CST GM 2500HD & 3500 Pro-Joint Upper Arms # CSS-C2-9

The CST CSS-C2-9 Upper Arm Kit includes pre-installed ProJoint ball-joints 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. The CST Pro-Joint ball-joint allows the CST arm to operate at more severe angles without binding. This is important when running a lift or leveling kit and extended length shock absorbers. The Pro-Joint also features a grease fitting which allows you to keep the joints properly lubricated.

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