The Dirt King Bolt-On Bump Stop Kit is engineered to give your rear suspension additional support and protection against harsh bottom-outs on rough terrain. This kit bolts directly to the frame using existing holes — no drilling or guesswork required — and includes a frame support to help reduce frame flex during off-road use. The bump stop mounts are designed to accept large bump stop units (such as King or Fox 2.5″ × 2.5″), letting you fine-tune suspension dampening and progression to your terrain and driving style. You can also choose versions with integrated strike pads and shock mounts for additional functionality, especially when used with a prefab bed cage system.
Compatible with the 2015–2020 Ford F-150 (2WD/4WD) and 2017–2020 Ford Raptor 4WD, this kit is ideal for trucks equipped with spring-over leaf springs like Deaver packs or equivalents. It helps keep the suspension from harshly bottoming out and increases confidence over rough trails.

To install, position the bump stop mounts onto your truck’s rear frame using the existing holes. Secure them with the included Grade 8 hardware and torque to specification. If you are using bump stops (King or Fox 2.5″ × 2.5″), install bump stop strike pads on the axle where they will make contact during suspension compression. Optionally, use versions with integrated shock mounts if you are running a prefab bed cage or want to mount shock reservoirs at the strike point. Check clearance and articulation through full suspension travel after installation to confirm proper operation.
