More Information

The Icon Vehicle Dynamics 78735 2.5 VS (vehicle specific valving) PB (piggyback reservoir) CDCV (compression damping control valve) Shock Absorbers for the GMC Sierra 2500HD / 3500HD models are an amazing suspension upgrade. These shocks feature a 10-postion adjustment dial on the resi that allows you to fine tune the ride from smooth to firm. Constructed from a massive 2.5 inch 6061 aluminum body that increases oil capacity and houses a 7/8 diameter chrome shaft. The external reservoir improves performance by adding more oil capacity for better heat dispersion and resistance to fading.

Also included in this kit are Icon billet aluminum upper control arms. These arms are constructed from CNC machined 6061 billet aluminum for light weight and exceptional strength. Featured are the amazing Delta Joints that combine the durability of a ball joint with the performance of a uni-ball. Ideal when paired with Icon coilovers to increase wheel travel which translates into better suspension performance and ride quality. Engineered with built-in caster correction for optimal alignment specs, serviceable dual stage poly bushings and FK rod end 7/8 inch heim joints for smooth operation.
