Product Details

Maximize Your Jeep Grand Cherokee WJ’s Suspension Performance with the Camp Series Front Control Arms Set (1999-2004)

Take your Jeep Grand Cherokee WJ’s suspension to the next level with the Camp Series Front Control Arms Set. This two-piece set includes Front Upper Control Arms (CMP-J-WJ-FU2) and Front Lower Control Arms (CMP-J-WJ-FL2), offering a comprehensive upgrade for your vehicle’s front suspension system. Engineered for exceptional strength, adjustability, and durability, this set provides superior performance both on-road and off-road.

What’s Included:

  • Front Upper Control Arms (CMP-J-WJ-FU2)
  • Front Lower Control Arms (CMP-J-WJ-FL2)
  • Mounting Spacers (4)

Built for Strength and Flexibility

Constructed with DOM Tubing featuring a .313" wall thickness, the Camp Series Front Control Arms are built to handle even the toughest terrains. Each arm incorporates a tapered polyurethane bushing at the fixed end for reduced vibration and improved ride quality, and a Johnny Joint at the adjustable end for superior articulation and flexibility during off-road adventures.

Adjustability for Precise Alignment

Fully adjustable to accommodate lifts from 0 to 6 inches, these control arms allow you to dial in perfect suspension geometry. They are essential for correcting caster angles, recentering the front axle, and maintaining proper alignment—enhancing handling, safety, and tire longevity. For lifts beyond 6 inches, additional solutions are available upon request.

Durable Two-Stage Powder Coating

Our two-stage powder coating process ensures lasting protection and a premium finish. Zinc primer base coat provides corrosion resistance. Durable top coat—available in 10 color options—lets you customize the appearance of your control arms to match your vehicle’s style.

Proudly Made in the USA

Manufactured at our facility in Orem, UT, the Camp Series Front Control Arms Set reflects the highest standards of American craftsmanship. By sourcing local materials and overseeing every step of the production process, we deliver components you can trust for durability and performance.

Optional Hardware Upgrade

The Camp Series Front Control Arms are designed for straightforward installation, utilizing your Jeep’s factory hardware and the included spacers for a secure fit. Optional Grade 8 hardware kits are available for rusted or stubborn bolts to ensure a smooth installation experience.


  • Vehicle Fitment: Jeep Grand Cherokee WJ 99+04 – Designed to correct suspension geometry, enhance front axle alignment, and improve overall handling.

  • CORE Advantage: Replaces weak factory control arms with high-strength adjustable components, improving steering response, ride quality, and off-road articulation.

  • Adjustability: Adjustable from 0 to 6 inches of lift, allowing for precise caster correction, axle re-centering, and optimized suspension geometry.

  • Construction: Heavy-duty DOM tubing with a 5/16” wall thickness, featuring a Johnny Joint at the adjustable end for articulation and a tapered polyurethane bushing at the fixed end for vibration absorption. Includes four mounting spacers for a secure fit.

  • 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.

Awesome product and service! I even got some of their swag because it looked pretty darn good. I will definitely be going back and would suggest this business to others looking for quality control arms. Buy local!

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.

First off amazing products. I got a set of adjustable control arms for my XJ and it is so nice to be able to dial in caster and pinion angles. A quick call and I was able to purchase an adjustable track.

I broke a grease fitting off in my end link. I thought I was going to have to buy a new one. Reached out to Core 4x4 and wham! bam! They fixed it and sent it back with 2 day shipping. Got it a day early even. If they couldn't fix it they were going to send me a new one. Now that's customer service! They are now a permanent part of my garage. Thank you Core 4x4!

Finally a company with a great product and customer service to match. I changed my order last minute from short arms to long arms. The lift is extremely well built. Korbey was awesome! Highly recommend Core 4x4
