Icon Vehicle Dynamics 71670E 2.5 VS Remote Reservoir CDEV Front Coilover Reservoir Adjustable Shock Lift 1.75-2.5" Chevrolet Colorado/GMC Canyon AT4/Trail Boss 23-26 Pair

ICON Vehicle Dynamics V.S. Series 2.5" Coilover Shocks

The ICON V.S. Series 2.5" coilover shocks are a front-end performance upgrade designed to deliver greater wheel travel, improved damping, and adjustable ride height for compatible applications. Their longer design provides a 20% increase in total front wheel travel for a total of 10.25" of front wheel travel, while vehicle-specific valving balances on- and off-road performance.

Adjustable between 1.75" and 2.5" of lift, these coilovers allow the use of larger wheel and tire combinations. The larger 2.5" shock body and increased piston area improve damping authority and ride quality across varied terrain.

Remote reservoirs increase oil volume and heat dissipation to resist overheating and cavitation under hard use. The included CDEV (Compression Damping Electronic Valve) provides in-vehicle electronic adjustment of compression damping, responding in under 40 ms and allowing extremely precise, infinitely variable tuning. ICON Intelligent Control and the proprietary ICON mobile app use onboard G-force and gyroscope data to predict terrain and adjust CDEV settings dynamically.
