2.5 Inch Lift Kit w/ Radius Arm | Ford F250/F350 Super Duty (17-19) 4WD | Diesel

Built for diesel Super Duty owners who need 35-inch tire clearance and confidence in rough terrain — this 2.5-inch radius arm lift kit levels your stance, opens up your suspension geometry, and pairs factory-proven components with adjustable caster correction so your truck handles as good as it looks. You get diesel-specific Pro-Ride coil springs, tubular radius arms, and an adjustable track bar that keeps your steering dialed in across all lift heights.

What you get up front

• Pro-Ride Diesel-Specific Coil Springs — full-length springs engineered for the weight and torque of your diesel engine, delivering smooth ride quality across pavement and trail.
• HD Tubular Radius Arms — heavy-duty replacements for factory stamped steel, mounted in original locations with caster adjustment and OE-style rubber bushings for quiet, service-free operation.
• Adjustable Track Bar — 1-3/8" solid steel construction that recenters your front axle at lifted heights and maintains steering geometry and handling precision.
• Sway Bar Relocation — factory-compatible bracket work to keep suspension articulation smooth without bind.
• Brake Line Brackets — precision-bent hardware to protect your brake system during suspension movement.

Out back

A fabricated lift block, longer u-bolts, and your choice of shock package (see below) round out the rear end — all matched to front geometry for level, predictable handling.

Pick your shocks

• NX2 Nitro Series — comfortable daily driver shocks with nitrogen charge for consistent dampening and ride feel over thousands of miles.
• FOX 2.0 Performance Series — tuned for smooth pavement and light off-road use, with improved damping control and durability.
