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.

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.


  • Vehicle Fitment: Jeep Comanche MJ 86-92 – Engineered for improved suspension articulation, enhanced stability, and superior ride quality.

  • CORE Advantage: True long-arm design with 4-link long arms, creating a wider suspension arc for superior flexibility and smoother suspension cycling.

  • Adjustability: Adjustable from 0 to 6 inches of lift, with custom solutions available for lifts beyond 6 inches to ensure optimal suspension geometry.

  • Construction: 1/4-inch plate steel brackets, high-clearance crossmember, and 5/16” wall DOM tubing, delivering unmatched durability and off-road capability.

  • Two-Stage Powder Coating: Zinc primer base and top coat available in 10 vibrant colors protect against corrosion and allow for personalized styling of your rig.

  • Warranty and Origin: Proudly manufactured in the United States, our product includes a lifetime warranty on all non-wear items, providing you with confidence and peace of mind in your purchase.

Got the CAMP version of adjustable control arms and track bars for our 03 TJ with a 3” lift and 33x10.5 KO 2’s. Super beefy bars, great fit and adjustability. Friendly advice and support from Korby at CORE 4X4. Good follow up as well. The ride quality is great as well as the handling. I think it all looks pretty good as well.

Great customer service. I got my front upper and lower control arms and hardware on Friday afternoon. It didn’t come with instructions so I called Core 4X4 and they immediately e mailed me the instructions. Also, the kit I got had the spacers missing so I called. It was late Friday by thus time but they took care of the issue first thing Monday morning and I got the spacers on Tuesday. Great company.

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.

Great company, who worked with me on shipping parts, to arrive in time for a show, when I explained my concern of possibly not getting the control arms in time. Quality is amazing on the part, affordable price for what you get, and the powdercoat is top notch, not a single issue with this product, would buy again.

Outstanding experience! I asked Core to build me a set of custom control arms that were larger/heavier than they normally build. They gladly accepted the challenge and turned out an expertly crafted and super strong product ahead of schedule. Fit and finish are excellent. Spence and Cameron were a pleasure to work with every step of the way. And all of this for a very reasonable price. I highly recommend these guys!

Great experience with Core 4x4! I purchased some suspension parts for my dad's 98 Jeep TJ. The products they make are super durable and look even better in person. Attention to detail and overall superior quality. The staff at Core 4x4 is super helpful also, Korby has been great. Updating me on the status of my order and sending me tracking numbers as well. Thank you all at Core 4x4, keep up the amazing work!

Core 4x4 has outstanding products at a fair price and unmatched customer service. When you call Korby, it's like talking with a friend. Very cool and helpul! I ordered some custom control arms, but from the wrong product line and they were super cool about returning them and upgrading to a better "Crawl" series. Only charged the difference between the two products. They paid all the return shipping and sent the uprgaded arms super quick. It was only a couple days. Awesome!! I couldn't be happier with the transaction👍🏼 Also, these control arms are stout and take a beating. I run heck out my Jeep in the rocks and desert. No problems whatsoever. Thanks Core 4x4, ya'll are welcome at my campfire anytime! Jake T. Pleasant Hill, Or.

I have recently come to know Core 4x4 when I purchased a Jeep XJ and was looking for a place that had dedicated XJ suspension and components. Here is what makes them different than most other shops. All of their components are top shelf quality and they back it up if you break any of it. I was able to see their shop when I picked up an order locally and was impressed with their attention to detail and how they assemble and powder coat each part. I had an issue with a shackle and needed the threaded shaft to be shorter. I called in and talked to Kaden and he told me to come by and they would shorten it for me. When I got there, Kaden and Spencer (the owner) met me and talked about options and proceeded to make the right adjustments to fit my XJ. Told me if anything changes in the future and I need additional length, they would take care of me. So what really sets them apart from others is their Customer Service. Try calling in to any other Jeep suspension or part shop and see how they treat you. Been there - done that. Will continue to do business with Core and their team. Getting that kind of service for just a shackle has me thinking I may need to replace my JT components with Core's. Thanks Guys for being helpful good humans!
