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.

What's Included?

  • True Long Lower Control Arms (2)
  • True Long Upper Control Arms (2)
  • 1/4-Inch Plate Steel Brackets and Crossmember (3-Piece Crossmember for Drivetrain Access)

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.

Made in the USA

Proudly manufactured in Orem, UT, the Camp Series Long Arm Upgrade Kit reflects the highest standards of American craftsmanship. By sourcing local materials and overseeing the entire production process, we ensure top-quality products built to withstand the toughest conditions.

Optional Hardware Upgrade

This kit is designed for a 100% bolt-on installation, with surface areas available for welding if desired. Optional Grade 8 hardware kits are available separately for a seamless installation.

In Conclusion

The Camp Series Long Arm Upgrade Kit is the ultimate suspension solution for Jeep Comanche MJ owners looking to enhance stability, articulation, and ride quality. Whether you're conquering rugged trails or daily driving, this kit delivers the strength, adjustability, and performance needed for any adventure. Upgrade today and transform your Jeep’s suspension capabilities!

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!

We have all shopped places where the person on the phone makes you feel like they don't have the time to talk to you the customer or answer your questions. I can tell you first hand that's not Core 4x4. They have the best customer service I have seen so far. They have taken the time to respond to all of my questions in a very prompt and professional manner, taking the time to answer each and every question I have had. Lets put it this way if Core 4x4 sells a product I am wanting for my truck I will buy it from them, I highly recommend Core 4x4.

Ordered a set of Core 4x4 control arms for my 2006 Jeep TJ. These are some heavy duty quality control arms. Can't wait to get them installed. Great customer service too!

I wanted to take a moment and give these guys a shout out, I’ve currently got, for my xj, their adjustable control arms, tier 4 adjustable track bar and adjustable leaf spring shackles. You can always count on a fair price, high quality products, and quick delivery. Keep up the great work guys, will definitely continue to shop with you
