ICON Vehicle Dynamics Extended Travel CDCV Reservoir Coilover # 71555C. Designed for use on 2007-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 2wd and 4x4 trucks. These ICON Extended Travel coilover shocks work best with the addition of an aftermarket upper control arm kits offered by ICON as they are designed specifically for use with these coilovers.

ICON # 71555C coilovers feature a large 2.50" diameter shock body and external reservoir equipped with CDCV that helps improves suspension damping and handling while enhancing the vehicle performance on and off the road. The ICON CDC Valve is an externally adjustable valve that restricts oil flow into the reservoir which creates 10 levels of compression damping force ranges.allows  This is a race quality shock absorber designed to provide superior performance on the street and still provide good off-road performance. The spring rate of the coil spring on the ICON coilover is a little higher than the factory spring. This provides a more performance oriented feel and better handling both on and off-road.
