4 Inch Lift Kit | Ford F250/F350 Super Duty (08-10) 4WD | Diesel

Built for F250/F350 diesel owners who demand real hauling geometry and tire clearance without compromise. This 4-inch lift preserves your truck's turning radius and driveline angles while opening up to larger tires. Choose between block-style (with or without factory overload springs) or traditional leaf-spring architecture — both engineered to handle the weight and torque of your diesel platform.

Installed and serviced at Road Runner Wheels & Tires. Most kits go in the same day. Call (678) 400-6467 to schedule.

What you get up front

• Front coil springs — engineered to maintain factory ride quality and load-carrying capacity on diesel weight.
• Caster-corrected brackets — keeps your steering geometry true and prevents bump-steer on rough terrain.

Out back

Block kits use precision-machined blocks to lift the rear axle and preserve your factory overload springs (if equipped) — or delete them for a smoother ride without the springs. Leaf-spring kits replace your factory springs entirely with new progressively-wound units that handle diesel torque and payload without sagging.

Pick your shocks

• BDS NX2 Nitro Series — smooth, predictable performance for daily driving and towing; internal nitrogen keeps you level under load.
• FOX 2.0 Performance Series — external reservoir tuning for technical terrain and long highway hauls; adjustable damping refines your ride on the fly.

Important notes

• Block kits are available with or without factory overload springs — confirm your current setup before ordering.
• Leaf-spring kits replace your factory springs; inspect driveshaft angle and transfer-case clearance during install.
• Factory-option air suspension (if equipped on your model year) is not compatible — confirm before purchase.
