Well, kinda. I took care of things myself by buying 6mm Gorilla hubcentric rings from ReadyLift. They were machined to go from factory hub bore to 106mm bore of the MotoMetal wheels. They were perfect for what I needed and gave me a bit more thread engagement on the studs. https://www.readylift.com/6mm-wheel-spacers-gm-1500-2019-2021.html
Hi, has anyone installed these arms on their truck, I’m wondering what alignment specs you wound up aligning it to. RC and RL give alignment specs but Cognito doesn’t other than saying to set up cross caster and that a professional alignment shop will understand and be able to get it set up. Thanks
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 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.
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?

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
