BDS 4 Inch Lift Kit w/ Radius Arm | Ford F250/F350 Super Duty (2005-2007) 4WD Diesel | Block Kit With Factory Overload | FOX 2.0 Performance Series

Rear lift achieved with a steel block kit configured for trucks with factory top-mounted overload springs. Blocks are fabricated from high-strength steel, designed to provide correct pinion angles and maximum ground clearance.

Equipped with FOX 2.0 Performance Series shocks featuring a 2-inch impact extruded aluminum body, internal floating piston (IFP) monotube design, massive 5/8-inch hard chrome plated heat-treated alloy steel shaft, CNC machined 6061-T6 aluminum mounting ends, race-developed high-flow piston, application-specific valving, and a long-lasting clear anodized finish.

Overview

This 4-inch radius arm lift kit from BDS Suspension is designed for 2005–2007 Ford F250 and F350 Super Duty diesel trucks. The kit improves stance, performance, and capability, providing clearance for up to 35-inch tires. Up front, the kit includes diesel-specific Pro-Ride coil springs, heavy-duty tubular replacement radius arms, a forged drop pitman arm and track bar bracket for steering correction, sway bar relocation, brake line brackets, and precision-tuned nitrogen-charged shocks. In the rear, the kit is available with either a high-strength steel lift block (with u-bolt flip kit for maximum ground clearance) or replacement rear leaf springs, along with brake line brackets and a matched set of shocks.

Important Notes

These trucks were manufactured with and without top-mounted overload springs on the rear leaf springs. A top-mounted overload is an extra leaf separate from the pack that is set above the main leaf. You will need to identify which you have before ordering. If your vehicle is equipped with a carrier bearing, you will need to order 123402 in the accessories section. Does not fit dually models; dual rear wheel trucks require custom u-bolts to be made.
