These control arms deliver superior handling and stability, enhancing your vehicle’s capabilities both on and off the road.
Superior Construction
Crafted from premium 5/16” wall DOM Tubing, our upper and lower control arms are built for strength and endurance. Featuring original Johnny Joints at both ends, these components deliver outstanding off-road articulation while maintaining durability and resilience, outperforming factory parts and other aftermarket options.
Easy Adjustability for Precision Alignment
Designed with left and right-hand threaded bodies, these control arms provide effortless adjustability. Fine-tune your suspension setup directly on the vehicle to achieve optimal axle centering and pinion angle adjustments. The Crawl Series Rear Control Arms Set accommodates lifts ranging from 0 to 6 inches, ensuring precise alignment and improved performance. For lifts beyond 6 inches, additional solutions are available upon request.
Durable Two-Stage Powder Coating
All control arms are subjected to a dual-layer powder coating process. Starting with a zinc primer for corrosion resistance, each arm is finished with a top coat in your choice of color from our palette of 10 options. This ensures a robust finish that resists harsh environmental conditions while allowing you to customize your vehicle's appearance.
