2001-2023 Silverado/Sierra 2500/3500HD Cognito Upper Control Arm Set

So you've added on a leveling/lift kit or maybe some larger wheels and tires to your 2001-2023 Silverado/Sierra 2500/3500HD, and now you're left with a truck that doesn't ride the same as it once did. The reason for this is your OEM Upper Control Arms aren't able to deliver the proper suspension articulation and wheel travel so these upper control arms fix that! 
 
The Cognito Ball Joint SM Series Upper Control Arms add style, function, and performance to your vehicle by improving the allowable droop travel for a better ride quality. The control arm kit features boxed sheet metal arms that are CNC robot welded and powder coated semi-gloss black.
 
The 01-10 still uses the boxed upper control arms with bolt in ball joint. See second picture for example!
