CST Performance Suspension



The CST CSS-C2-10 Upper Arm Kit includes pre-installed Uni-balls with tapered pins that are designed for use with the factory GM steering knuckles. These arms are a 100% bolt-on item. No cutting, welding, or machining is required to install them. CST has built this Upper Arm Kit to satisfy the demand of CST customers that wanted the strength of a uni-ball but in an easier to maintain and longer lasting design. If you've got a 2011+ 2500HD or 3500 Silverado or Sierra this is a great suspension upgrade. Use of the Uni-Ball instead of a ball-joint allows the CST arm to operate at more severe angles without binding and when paired with the correct shock absorber this Control Arm can provide increased suspension travel and better ride quality when the truck is driven off-road. Oil field guys (and gals) prefer this CST Upper Arm over the factory arm because the CST version can withstand severe off-road punishment.

This item includes everything shown in the product image. Please note, you will reuse the factory frame to control arm mounting hardware. CST includes new urethane pivot bushings, bushing sleeves, and Zerk fittings that allow you to easily grease the control arm pivot bushings.
