The ICON Vehicle Dynamics V.S. Series 2.5 remote reservoir coilover shocks w/ CDCV are an incredible upgrade for the front end of the2015-Up Colorado / Canyon truck. ICONs Vehicle-specific valving provides a sport tuned feel on and off-road while offering 1.75-3 of lift height adjustability for use of larger, more aggressive wheel and tire combinations. ICON's larger 2.5 shock body and increased piston area over stock components provides improved damping ability and outstanding ride characteristics across varying types of terrain. Remote reservoirs ensure optimum performance by increasing the duration of consistent damping regardless of situation, keeping the shocks at a cooler operating temperature during heavy use.The ICON CDC Valve upgrade is included for those desiring an easy way to tune the ride externally with 10 settings from soft to hard. When paired with ICON rear 2.0 Aluminum Series or 2.5 Series shocks, vehicle control will be balanced front to rear resulting in the best overall driving experience for your Colorado / Canyon.
