ICON's 2.5 Series piggyback reservoir shocks are part of a Stage 4 7" lift system developed for 2008–2010 Ford F-250/F-350 Super Duty trucks. The kit balances increased wheel travel and ride quality while preserving towing capacity, clearing 37" tires. ICON engineers matched dual-rate springs, radius arm drop brackets and 2.5" reservoir shocks to work together for consistent damping across varied terrain.
