Product Description

The UMI Performance 656063-2 is a complete front and rear lowering kit for 4WD 2015-2025 Ford F-150 trucks. It combines a coilover front system with adjustable leaf spring shackles and a flip kit in the rear to deliver a fully tuneable stance - up to 4" in the front and 6.5" in the rear - without sacrificing daily drivability. Viking double-adjustable shocks front and rear provide 361 damping combinations each, allowing the truck to be dialed in from comfortable street cruising to autocross or drag strip performance.

Unlike competing kits that often introduce vibration or harshness, UMI engineered this system with longer leaf spring pins, new bump stops, and included U-bolt spacers specifically to address these issues. The front mounts directly to the factory lower A-arms with no A-arm replacement required, and the heavy-duty 3/16" laser-cut steel bracketry is built to handle both street and track abuse. Note that PowerBoost hybrid models are not compatible, and trucks with headlight sensors will need the separately sold UMI P/N 6576 bracket.
