Drop the Rear of Your F-150 by 5 Inches

Give your 2015–2026 Ford F-150 4WD a lower, more aggressive stance with the MaxTrac 203240 5" Rear Lowering Box Kit. This matched rear suspension package combines a 303240 flip kit, hangers, bump stops, and two MaxTrac 2400LL-9 rear shocks to provide a complete 5" rear lowering solution.

Why Choose MaxTrac 203240?

The MaxTrac 203240 packages the primary rear suspension components needed for a 5" F-150 4WD drop into one matched box. Instead of sourcing the flip components, hangers, bump stops, and shortened shocks separately, this package combines the 303240 flip assembly with two 2400LL-9 rear shocks and the supporting components needed for the installation.

It can also serve as the rear half of a complete 3"/5" MaxTrac lowering setup when combined with the appropriate front components, making it useful for both rear-only suspension projects and complete lowered F-150 builds.

Perfect For

F-150 4WD street truck builds
5" rear lowering projects
3"/5" complete drop systems
Rear axle flip conversions
Replacement lowering components
