ICON V.S. 2.5 Aluminum Series shocks are designed and built to give your vehicle outstanding performance off-road and a smooth ride on the street. They feature remote reservoirs and are 100% rebuildable/revalveable.
ICON Vehicle Specific (V.S.) 2.5 Aluminum Series shocks are designed and built to give your vehicle outstanding performance off-road and a smooth ride on the street. These shocks are configured specifically for each application in both length and damping tune. Like all ICON shock absorbers, V.S. 2.5 Aluminum Series shocks are 100% rebuildable and 100% revalveable. For piggyback and specific remote reservoir applications, ICON’s unique use of a 6061 billet aluminum manifold a few inches below the top cap of the shock creates an internal “Bump Zone” that when used creates an additional 20% of damping force. This additional force helps prevent harsh bottom outs and controls the suspension when compressing at high velocity. If you are looking for a more user defined tune, consider ICON compression adjustable shock absorbers equipped with CDCV, CDXS, or CDEV.
- Compatible with 0-3.5" of front lift over stock
- Premium grade 5WT shock oil for consistent suspension damping along a wide temperature range
- Nitrogen charged monotube design with remote reservoir
- One-piece digressive piston design with vehicle specific valving for unsurpassed performance and ride quality on and off-road
- 7/8” diameter induction hardened, chrome plated shock shaft
- Press in, bonded rubber bushing/bar pin assembly damps road vibration and provides OE factory type fitment
- 6061 aircraft grade aluminum CNC machined components
- One-piece, hard anodized, impact extruded aluminum cylinders offer excellent corrosion resistance and consistent finish
- All ICON 2.5 Aluminum Series Remote Reservoir shocks can be upgraded with an ICON compression adjuster (CDCV, CDXS, or CDEV)
- 100% Rebuildable
- 100% Revalveable
- Extended travel length requires aftermarket front upper control arms and provides maximum wheel travel
- ICON’s internal “Bump Zone” increases damping by 20% to provide more control as the shock approaches full compression
- Remote reservoir design improves heat dissipation to reduce shock fade during prolonged use
