The ICON Vehicle Dynamics Stage 1 Suspension System for the 2021-2026 Ford Bronco features front and rear 2.5 EXP Series coilovers to yield increased wheel travel along with superior ride quality and suspension performance both on and off-road. 2.5 EXP Series coilovers combine the performance of a fully rebuildable 2.5-inch diameter premium shock absorber with the convenience and cost-benefits of re-using the Bronco’s factory coil spring and other components. EXP coilovers use a series of snap-ring grooves machined into the shock body to provide easily-selectable ride height adjustment from 0-2” of front lift and 0-1.75" of rear lift over stock on Bronco’s equipped with the OE HOSS 2.0 suspension 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 Bronco’s OE upper shock and spring mounts. EXP Series shocks utilize a one-piece digressive piston design and are custom tuned for the Bronco in conjunction with their stock 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. HOSS 2.0 is Ford's upgraded suspension system for Broncos of the Base, Big Bend, Outer Banks and Black Diamond trim levels WITH the optional Sasquatch package, and it is also standard on Badlands, Wildtrak, First Edition and Everglades. HOSS 2.0 is most easily identified by the YELLOW shock bodies of the OE shocks.
