Installed and serviced at Road Runner Wheels & Tires. Most lift kits go in the same day. Call (678) 400-6467 to schedule.
What's included
- Knuckles — redirect suspension geometry to maintain proper caster and alignment under the new ride height.
- Crossmember box — provides a high-clearance mounting point that keeps the differential tucked higher without cutting or modifying factory mounts.
- 5-in / 7-in lift kit box — structural kit components sized for your lift specification.
- Vertex 2.5 adjustable front coilovers (qty 2) — dampened coil springs tuned for load-carrying capacity and ride quality at full height.
- Rear subframe and yoke kit (6 inches) — restores ride angle and geometry at the rear axle.
Important notes
- Does NOT fit models equipped with Auto Ride or Auto Leveling air suspension.
- Does NOT fit models with electric power steering.
- AWD models require full driveline conversion to non-AWD — this is a structural modification, not a bolt-on adjustment.
- Minor cutting and drilling of the frame is required during installation.
- 18-inch wheels or larger are mandatory; smaller wheels may not clear the suspension.
- Consult the installation instructions for detailed tire and wheel compatibility before purchase.
