F250 / F350 2017-2027 Ford 4WD (w/0 to 3 inch lift) Rear Air Suspension Load Leveling Kit by BDS Performance Towing

The BDS 133900 Performance Towing Load Leveling Kit is designed for Ford F-250 and F-350 Super Duty SRW 4WD trucks from stock height up to 3 inches of front lift (0 to 1 inch rear lift). Engineered for towing, hauling, and heavily loaded applications, this air suspension system adds adjustable rear load support while maintaining factory suspension travel and everyday ride quality.

Unlike many traditional air spring systems, the BDS design retains the factory overload springs and uses an integrated mounting system for a clean, straightforward installation. A rubber-isolated lower air spring cradle allows the axle to separate from the air spring at full suspension droop, helping preserve suspension travel during off-road use and uneven terrain instead of limiting articulation.

Heavy-duty air springs operate safely from 0–125 PSI and can be run at zero pressure when the truck is unloaded, helping maintain a smooth factory-like ride. DOT-approved nickel-plated brass fittings, DOT air line, dual inflation valves, and an included tee fitting provide durable, dependable operation with flexible inflation options.

The BDS Performance Towing system helps level and stabilize the truck under load, improving control and reducing rear suspension sag when towing or hauling. It is compatible with all in-bed hitch configurations and works with a wide range of wheel and tire combinations.
