MaxTrac 203440 F-150 4WD 5" Rear Lowering Box Kit

Give Your 4WD F-150 a Deeper 5" Rear Drop

Lower your 2009–2014 Ford F-150 4WD with the MaxTrac 203440 5" Rear Lowering Box Kit. This matched rear suspension package includes a flip kit, rear hangers, bump stops, and two MaxTrac 2400LL-9 rear shocks to provide the primary components needed for a 5" rear drop.

The 203440 is designed to work with the appropriate MaxTrac front lowering components when building a complete 3" front / 5" rear lowering system. If your F-150 is equipped with a factory rear lift block, removing that block can produce additional drop equal to the height of the block.
