What's included
- 6" Kit Box | Coilover Conversion — Top-mounted reservoir brackets and coil-over mounts fabricated from 1/4-inch steel, engineered to accept 2.5-inch Vertex coilovers and handle sustained damping loads.
- Vertex 2.5 Adjustable Front Coilovers (LH & RH) — Nitrogen-charged, 8-stage adjustable monotube shocks with 56% greater fluid capacity than average reservoir shocks, paired with external reservoirs for superior oil capacity and damping sensitivity.
- Vertex 2.5 Rear Coilovers (qty 2) — Matching monotube rear shocks engineered for optimal load control and ride consistency.
- Radius Arm Kit Box & Upgrade Boxes — Ultra-durable radius arms at 27 lbs each, precision-fit to factory mounts with durable rubber bushings for vibration absorption and factory-like suspension angles.
- 4.5 In Block U-Bolt Kit (No Overloads) — Fabricated lift blocks stronger and longer-lasting than cast equivalents, with specially designed anti-axle wrap geometry to maintain stock ride quality.
- Transfer Case Clocking Kit — Re-indexes the transfer case to preserve driveline geometry and eliminate binding.
Important notes
- 10-speed transmission models require removal of the dial pin before installation.
- Does NOT fit gas engine models, manual shift transfer cases, or dually configurations.
- Does NOT fit vehicles equipped with the Tremor Factory Trim Package.
- New fabricated lift block replaces factory-equipped lift block — not compatible with factory blocks.
