Icon Vehicle Dynamics 71605 2.5 VS Internal Reservoir Front Coilover Shock Lift 0-3.5" Chevrolet Silverado/GMC Sierra 1500 19-26 Pair

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

ICON V.S. Series 2.5" coilover shocks are a front-end upgrade for 2019–2026 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks, and 2021–2026 Chevrolet Tahoe & Suburban and GMC Yukon & Yukon XL SUVs. These coilovers increase total front wheel travel to 9" (approximately 20% more than stock) while remaining compatible with stock front upper control arms. Vehicle-specific valving delivers a sport-tuned feel on- and off-road, and adjustable ride height supports larger, more aggressive wheel and tire combinations.

• Increased travel: Longer shock length yields a total of 9" front wheel travel (about 20% increase over stock).
• Adjustable lift: Pickup trucks: 1.5–3.5" of front lift over stock; SUVs: 2.5–3.25" of front lift over stock (vehicle-dependent).
• Vehicle-specific tuning: Valving tuned for superior damping and control both on-road and off-road.
• Robust construction: 2.5" CAD-plated shock bodies with increased piston area for improved damping.
• Durable internals: Internal nitrogen reservoir for consistent performance under hard use; 7/8" hardened chrome-plated shafts.
• Premium components: ICON-engineered coil springs, 6061 aircraft-grade aluminum CNC-machined components, and PTFE-lined spherical bearings for extended longevity.
• High-strength hardware: CNC-machined lower bar pin and application-specific mounting hardware.
• Serviceable and tunable: Fully rebuildable and re-tunable for extended service life and performance refinement.
