Rear lift is achieved via a steel block kit configured for trucks without factory top-mounted overload springs. Blocks are high-strength steel, designed to provide correct pinion angles and maximize ground clearance. Paired 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, and application-specific valving for maximum on- and off-road performance.
Overview
This 4-inch radius arm lift kit from BDS Suspension is designed for 2005–2007 Ford F250 and F350 Super Duty gas trucks. The kit improves stance, performance, and capability while providing clearance for up to 35-inch tires. Up front, the kit includes gas-specific Pro-Ride coil springs, heavy-duty 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 a steel block lift option or replacement leaf springs, along with brake line brackets and a matching set of shocks. Rear block kits are available in two configurations to accommodate trucks built with or without factory top-mounted overload springs.

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.
