BDS1939FPE | BDS Suspension 4 Inch Lift Kit With Radius Arm & Fox 2.5 Performance Elite Coil-over Conversion For Ford F-250/F-350 Super Duty 4WD | 2008-2010 | Diesel | Rear Lift Leaf Springs

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 DSC 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.

Steering Correction

To optimize steering geometry once lifted, a forged drop pitman arm is used to minimize the steering angle and pair it with a heavy duty track bar drop bracket to keep them in phase through suspension travel while recentering the front axle.

Rear Lift Option

Block Kit

• Blocks made of steel for high strength.
• Designed to provide correct pinion angles.

Leaf Springs

• Eliminates any need for a lift block.

Important Notes

2. If your vehicle is equipped with a carrier bearing, you will need to order 123402 in the accessories section.
