UMI Performance 64015-B Stage 1.5 Handling Kit with Viking Double Adjustable Shocks - Black

The UMI Performance 64015-B Stage 1.5 Handling Kit is a comprehensive suspension upgrade package built entirely in the USA. Designed to deliver exceptional ride quality and handling balance, this kit pairs a heavy-duty tubular front sway bar with a three-way adjustable solid rear sway bar and double adjustable Viking performance shocks. Power Tour and daily driver proven, the Stage 1.5 kit is equally at home on the street, at the drag strip, or carving corners.

The included Viking double adjustable shocks offer 19 independent positions in both compression and rebound — totaling 361 unique tuning combinations — giving you precise control over your suspension setup for any driving condition. The front shocks provide a ride height range of 11-5/8" to 12-5/8", while the rear shocks accommodate a ride height range of 16-5/8" to 18-3/8", making this kit fully compatible with stock-height trucks. Lowered trucks can also be accommodated with the addition of UMI P/N 6411 rear shock relocation brackets.
