MaxTrac 303430 F-150 2WD 3"/4WD 4" Rear Flip Kit

Lower Your F-150 with a Complete Rear Flip System

Transform the rear stance of your 2009–2014 Ford F-150 with the MaxTrac 303430 Rear Flip Kit. Designed for both drivetrains, this package provides approximately a 3" rear drop on 2WD models or a 4" rear drop on 4WD models while combining the primary axle and leaf-spring components needed for the conversion.
The kit includes axle relocators, hangers, shackles, bump stops, and spring plates, giving you a coordinated rear lowering package without having to source the major flip components individually.

Key Features

Designed for approximately 3 inches of rear drop on 2WD F-150s and 4 inches on 4WD F-150s.

Axle Relocators Included

Application-specific axle relocators reposition the rear axle relative to the leaf springs as part of the lowering conversion.

Hangers & Shackles

Included rear hangers and shackles work with the axle flip components to establish the intended final ride height.

Heavy-duty spring plates provide essential mounting components for the axle and leaf-spring assembly.

Bump Stops Included
