EXP Series shock absorbers by ICON combine the performance of a fully rebuildable 2.5-inch diameter premium shock absorber with the convenience and cost-benefits of re-using the vehicle’s factory coil spring and other components.
EXP Series for the 2019-2026 Chevrolet Silverado 1500/GMC Sierra 1500 is based on ICON’s proven 2.5-inch diameter Aluminum Series shock absorber, featuring a one-piece impact-extruded aluminum shock body. Hard anodizing provides a great-looking, consistent finish with superior resistance to abrasion and corrosion. The massive 7/8-inch diameter shaft is induction hardened and chrome plated. EXP shocks use the factory shaft-up orientation. The 6061-billet aluminum coil spring seat is CNC machined to fit the truck’s OE coil springs. A series of snap-ring grooves machined into the shock body provide easily-selectable front-end ride height adjustment from 2.375” to 3.75" of lift over stock. EXP Series shocks utilize a one-piece digressive piston design and are custom tuned for the 2019-2023 GM 1500 in conjunction with their stock front coil springs to maximize damping performance and provide unsurpassed ride quality, on and off-road. The increased piston size and shock oil volume provided by the 2.5-inch diameter aluminum body also provide superior heat dissipation compared to the smaller, steel bodied OE shocks, resulting in longer-lasting shock performance over prolonged use at higher speeds and through rougher terrain. For those who would like to further tune their suspension, EXP shocks are fully re-valvable (and rebuildable) by any qualified shock technician, with parts available from ICON.
