Built to outperform, upgrade your 2011-2016 Ford Super Duty F250 and F350 diesel truck to the next level with this 6-inch radius arm lift kit with FOX Performance Elite coil-over conversion from BDS. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 37 inch Tires.

Up front the lift kit includes diesel-specific FOX 2.5 coil-over shocks, heavy-duty replacement radius arms, forged drop pitman arm and track bar bracket for steering correction, sway bar relocation, brake line brackets, and custom-tuned secondary FOX 2.0 shocks.

In the rear this kit utilizes a replacement GlideRide leaf springs with integrated overload leaf, u-bolts, brake line brackets and a matching set of NX2 Nitro or FOX Performance shocks.

FOX Performance Elite Coil-Over

FOX 2.5 Performance Elite shocks offer next level performance for on-road comfort and off-road comfort capability. Tuned and ready to install right out of the box, these bolt-on 2.5-inch diameter shocks are built for abuse and packed with race-proven technology.

They include a remote reservoir for additional fluid capacity to keep your shocks running cool so you can push the limits in the rough terrain.

The Dual Speed Compression Adjust adjuster adds remarkable versatility and precise tuning with a simple twist of either two adjuster knobs, offering 10 separate low-speed and 12 high-speed compression levels, with a black anodized aluminum reservoir to increase cooling efficiency.

HD Radius Arms

In place of the 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, service-free operation.

BDS Glide-Ride Leaf Springs

Built to outperform, BDS engineered the Glide-Ride leaf springs into a multi-leaf progressive spring rate design that provides a smooth ride with any load. This is accomplished with an exclusive triple-stage leaf spring design where the main leaf pack is broken into two stages:

1. First, the primary three leafs are functional with no additional load in the vehicle for excellent everyday ride quality. As moderate loads are applied, the secondary leafs are engaged.
2. Second, if the truck is fully loaded, the bottom overload is engaged for maximum hauling capacity. This setup allows your truck to maintain ride quality unloaded without sacrificing payload.

Upgrading to BDS Glide-Ride leaf springs will reduce axle wrap and provide flexibility throughout the suspension cycle.
