What's included
- 6-inch D-Coil springs — increased ground clearance with progressive spring rate for both on and off-road performance.
- Radius arm drop brackets — maintain proper caster geometry so your truck handles like stock and doesn't fight you on the road.
- Fabricated anti-wrap rear blocks — stronger than cast alternatives and engineered to prevent axle wrap binding while keeping ride quality smooth.
- M1 Monotube shock absorbers (pair, front and rear) — nitrogen-charged N2.0 series shocks deliver balanced performance on highway and trail.
- Block U-bolt kit — secures the rear suspension blocks.
- Extended stainless steel brake lines and brackets — account for the additional ride height and ensure proper brake function.
Important notes
- This kit is engineered for diesel F-250 Super Duty 4WD models without factory rear contact overload springs. Do not fit if your truck has OE overloads or if it is an F-350, dually, or gas-engine model.
- Recommended tire range is 35–37 inches. Larger tires may require trimming or additional modifications.
