Upgrade your 2011–2016 Ford F-250/F-350 with a precision-engineered 2.5-inch Stage 4 suspension kit featuring independent expansion pack shocks for maximum off-road control.

Transform your Super Duty’s ground clearance and articulation with a fully integrated suspension system built around 2.5-Series diameter coilovers specifically calibrated for 2011 through 2016 Ford platforms.

• Deliver exactly 2.5 inches of balanced front and rear lift while preserving factory ride compliance for predictable street handling.
• Eliminate hydraulic fading during sustained trail use via dedicated external expansion pack cylinders mounted directly behind each shock body.
• Accommodate up to 35x12.50 factory-width tires immediately, preventing frequent scrubbing and sidewall stress on uneven terrain.
• Restore precise steering geometry and prevent brake hose tension with included extended brake lines and reinforced track bar mounts.
• Withstand repeated compressive loads through billet aluminum shock bodies, hard-chromed stainless steel internal components, and heavy-duty zinc-plated mounting hardware.
• Bolt directly onto existing frame and spindle points without drilling, cutting, or aftermarket spacer blocks.

This configuration is verified for 4-wheel-drive gasoline models produced between 2011 and 2016. It does not install on diesel variants, Tremor trims, or Cab & Chassis derivatives. The system ships with pre-valved front and rear shocks, progressive coil springs, extended bump stops, and all necessary fasteners for a direct replacement. Engineered to absorb high-mileage abuse and resist corrosion under salt-heavy road conditions, the assembly maintains structural rigidity and load-carrying capacity without requiring frequent realignment.
