Key Features Benefits
- Heavy-duty DOM tubing construction – Built from 5/16” wall DOM tubing, these control arms are engineered to withstand the toughest conditions. The lower control arms utilize 1.75” OD tubing, while the uppers feature 1.5” OD tubing, ensuring superior durability over stock and competitor options.
- Johnny Joints for maximum flexibility – Every control arm is equipped with RockJock Johnny Joints at both ends, allowing for extreme articulation without binding. These joints provide unparalleled durability, smoother operation, and enhanced longevity compared to traditional rubber or poly bushings.
- Adjustability for perfect suspension geometry – Designed to accommodate lifts from 0 to 6 inches, these adjustable control arms allow you to fine-tune axle positioning, caster, and pinion angles for optimal drivability and handling. For lifts beyond 6 inches, contact us for additional options.
- Pair with a front track bar or rear A-arm for a complete suspension solution – For the best results, we recommend pairing this set with our Crawl Series Front Track Bar (CRL-J-WJ-FTB1) or Rear Adjustable A-Arm (CRL-J-WJ-AA1). This ensures proper axle centering, stability, and alignment—giving you a fully optimized suspension system for both on- and off-road driving.
Two-Stage Powder Coating
Each control arm undergoes a two-stage powder coating process to maximize durability and corrosion resistance. A zinc primer base coat creates a solid barrier against rust, followed by a top coat in your choice of 10 colors for a custom look.
Proudly Made in the USA
Manufactured in Orem, UT, our Crawl Series Control Arm Set exemplifies American craftsmanship and engineering. We oversee every step of the process to ensure the highest quality, sourcing materials locally to maintain strict manufacturing standards.
