What's included
- 3.5-inch lift kit — Engineered steel and forged torsion bar keys for uncompromised durability and simplified bolt-on installation.
- Red forged upper control arms — Maintain proper geometry and full range of motion; available in bold powdercoated red finish with OEM-style Clevite bushings for quiet, reliable operation.
- M1 monotube shock pair (front) — Premium damping tuned for smooth highway ride and off-road capability.
- M1 monotube shock pair (rear) — Precision-tuned to complement the front shocks and deliver balanced, controlled suspension response.
- Driver and passenger side knuckles — Precision-engineered steel knuckles reduce CV bind while optimizing driveline angles; differential drop spacers further refine geometry.
Important notes
- This kit does NOT fit models equipped with rear overload springs due to u-bolt length variances.
- This kit does NOT fit dually models due to u-bolt design differences.
- A torsion bar removal tool (Rough Country part 1067) is recommended for easier installation.
- Wheel backspacing must be verified to safely accommodate 33"–35" tires; consult our team during fitment.
