Optimize Your Jeep Wrangler TJ/LJ’s Rear Suspension with the Camp Series Rear Control Arm Set (1997-2006)
The Camp Series Rear Control Arm Set is the ultimate suspension upgrade for Jeep Wrangler TJ and LJ owners (1997-2006) seeking improved drivability and durability. Featuring both rear upper and lower control arms, this kit provides complete control over axle centering, pinion angle adjustments, and suspension alignment. Specifically engineered for lifted Jeeps, these arms work in unison to reduce driveline vibrations, ensuring optimal performance and a smoother ride on-road and off.
What’s Included:
- Rear Upper Control Arms (CMP-J-TJLJ-RU2)
- Rear Lower Control Arms (CMP-J-TJLJ-RL2)
Engineered for Strength and Precision
- Constructed with heavy-duty DOM Tubing, the lower control arms are made from 1.75" OD tubing, and the uppers use 1.5" OD tubing, each featuring a .313" wall thickness for maximum strength.
- Each arm is equipped with a Johnny Joint at the adjusting end for unparalleled articulation and flexibility, while the axle ends feature tapered polyurethane bushings for vibration dampening and increased durability.
Adjustable for Lifted Jeeps
- Designed to accommodate suspension lifts from 0 to 6 inches, this control arm set allows you to precisely re-center the rear axle and adjust the pinion angle for improved driveline geometry.
- This ensures a smoother ride and reduces stress on your suspension components, particularly in lifted applications where alignment correction is critical.
Built to Last
- Each control arm is treated with a durable two-stage powder coating process, including a zinc primer base for superior corrosion resistance and a top coat available in 10 colors, allowing you to customize your Jeep’s appearance while ensuring long-lasting protection.
Made in the USA
- Proudly designed and manufactured in Orem, UT, the Camp Series Rear Control Arm Set is crafted with locally sourced materials and built to the highest standards of American quality and craftsmanship.

Select your lift size in Step 1 — the kit ships with the correct geometry for that height. If you’re running a non-standard setup, call us before ordering and we’ll confirm compatibility.
Death wobble is a geometry problem, not just worn parts. Cruise Series corrects caster angle and eliminates the flex points that let shimmy start. Replacing one part at a time delays the fix — this replaces the geometry.
Yes, if you’ve done a lift kit before. Full-day project. Watch the complete JT install walkthrough on our YouTube channel — most owners wrap it in a day. Any off-road shop can run it if you’d rather have it done.
Any non-wear component fails — we replace it. No mileage cap. No maintenance intervals to track. No fine print about voiding if you miss a service. Lifetime means lifetime.
Teraflex’s lifetime warranty voids if you miss a maintenance interval. MetalCloak’s actual parts warranty is 12 months — their “lifetime” language refers to their service program. No conditions here.

Ordered a control arm and track bar kit for my WJ from Core 4x4 on Monday 7/28 and received it today, Friday 8/1. Im not a state or two away, im in CT aka the other side of the country. Communication is phenominal, emails were responded too in an hour or less. Parts arrived well packed, not damaged, and are great quality for my needs. There arent many companies left that service customers as well as Core 4x4 and i wont hesitate to check them out again if i need something else. Well done!

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts.
All around just seems like they don’t care.

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.

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.

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!

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 ! ! !

I want to share a truly positive experience.
I ordered a car kit consisting of two packages, but unfortunately one was lost during shipping with UPS. The situation could have become complicated... but it didn't.
The company manager was extremely helpful and professional: he personally followed up on the situation and did everything he could to resolve the issue, even sending me the package again without hesitation.
It's rare to find such attentive and reliable customer service these days.
My sincere congratulations on your professionalism and commitment: that makes all the difference.

First time buying from Korby @ Core 4x4 and it’s being nothing short of a great experience. I bought the non adjustable Trail kit for my 5th Gen Ram 1500 with a 2” lift. The welds look great, nice powder coat finish and quality bushing. Had some trouble fitting the grease nipples due to the powder coating but a thread tap would fix that. They fit easily and perform great. I felt the improvement straight away. No more wheel hop on hard acceleration which was my main reason for the purchase.
I was missing some smaller bushings needed for the 5th Gen and Korby’s custom service was on point, with responsive emails and mailing out the missing parts straight away. Very happy with their products and customer service. Highly recommended company👌🏽
