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.

I just finished installing the Peak 2.0 Front Suspension system with the Core 4x4 Blue Tacoma Rear Suspension system on my 2024 TRD Offroad Premium Tacoma. The two upgraded suspension systems really made a difference in how the ride feels, whether we’re off-road or on the road. A big thank you to Korby and the team at Core 4x4 for their support and for getting the shipping sorted out so quickly!

The folks at Core 4X4 are always wonderful to deal with. They explain your options and never pressure or rush things. The quality of the Core Control Arms is top shelf, especially if your goal is to stop wheel hop. I recommend Core 4x4 without reservation ! ! !

First off: Korby, the gentleman that helped me decide on which kit to go with is EASILY the nicest, and most patient person I’ve dealt with, when ordering parts for this build. Second: the quality of the product is INSANE! These parts are so nicely fabricated, then powder coated for extra longevity, and they even offer an aluminum upgrade in some cases (which I went with, to save weight). Having said all of this, the most impressive thing was the lead time. These parts are build to order, and I literally ordered my suspension one week ago, today! Yes, they built, powder coated, packaged, shipped my suspension components (RAM 1500 Track rear trailing arm full set in 7075 aluminum, and front upper control arms), AND they arrived, all within a week! Granted, that I’m only one state away, but WOW!!! One week?! Amazing! So, in sort: excellent products, which arrived excellently packaged (no damage, an boxes not over-stuffed with heavy suspension parts; three boxes total, as opposed to one super heavy one…my back thanks you), super quickly, and customer service that ANY business would be envious of….so, if you’re in the market, absolutely go with 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!

Awesome control arms! My mechanic said “ your Jeep is pretty much bulletproof now.” And I just got the tier 1 arms! The people at the core 4x4 shop were really nice too. They were running behind on shipping, (which is understandable) so I decided to go pick it up because it was only an hour drive. They gave me a free $60 hardware kit for the inconvenience. Thanks core 4x4! You guys are awesome!!

Amazing service. Bought a track bar through Americantrucks.com and they sent it with the wrong size bushing sleeve. Korby at Core 4x4 was quick to get me the correct size and very responsive. Will definitely be using more of their stuff.

Every product I have received from them has been nothing short of fantastic. Korby in Customer service went above and beyond to help me fix my own mistake. I cannot reccomend them enough.

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.

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.
