What you get up front

• Pro-Ride Coil Springs — diesel-specific, full-length coils engineered to deliver smooth, predictable ride on and off pavement.
• HD Tubular Radius Arms — heavy-duty forged units with caster adjustment built in, mounted at factory locations with OE-style rubber bushings for quiet, service-free operation.
• Forged Drop Pitman Arm & Track Bar Bracket — minimizes steering angle and keeps geometry in phase through suspension travel, recentering the front axle without bind.
• Sway Bar Relocation, Brake Line Brackets — all clearance and safety hardware included.

Out back

Your choice of leaf springs or block kit. Leaf spring option gives you articulation and compliance; block kit with u-bolt flip maximizes ground clearance. Both come with brake line brackets and your choice of shocks.

Pick your shocks

• BDS NX2 Nitro Series — comfort-tuned, nitrogen-charged dampers that smooth out bump-and-dip on daily drives and light trails.
• FOX 2.0 Performance Series — dual-speed compression, rebound adjusters, and internal floating piston for maximum control on rough terrain and high-speed desert runs.

Important notes

• Maximum tire size is 35 x 12.5. Oversized tires will compromise geometry and handling.
• Block kits are available with or without factory overload springs — choose based on your rear spring pack configuration.
• Leaf spring option carries its own valving and load rating — verify your current setup with us before ordering.
• Fits 2008–2010 Ford F-250 and F-350 Super Duty 4WD diesel models: XL, XLT, Lariat, King Ranch, Harley-Davidson Edition, FX4.
