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

This variant includes a Block Kit and Add-A-Leaf rear lift configuration. Cast iron lift blocks with new center pins are paired with an add-a-leaf to freshen worn factory leaf springs. This multi-leaf progressive design reduces axle wrap for a more controlled and stable feel while maintaining factory payload weight ratings.
