Key Features and Benefits

- Heavy-Duty Steel Construction – Built to outlast and outperform factory control arms, these arms offer superior impact resistance and long-term durability.
- Tapered Polyurethane Bushings for Responsiveness – Designed for improved articulation, vibration dampening, and better road feel, compared to standard rubber bushings.
- Full Adjustability for Lifted Vehicles – Ideal for suspension lifts from 0 to 6 inches, restoring proper axle position and caster alignment to maintain smooth handling and reduced driveline vibrations. For lifts beyond 6 inches, contact us for additional solutions.
- Complete Suspension Solution – For full control over axle positioning, pinion angles, and suspension geometry, pair this set with our Cruise Series Rear Control Arm Set (CRS-J-JK-RS4). Together, they provide a comprehensive upgrade for improved handling, stability, and long-term durability.
