What's included

• 6" Kit Box | Coilover Conversion — top-mounted reservoir brackets and coil-over mounts fabricated from 1/4-inch steel to replace the factory independent coil shock setup.

• Vertex 2.5 Rear Coilovers (pair, 6") — matched monotube shocks for optimal damping control and consistent ride geometry.
• Radius Arm Kit Box & Upgrade Boxes — precision-fit, ultra-durable radius arms at 27 lbs each, bolting into factory mounts with durable rubber bushings for maximum vibration absorption and factory-like suspension angles.
