Designed for 2007-2018 Jeep Wrangler JK models, this set includes both Front Upper Control Arms (CMP-J-JK-FU2) and Front Lower Control Arms (CMP-J-JK-FL2), providing a comprehensive suspension upgrade. Whether you’re conquering rough terrain or cruising the highway, these control arms deliver superior strength, flexibility, and precise alignment adjustments to optimize your driving experience.

  • Two-stage powder coating for corrosion resistance, available in 10 colors.

  • Recommended pairing: Camp Series Front Track Bar (CMP-J-JK-FTB1) for a fully optimized front suspension setup.

Caster Correction Axle Centering for Better Drivability

When lifting a Jeep Wrangler JK, the front axle naturally shifts off-center, and the caster angle decreases, leading to poor steering response, increased wandering, and a lack of stability. Correcting these issues is crucial for maintaining proper drivability.

Caster Angle Restoration

The lower control arms play a key role in regaining caster, helping the front tires return to center after a turn and preventing the Jeep from following road ruts or wandering. Proper caster correction improves straight-line stability and reduces steering effort, making lifted vehicles safer and more predictable to drive.

Axle Centering Alignment

The upper and lower control arms work together to recenter the front axle, ensuring proper wheel positioning for correct steering geometry and minimized tire wear. When paired with our Camp Series Front Track Bar, you achieve full front suspension correction, eliminating handling inconsistencies caused by lifting your Jeep.

Built for Strength and Performance

Crafted from heavy-duty DOM Tubing with a .313" wall thickness, these control arms are engineered for extreme durability. The design features: Johnny Joint at the adjusting end for maximum articulation and flexibility off-road. Tapered polyurethane bushing at the axle end for vibration dampening, reducing road noise while maintaining a smooth ride.

This combination delivers the best of both worlds—enhanced articulation for off-road performance and exceptional road comfort.

Adjustability for Perfect Alignment

Our adjustable control arms accommodate lifts from 0 to 6 inches, allowing precise adjustments to caster, pinion angles, and axle positioning. With full adjustability, you restore the proper geometry lost during a lift installation, improving your Jeep’s handling, reducing stress on suspension components, and maximizing tire longevity.

For lifts beyond 6 inches, contact us for additional options and support.

Resilient Two-Stage Powder Coating

To ensure long-term durability, our control arms undergo a two-stage powder coating process, providing superior corrosion resistance and an eye-catching finish: Zinc Primer Base Coat – Protects against rust and environmental wear. Top Coat in 10 Custom Colors – Allows you to customize the look of your suspension while adding an extra layer of durability.

Proudly Made in the USA

Every Camp Series product is manufactured in our Orem, UT facility, ensuring the highest standards of quality and craftsmanship. By sourcing raw materials locally and maintaining in-house production, we deliver superior products while supporting American manufacturing.

Optional Hardware Upgrade

These control arms are designed to install easily using factory hardware. However, for rusted or stubborn bolts, we offer optional new Grade 8 hardware kits (available separately) to ensure a seamless installation.

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!!

I have a 2016 RAM 1500 Crew Cab and I replaced the rear upper and lower control arms also the pan hard track bar and also the sway bar and links for the rear with all I had the articulating bushings. The vehicle now has no body role. They are absolutely incredible if you get the control arms you gotta get the CORE 4 x 4sway bar end links don’t don’t try and be cheap and get Moog or something else you got to get articulating bushings get the core 4 x 4 ones they are the best. My truck drives now through the canyons like a BMW. I have Fox high-performance shocks on there as well with all the CORE 4 x 4 suspension parts and they are amazing. Well worth the money I would highly recommend anybody thinking about CORE 4 x 4 go with CORE 4X4 and if you can go with their articulating bushings, they’re unbelievable drives better now than my Escalades. Well planted no body role and smooth on the Highway unbelievable the difference they all made!! THANKS AGAIN CORE 4x4!!!!

Phenomenal company - very rare to come by in the automotive industry. Also very impressing. Let me start here. I got a set of yellow sway bar end links for my 19 ram DT (new body style) and let me tell you, I’m hooked. For numerous reasons. One the craftsmanship behind the product is unmatched for sure for without breaking the bank. 2ndly, they stand behind their product. Had a very minor issue and it was resolved in a blink of an eye!!! Insane. Just because of what i listed above i will forever spend my money with core 4x4! And i think you should too! I have no affiliation at all with this company besides being a consumer. I will be ordering my yellow UCAs and the rest of my rear suspension from them here shortly! Korby on the other hand. The representative that helped me went above and beyond FAST. I hung up the phone with him, and with in no lie 3 minutes he was calling back with an answer. GREAT GREAT GREAT customer service, Korby you and core 4x4 are what give us hope in the car community! With much love and great health to you all!!

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.

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.

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.

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

2001 Wrangler TJ- i have purchased all front/rear upper/lower control arms. Front track bar and rear track bar. Quality is excellent and extremely durable you can tell its built to last. Bent a bolt on the front track bar and called and spoke with Spence. He immediately sent me out new hardware plus some! Product is amazing but what really separates companies apart is their service and these guys are second to none. Thank you all!
