Key Features and Benefits
- Heaviest tubing for upper and lower control arms – Lower control arms are constructed from 1.75” OD DOM tubing with a 5/16” wall thickness, while upper control arms use 1.5” OD DOM tubing with the same robust wall thickness for maximum durability.
- Johnny Joints for superior flexibility – Each control arm is equipped with Johnny Joints at both ends for unmatched articulation and longevity. The front upper control arms feature a U-bracket at the axle end, attaching to the factory-installed bushing.
- Adjustable for lift heights from 0 to 6 inches – Enables precise alignment correction, axle centering, and pinion angle optimization to eliminate driveline vibrations.
- Recommended pairing – When all 8 control arms work in sync, your suspension is fully dialed in for improved handling and off-road capability.
Durable Powder Coating for Maximum Protection
Every control arm undergoes a two-stage powder coating process for superior durability and corrosion resistance. A zinc primer base coat enhances rust protection, while the top coat—available in 10 color options—provides long-lasting resilience and customization.
Proudly Made in the USA
The Crawl Series reflects the highest standards of American manufacturing. Built in Orem, UT, using locally sourced materials, every component undergoes rigorous quality control to ensure maximum strength, reliability, and longevity.
Optional Hardware Upgrade
This kit is designed for straightforward installation using factory hardware. For those dealing with rusted or stubborn bolts, optional Grade 8 hardware kits are available separately to ensure a seamless setup.
