CST 2011 - 2019 GM HD UniBall Upper Arm Driver Side # CSS-C2-10D

The CST 2011 - 2019 Chevrolet and GMC 2500HD / 3500 Upper Arm # CSS-C2-10D one Driver Side Control Arm, pre-installed Uni-ball, and installation hardware. These upper control 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. CST redesigned their control arms and they now feature a sealed upper top cup design. This design effectively prevents dirt and contaminants from building up on top of the Uni-Ball and prevents premature wear.

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.
