Fits as stock replacement or leveled and lifted applications where an upgrade is desired to provide better performance, style, and function. Ample droop travel is required for good ride quality and all suspension components to last and work properly.

This control arm kit will add performance to the Chevy and GMC truck by correcting the ball joint angle for lifted and leveled applications. The allowable droop travel is also improved with the design of these arms. Made in the USA.

Best UCA Available

Cognito makes the best upper control arms in the business for the Sierra/Silverado 1500. One recommendation for the guys at Cognito - please add a mounting hole for the wheel speed sensor and brake sensor brackets. I added M8 rivnuts to my control arms to use the factory GM brackets.

Question

Many companies offering leveling kits for the Trail Boss indicate that the Auto 4WD function should not be used due to increased CV angles. Is that a concern with your UCAs? I don’t want to sacrifice that functionality.

Answer

Hi Joshua, We do not over-articulate CV axle angles on any of our products. In this case, you'll notice our AT4/ TB kits reduce the amount of lift over stock compared to the non-AT4/TB models. This is to account for the 2" in increased ride height...

Question

Do these control arms have serviceable ball joints and if so are they bolt on or pressed on?

Answer

Hi Eddi, Our ball joints are maintenance-free, so they are not designed to be serviced. Over the years, we have seen a much longer service life for maintenance-free than serviceable ball joints. Most people take their vehicles to lube shops that do...
