This variant includes the rear block kit configured for trucks equipped with top-mounted overload springs (an extra leaf sitting above the main leaf pack). High-strength steel lift blocks provide correct pinion angles and a controlled, stable feel. Note: installation of the rear block kit results in a "pre-runner" look with the rear sitting approximately 2" lower than the front. Upgrade to the leaf spring option for a level stance.
Overview
This 6-inch radius arm lift kit with FOX 2.5 Performance Elite coil-over conversion is designed for 2008–2010 Ford Super Duty F250 and F350 diesel trucks (4WD). The kit is engineered to improve stance, performance, and capability, providing clearance for up to 37-inch tires. Up front, the kit includes diesel-specific FOX 2.5 coil-over shocks, heavy-duty tubular replacement radius arms, a forged drop pitman arm and track bar bracket for steering correction, sway bar relocation hardware, brake line brackets, and custom-tuned secondary FOX 2.0 shocks. The rear of the kit utilizes high-strength lift blocks, longer U-bolts, brake line brackets, and a set of FOX Performance shocks — with an optional rear leaf spring upgrade available.
Features
- FOX 2.5 Performance Elite coil-over mounts in the factory coil bucket location
- Adds an additional secondary FOX 2.0 shock for maximum performance
- Eibach coil springs for smooth performance through rough terrain
- Heavy-duty tubular steel radius arms that correct caster while maximizing ground clearance
- Track bar relocation bracket and pitman arm maintain proper steering angles for improved handling
- Fabricated steel blocks provide level stance from front to rear (with leaf spring option)
- FOX shocks are fully serviceable and resistant to corrosion and harsh environments
FOX 2.5 Performance Elite Coil-Over
The FOX 2.5 Performance Elite shocks are 2.5-inch diameter bolt-on units built for demanding off-road use. They include a remote reservoir for additional fluid capacity to help keep shocks running cool. The DSC (Dual Speed Control) adjuster provides 10 separate low-speed and 12 high-speed compression levels via two adjuster knobs. The reservoir features a black anodized aluminum finish to increase cooling efficiency. These shocks are tuned and ready to install out of the box.
HD Radius Arms
In place of factory stamped steel radius arms, BDS supplies a pair of high-strength tubular radius arms. These arms mount into the factory location and offer caster adjustment for a wide range of lift heights, along with an OE-style rubber bushing at the frame mount for smooth, quiet, and service-free operation.
