Why Builders Choose CORE 4X4

Warranty facts, not marketing language.

vs. MetalCloak

Their “lifetime” language refers to their service model. Actual parts warranty: 1 year. Ours: lifetime.

vs. Teraflex

Skip a maintenance interval? Their warranty voids. Ours doesn’t.

vs. Clayton Off Road

Clayton warrants their Johnny Joints for 90 days. We cover ours for life.

Enhanced Suspension Performance and Alignment

Upgrade your Jeep Wrangler JK (2007-2018) with the Camp Series Front Upper Control Arms, designed to restore proper alignment, improve handling, and enhance off-road articulation. Whether tackling rugged trails or maintaining highway drivability, these control arms provide superior strength, adjustability, and durability, ensuring a smoother and more controlled ride.

What's Included in the Kit?

  • Camp Series Front Upper Control Arms (CMP-J-JK-FU2)

Key Features and Benefits

  • Precision Suspension Alignment – Helps correct caster angle and re-center the front axle after a lift, preventing steering instability and improving overall handling.
  • Heavy-Duty DOM Tubing Construction – Built from 1.5" OD DOM tubing with a .313" wall thickness, making these control arms significantly stronger than factory components.
  • Advanced Joint Technology – Features a Johnny Joint at the adjustable end for unmatched articulation and flexibility, while the axle end connects via a U-bracket to the factory bushing, maintaining seamless compatibility.
  • Adjustability for Lifted Vehicles – Fully adjustable to accommodate 0 to 6 inches of lift, allowing for precise caster correction and front axle alignment. For lifts beyond 6 inches, please contact us for additional options.
  • Recommended Pairing – For a complete front-end suspension solution, we recommend pairing these control arms with our Camp Series Front Lower Control Arms (CMP-J-JK-FL2) to fully optimize steering alignment and caster correction.

Correcting Caster for Improved Steering Stability

One of the most critical aspects of suspension geometry is caster angle, which directly affects your Jeep’s steering stability and control. Improper caster—often caused by lifting your vehicle—can result in wandering, unpredictable steering, and excessive following of road ruts. By adjusting the front upper control arms, you can restore the proper caster angle, ensuring a smoother, more predictable driving experience on highways and improved control in off-road conditions.

Two-Stage Powder Coating

Our dual-layer powder coating process ensures exceptional durability and corrosion resistance. Zinc primer base coat protects against rust and corrosion. Top coat, available in 10 colors, provides additional protection and allows you to customize your suspension components.

Made in the USA

Proudly manufactured in Orem, UT, our Camp Series Front Upper Control Arms are built with locally sourced materials and crafted under strict quality standards. Supporting American manufacturing means investing in superior craftsmanship and long-lasting durability.

Optional Hardware Upgrade

This kit is designed for easy installation using factory hardware. If your Jeep has rusted or worn-out bolts, we offer optional Grade 8 hardware kits, available separately, to ensure a seamless installation process.

In Conclusion

The Camp Series Front Upper Control Arms provide essential caster correction, enhanced durability, and improved articulation, making them a must-have upgrade for lifted Jeep JK owners. Designed for maximum performance on and off the road, these control arms help restore proper alignment, ensuring stability, precise steering, and a more enjoyable driving experience. Upgrade today and take full control of your Jeep’s suspension!

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.

Have yet to get to try them but I bought some upper, and then later , lower control arms for my 03 rubicon. The pricing is very fair, so fair I was hesitant to even purchase. When the product came in I was happily mistaken. These are some beefy units with an incredible warranty! I’m very excited! I went with the “Camp”series as I mostly daily it. I have trouble with the shipping at times when I ordered but Corby is quick to notice things and help communicate the solution. Looking forward to buying more parts!

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!

Good company, they offer well built parts and Great customer service. I had a couple of hang ups with my control arms that I purchased, they were very easy to work with and found the solution to make them work.

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!

Absolutely incredible family owned business. I asked to pick up my order since I’m local and they came in on a weekend to accommodate. Had to make some adjustments to parts and took the time to make sure it was perfect. Parts are incredible quality. If you have a Jeep, do not hesitate to support this local business.

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.

I ordered a part for my 03 Jeep TJ and all I can say is wow! Korby at Core 4x4 is a total rockstar!! There was a glitch with my payment and within minutes, Korby reached out to me to get it fixed, then sent my receipt with the tracking number. I lost the number and reached out to him during the Holidays and got a rapid response with the number again. I can’t say enough about the customer service and the quality of parts. Thank you!!
