Lower Your F-150 Without Replacing the Factory Leaf Springs

The MaxTrac 303140 Rear Lowering Flip Kit is engineered specifically for 2004–2008 Ford F-150 trucks, offering a clean 4-inch rear drop while retaining your factory leaf springs. Unlike traditional lowering methods that require expensive replacement leaf packs, this innovative system relocates the rear axle and raises it within the suspension assembly to achieve the desired drop while maintaining excellent ride quality and everyday drivability.

Constructed from heavy-duty steel and finished in MaxTrac's durable grey powdercoat, this complete flip kit provides a straightforward installation and dependable performance. Pair it with MaxTrac front lowering springs for a complete lowered truck setup that delivers both style and value.
