However, the primary purpose of this truck will be to tow my track car and a ball joint failure then could potentially destroy both my vehicles. The other reason I’m concerned is another friend with 2020 GMC (non AT4) just had a ball joint fail and he’s at 3” of lift which is what I’m currently at.  I just bought 1/2” leveling kit and for now I’m just going to drop it down a bit until I get the UCA’s. Right now I’m leaning towards ReadyLift I think but would like to hear what others are running. Thanks

I've been going back and forth between Zone Offroad and Ready Lift for my 1500 AT4. Leaning towards Zones but definitely interested is this thread.

If you are looking for a deal on UCAs, I found these discontinued Rough Country UCAs on eBay for $120. Not sure of the quality though.

Hmmm... I wonder what the story is with them and why they were discontinued in the first place. I’m going to have to call Rough Country. Thanks for the link!!

I'll be getting the ready lift as in Canada it's the cheapest I can get. I'm not going to be driving my truck like a Raptor or TRX so I'm confident they will be fine, all are better than stock at least.

I have the ReadyLift arms and they are very solid, only weak point I see is maybe the ball joint but it’s fully greasable. I had a set of Cognito arms on my old truck and those were indestructible however I didn’t feel like dropping that much for UCAs as I bought the RL SST kit.

The Cognito UCA I’m looking at are the same price as the RC arms and cheaper than the RL kit. What don’t you like about the RL ball joint nd have you found an available replacement ball joint for them?

Well the kit is more than just new UCAs so yeah makes sense why it’s more. I think all RC stuff is garbage. 

They look a cheaper ball joint that’s all, not the cheapest but just not the highest quality.

I called Rough Country about these today. They discontinued the kit these came with and chose to go with the Al arms when they came out with a new kit. Otherwise there is no difference, they even use the same ball joint which is good although you can only get the ball joint from them (so they said).  I'm still leaning towards the ReadyLift arms but $120 is sure tempting. I want to speak to ReadyLift and see what the ball joint is in them and if it is readily available just in case 5 years from now I need to replace it.

I had the cognitos on my 17, no problems, the bushings were quiet and lube'able.  The ball joints were easy to change (4 bolts) and each had a zerk fitting.

How long/ many miles have you had the RL arms on for?

I had RL UCA's on my 2019 AT4 for 10,000 miles before I traded it in for a 2020 and had no issues.  Only issue is they are bigger in circumferance - so they are a lot closer to tire that stock UCA with same wheels.  Here are some photos - so if you want bigger tires, you may need ot change out wheels as well.   the photos are of the UCA with stock 275/65/18 Duratracs on Method 18"x9" NV wheels with a 18mm offset - the stock 18" AT4 wheel is 26mm.

Thanks Supercup, I have 0 offset wheels so clearance shouldn’t be an issue. I like both the RL and Cognito, I like that the Cognito ball joint is readily available. They gave me the MOOG part number today and I found it at a lot of places. I’d like to know where I could find the RL one. They gave me a part number but it seems to be their internal number. Plus, RL won’t sell me just the arms, I have to buy the lift kit which I don’t need. 
 

Therefore, that has me leaning in the direction of Cognito and now that Bow tie 76 said his Cognitos didn’t squeak I’m pretty much decided.

I decided on and installed the Cognito tubular UCA’s. Install was very easy with no issues at all.

      Cam chain tensioner question

      By B14Sierra · Posted

      So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.

      No low range 4 x 4

      My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      summer road trips in the 2026 2500HD

      By Chuck FB · Posted

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.
