What's included

• Radius Arm Kit Box — ultra-durable radius arms (27 lbs each) with durable rubber bushings, precision-fit to factory mounts for easier installation and factory-like suspension angles.
• 6" Kit Box | Coilover Conversion — top-mounted reservoir brackets and coil-over mounts constructed from 1/4-inch steel for maximum durability.
• Vertex 2.5" Adjustable Coilovers (Front Left & Right) — nitrogen-charged, 8-stage adjustable monotube shocks with 2.5-inch pistons and external reservoirs; 56% greater fluid capacity than average reservoir shocks for superior damping control.
• V2 Monotube Shock Pair — precision-engineered rear shocks optimized for this lift configuration.
