2.5 Inch Lift Kit w/ Radius Arm | FOX 2.5 Performance Elite Coil-Over Conversion | Ford F250/F350 Super Duty (17-19) 4WD | Diesel

Built for diesel Super Duty owners who want 35-inch tire capability without sacrificing on-road composure — this 2.5-inch radius arm lift kit pairs heavy-duty geometry correction with FOX 2.5 Performance Elite coil-over shocks tuned specifically for diesel weight and abuse. You get factory-location radius arms, caster correction, and a steel track bar that keeps your steering dialed in across the entire lift range.

What you get up front

• FOX 2.5 Performance Elite Coil-Over Shocks — bolt-on 2.5-inch diameter units with remote reservoir, DSC adjusters (10 low-speed and 12 high-speed compression settings), and black anodized aluminum body for cooling efficiency. Tuned diesel-specific and race-proven.
• Heavy-Duty Tubular Radius Arms — replace factory stamped steel with high-strength units that mount in original locations. Built-in caster adjustment lets you dial geometry across lift heights, and OE-style rubber bushings keep it quiet.
• 1-3/8″ Solid Steel Track Bar — maintains proper steering geometry and axle centering at lift height. Pre-assembled with bushings, bolt-in installation.
• Sway Bar Relocation & Brake Line Brackets — keeps your front end stable and clears suspension travel without modification.

Out back

High-strength fabricated lift block, longer u-bolts, and a matching set of FOX Performance shocks work together to level your truck and absorb impacts whether you're cruising or tackling rough terrain.

Pick your shocks

• FOX 2.5 Performance Elite Coil-Over — included in this kit. Remote reservoir, DSC dual-adjuster knobs, and 22 total compression settings give you race-level tuning for both highway and trail. Black anodized aluminum keeps fluid temps down under sustained abuse.

Important notes

• This kit is engineered for 4WD Super Duty diesel models (2017–2019) only. Do not install on gasoline engines or 2WD trucks.
• Maximum tire clearance: up to 35 inches. Verify backspacing and offset with your wheel choice to avoid suspension or frame contact.
• Factory radius arms are replaced; the kit preserves caster correction across a wide lift range by design.
• Sway bar relocation and track bar adjustment are included to maintain steering feel and front-axle centering — both critical at this lift height.

Why customers pick this at Road Runner

• FOX Performance Elite shocks are dialed in before they leave the factory — no guesswork, no secondary tuning needed.
• Caster-corrected radius arms mean your truck steers straight and tracks true, not pulling or wandering under load.
• BDS warranty backed locally by technicians who install these kits every week and know every fastener by heart.
• Mount and balance available keeps your downtime to a minimum and your truck back where it belongs — on the road or trail.
