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

Discontinued - Out of production and no longer available for purchase.

This CST Performance Suspension CSS-C2-9 Pro-Joint Upper Control Arm is designed for use on the 2001 through 2010 model year GM 2500HD and 3500 series 2wd and 4x4 trucks. CST has perfected their own Pro-Joint and it now features a rebuildable design. The Pro-Joint offers more angular capability than a Uni-Ball and is 100% sealed against the elements. This means a properly greased and serviced Pro-Joint will last much longer than an unsealed UniBall. That means longer service intervals and a lower cost of ownership.

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.
