Upgrade Your Jeep Grand Cherokee WJ’s Suspension
Enhance your Jeep Grand Cherokee WJ’s performance with the Camp Series Front Upper Control Arms. Designed to improve handling, alignment, and stability, these control arms are essential for maintaining optimal suspension geometry and drivability on lifted vehicles. Built for strength, flexibility, and durability, they are a substantial upgrade over factory components, ensuring exceptional performance on and off the road.
What’s Included
- Camp Series Front Upper Control Arms (CMP-J-WJ-FU2)
Key Features and Benefits
- Engineered for strength and durability – Constructed from 1.5" OD DOM Tubing with a .313" wall thickness, these control arms are built to handle extreme conditions while maintaining on-road comfort.
- Premium joint technology – Features a Johnny Joint at the adjustable end for superior articulation and a U-bracket at the axle end, ensuring a secure and reliable connection.
- Adjustable for lifted vehicles – Fully adjustable to accommodate lifts from 0 to 6 inches, allowing precise alignment correction, axle positioning, and improved handling.
- Recommended pairing – Works best when paired with our Camp Series Front Lower Control Arms for a complete front-end solution, especially for lifts over 3 inches to maintain proper geometry and reduce driveline vibrations.
Durable Two-Stage Powder Coating
Each control arm is treated with a two-stage powder coating process for maximum protection against corrosion and wear. A zinc primer base coat ensures rust resistance, while the top coat—available in 10 color options—adds an extra layer of durability and customization.
Optional Hardware Upgrade
Designed for straightforward installation using factory hardware, these control arms make upgrading your suspension simple. For rusted or stubborn bolts, optional Grade 8 hardware kits are available separately to ensure a hassle-free installation.

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.

Great customer service. I got my front upper and lower control arms and hardware on Friday afternoon. It didn’t come with instructions so I called Core 4X4 and they immediately e mailed me the instructions. Also, the kit I got had the spacers missing so I called. It was late Friday by thus time but they took care of the issue first thing Monday morning and I got the spacers on Tuesday. Great company.

Ran into an issue with a part that I ordered. Got ahold of them explained to them the issue I was having and they jumped in and got the issue fixed. Hands down the best customer service I have ever dealt with. The parts are hands down amazing. Highly recommend.

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 bought the 16pc Cruise Series Adjustable Control Arm, Track Bar, Steering, End Link Kit to replace a worn budget 4" lift on my used JKU. These are top quality parts; very solid. Customer service is unsurpassed. They even matched prices on my order placed before the tax day sale. I made an error in ordering a drag link flip kit; they were quick to help me fix this too. There's peace of mind knowing these components are made in the USA. Thank you. 👍👍

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.
