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.

upper control arms look great and went on easy.. only reason I gave 4 stars and not 5 is because of a shipping issue which put my build a week behind. The issue was resolved quickly and painlessly, great customer service. Only time will tell how control arms perform but they look great and like they will go above and beyond control arm demand.

Have full upper/lower CA set on both front and rear axles on a 96 ZJ. These are the rubber bushing sets not joint sets. I have beat the hell out it in the Nevada desert for 2 years and has been great. I don’t go fast but I do articulate suspension a lot. Super solid and haven’t any issues. Just inspected the entire set recently due to some banging under it. Turns out the banging is lower rear shock bushings. Inspected each CA along the way nothing. Aside from dirt and obviously winter roads and what not still in excellent condition, bushings are solid like the day they were installed. I’ll add that I’m about tapped on a short arm at 4.25(less with settle) so the front CA’s get beat on just from that, still they’re like new. Paint is great condition, this set is red. I would definitely buy again. Another plus for me, Utah isn’t local necessarily, but it’s nice to support businesses closer to me.

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!

The whole process was quick and painless. The products are top tier and when I reached out them for package update info, Korby Linscomb was very responsive, and got me the answers I needed the same day. Even when I emailed back to some additional info, he sent what I was looking for that same day. I love core 4x4 and will be giving them my business from now on.
