Jeep Comanche MJ Camp Series Long Arm Upgrade Kit
Upgrade your Jeep Comanche MJ with the Camp Series Long Arm Upgrade Kit, the ultimate suspension enhancement for strength, stability, and ride quality. Unlike radius-style long arm systems that create single points of failure, our true long lower and upper control arms provide superior articulation, proper geometry correction, and increased suspension travel. This design improves both on-road comfort and off-road capability, giving you complete control in any terrain.
Key Features and Benefits
- Superior Suspension Travel – True long arms provide a smoother, more consistent range of motion, reducing binding and improving ride quality.
- Heavy-Duty Construction – Built from .313-inch wall DOM tubing with high-grade polyurethane bushings and Johnny Joints for maximum durability.
- Enhanced Stability – Corrects suspension geometry, keeping your wheels planted for better handling on highways, trails, and technical rock climbs.
- Fully Adjustable Design – Accommodates lifts from as little as 2 inches, making it ideal for low center of gravity (LCG) builds or high-clearance setups.
- High-Clearance Crossmember – 3-piece design allows easy drivetrain access without sacrificing strength.
Recommended Pairing
For a complete front-end upgrade, pair this kit with our Camp Series Track Bar (CMP-J-MJ-FTB1) to further improve axle centering and suspension performance.
Maximize Performance and Ride Quality
The Camp Series Long Arm Upgrade Kit optimizes your Jeep’s suspension geometry, ensuring proper articulation and reducing stress on components. By relocating the control arm mounts away from the axle, this system enables maximum suspension travel and eliminates binding—providing unmatched ride quality for daily driving, off-road crawling, and heavy towing.
Two-Stage Powder Coating
Each component undergoes a two-stage powder coating process for superior corrosion resistance and long-term durability.
Zinc Primer Base Coat – Provides a protective layer against rust and corrosion.
Durable Top Coat – Available in 10 custom colors, allowing you to match or contrast your Jeep’s suspension while adding extra durability.
