Upgrade your 2023-2025 Ford F250/F350 Super Duty diesel with this 5" radius arm lift kit and FOX 2.5 Performance Elite coil-over conversion from BDS, with clearance for up to 37" tires. Up front it includes diesel-specific FOX 2.5 coil-over shocks, heavy-duty tubular replacement radius arms with caster adjustment, a forged drop pitman arm and track bar bracket for steering correction, sway bar relocation, and brake line brackets.

The FOX 2.5 Performance Elite shocks include a remote reservoir for added fluid capacity and cooling, plus Dual Speed Compression adjustment offering 10 low-speed and 12 high-speed settings to dial in for any terrain.
