Superior Suspension Performance for Your Jeep Comanche MJ
Upgrade your Jeep Comanche MJ with the Crawl Series Long Arm Upgrade Kit, designed to enhance axle stability, optimize suspension geometry, and improve overall ride quality. Unlike radius-style long arms that create single points of failure, this long arm design features both long lower and upper control arms, delivering superior strength, stability, and articulation for on-road comfort and off-road performance.
Key Features and Benefits
- Long Arm Design – Maximizes suspension travel, improves ride quality, and eliminates the binding issues of short arms.
- Heavy-Duty Construction – Built with .313-inch wall DOM tubing for superior strength and durability in extreme conditions.
- High-Clearance Crossmember – Designed for improved ground clearance and obstacle navigation.
- Adjustable for Various Lift Heights – Works with lifts from 2 inches and up, making it a perfect low center of gravity (LCG) option for better stability.
- 100% Bolt-On Installation – Includes weld surfaces for those seeking additional reinforcement.
Built for Strength and Performance
The Crawl Series Long Arm Upgrade Kit is engineered for maximum articulation and control. With long upper and lower control arms, your Jeep’s suspension cycles on a longer arc, allowing for smoother and more predictable handling. This reduces driveline strain and provides better overall ride quality, whether on technical rock crawls or daily commutes.
Optional Axle Side Upper Bushing Upgrade
While factory bushings offer adequate performance, they can wear prematurely under extreme conditions. We offer two upgrade options:
- Polyurethane Replacement Bushings – Provides increased durability and longevity.
- Rock Jock Axle Side Johnny Joint Upgrade Kit – Replaces factory rubber with Johnny Joints for the best articulation and longevity (cutting and welding required for installation).
Two-Stage Powder Coating for Maximum Durability
Every component in this kit undergoes a dual-layer powder coating process for superior protection.
Zinc Primer Base Coat – Provides corrosion resistance to prevent rust.
Durable Top Coat – Available in 10 color options to customize your Jeep’s suspension.
Made in the USA
Proudly manufactured in Orem, UT, the Crawl Series Long Arm Upgrade Kit is built to the highest American craftsmanship standards. By sourcing local materials and maintaining strict quality control, we ensure a premium product that delivers unmatched durability and performance.
