The Cognito 110-90298 Ball-Joint Style Upper Control Arms replace the factory control arms on your 2011-2019 GM 2500HD/3500HD 2WD/4WD. Cognito designed these control arms for leveled and lifted applications where an upgrade is desired to provide better performance, style, and function. These boxed sheet metal arms are powder coated semi-gloss black. Alloy series ball joints are included along with new crush sleeves and polyurethane bushings. These control arms help add performance to the Chevy and GMC truck by correcting the ball joint angle for lifted and leveled applications, increasing droop travel, and also increases caster slightly for better highway speed drivability.

  • Polyurethane Bushings
  • Corrected Ball Joint Angle
  • Added Caster
  • Semi-Gloss Black Powder Coating
  • Made in the USA

Note: These upper control arms are NOT designed to be a droop travel limiter. You must use Cognito specified shocks and lift kit to limit droop travel or else damage to this arm and other components of the suspension and drivetrain may occur.

Purchased Order #1314739 was completed on 1/22/21 and had a professional (suspension shop) installed. I don't know the mileage but have had my tires rotated three times since. Went in over the weekend (10/15/22) for an oil change and tire rotation when I was told that an alignment could not be done because the ball joint went out. $600 plus labor and didn't last two years. Ooh, and there's no warranty :(

Quck fix
I placed order #1309149 for the cognito upper a arms kit for my 2017 denali duramax which had worn out a arms at 47000 miles. These fit right and went in without a hassle with all neccesary parts included for the swap. Had it aligned and was on the road in a snap with no more noise and a tighter front end. Cheaper than other places, easy install sturdy built parts.

Questions and Answers

Do these upper control arms provide any amount of lift?
View Staff Answer 
No, these upper control arms will not provide any amount of lift. The torsion bar is what changes ride height on your 2012 2500HD.
Do these come with the ball joint or are those bought separately? Thanks!
View Staff Answer 
Ball joints are included!
Would these fit on a truck with stock suspension height?
View Staff Answer 
Yes, these control arms will work on a stock height truck.
