Rear lift is achieved with a 4 Inch Steel Block Kit + Add-A-Leaf (With Overload) — select this option if your truck was manufactured with top-mounted overload springs (an extra leaf sitting above the main leaf pack). The add-a-leaf uses a multi-leaf progressive design for a smoother ride, reduces axle wrap, and maintains factory payload weight ratings.
Equipped with NX2 Nitro Series shocks featuring a nitrogen-charged twin-tube design, 10-stage velocity-sensitive valving, dual-welded ends for increased strength, a 1-3/8-inch high-flow piston, self-lubricating seals, and a silver powder coat finish.
Overview
This 6-inch radius arm lift kit from BDS Suspension is designed for 2005–2007 Ford Super Duty F250 and F350 gas trucks, providing clearance for up to 37-inch tires while improving stance, performance, and capability. Up front, the kit includes gas-specific 6-inch lift Pro-Ride coil springs, heavy-duty tubular replacement radius arms, a forged drop pitman arm, a track bar bracket for steering correction, sway bar relocation, and brake line brackets. In the rear, the kit utilizes high-strength steel lift blocks (or optional leaf springs), longer U-bolts, and brake line brackets. All configurations include vehicle-specific shocks in either NX2 Nitro or FOX 2.0 Performance Series.

Important Notes
- Removal of the factory block is required.
- Installation of the rear block kit will result in a "pre-runner" look with the rear of the vehicle 2 inches lower than the front. To achieve a level stance, upgrade to the rear leaf spring option.
- 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 sits above the main leaf. You will need to identify which configuration your vehicle has before ordering.
- If your vehicle is equipped with a carrier bearing, you will need to order part #123402 in the options section.
- Although extremely rare, front driveline vibration may occur.
- Front exhaust modification may be required to clear the front driveshaft on gas models.
- U-bolts will not fit dually models.
- Dropped pitman arm will not fit 10-lug wide track F350 models.
