4 Inch Lift Kit w/ Radius Arm | Ford F100/F150 (80-96) 4WD

Built for classic truck owners who want 4 inches of lift without sacrificing steering geometry — this BDS kit for your 1980–1996 Ford F100/F150 4WD combines Pro-Ride coil springs up front with extended radius arms that preserve caster angle through the full range of travel. You get up to 33" tire clearance and a stable, predictable steering feel on pavement and dirt alike.

What you get up front

• Pro-Ride coil springs — vehicle-specific, full-length springs engineered for correct 4-inch lift height and smooth, predictable ride across pavement and rough terrain.
• Extended radius arms — high-strength tubular arms replace factory stamped steel and reduce caster change through wheel travel, keeping your steering stable and responsive.
• Axle pivot relocation brackets — correct geometry at the front axle to work with the extended radius arms.
• Radius arm drop mounts — position the arms for optimal control and clearance.
• Forged pitman arm — steering correction geometry built in.
• NX2 Nitro shocks (front) — nitrogen-charged for consistent performance.

Out back

The base kit uses a high-strength lift block, longer u-bolts, and a matching set of NX2 Nitro shocks to handle the rear load. Four variants let you dial in your preferred rear lift method — choose from a 2-inch block, dual add-a-leaf springs for 4 inches, or single-leaf options depending on your truck's needs and payload.

Important notes

• Maximum tire size: 33 x 12.5.
• Front lift is achieved through coil spring replacement; rear varies by kit variant (block or add-a-leaf).
• Extended radius arms are engineered to preserve driveline geometry and reduce caster change — a key benefit for steering stability on lifted trucks.
• Four variants available — confirm your preferred rear lift method (2-inch block, dual add-a-leaf, or leaf spring options) when ordering.
