4 Inch Lift Kit | 1973-1976 Ford F100/F150 4WD | Block Kit & Add-A-Leaf Rear | BDS Suspension

This configuration pairs the cast iron lift block kit with an Add-A-Leaf to help freshen up old, worn-out factory leaf springs. The add-a-leaf features a multi-leaf progressive design for a smooth ride while maintaining factory payload weight ratings. Tapered blocks restore correct pinion angle; offset steel pin and hole restore axle position.
