The 2022-2023 Toyota Tundra EXP Series front shock absorbers by ICON Vehicle Dynamics combine the performance of a fully rebuildable 2.5-inch diameter premium shock absorber with the convenience and cost-benefits of re-using the Tundra’s factory coil spring and other components. EXP bridges the gap between spacer lifts and threaded bodied coilovers, providing suspension lift, custom-tuned performance and maximum travel, all in an economical package. EXP Series 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, with the shaft ends machined to re-use the Tundra’s OE upper shock and spring mounts. The 6061-billet aluminum coil spring seat is CNC machined to fit the molded heavy duty urethane coil spring seat that is specifically designed to fit the Tundra’s OE coil spring. A series of snap-ring grooves machined into the shock body provide easily-selectable front-end ride height adjustment from 0" to 3” of lift over stock. EXP Series shocks utilize a one-piece digressive piston design and are custom tuned for the Tundra 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.
