What's included

• Vertex 2.5 front coilover shocks (qty 2) — adjustable-reservoir design tuned for balanced on and off-road performance.
• Vertex 2.5 rear shocks (qty 2) — matched to the front for consistent damping across the suspension.
• Radius arm drop brackets — precisely angled to maintain factory caster geometry and factory-like handling.
• Fabricated 4.5-inch rear blocks (No Overload) — anti-axle wrap design eliminates bind and maintains stock ride quality.
• 6-inch coil springs — engineered to work with the drop brackets and rear blocks for true level stance.
• Transfer case clocking kit — re-indexes the transfer case for proper driveline angles after lift installation.

Important notes

• Does not fit F-350 dually models, manual shift transfer cases, gas engine F-250/F-350 models, or vehicles with 4-inch rear axle tubes.
• Not compatible with factory rear contact overload springs or the Tremor Factory Trim Package.
• Transfer case clocking is required to preserve driveline geometry — included in the kit.
