Elevate your off-road journey and on-road comfort with our Camp Series Rear Upper Control Arms. Specifically designed to be compatible with Jeep Grand Cherokee WK model years 2005-2010, this pair of Rear Uppers (CMP-J-WK-RU2) assures superior durability and exceptional strength compared to both factory components and rival aftermarket solutions.
Our Rear Upper Control Arms are constructed from robust 5/16″ wall thick DOM tubing, ensuring outstanding durability. The design features our unique tapered polyurethane bushings and Rock Jock Johnny Joints at the adjusting ends. These enhancements provide greater stability and responsiveness for your vehicle’s suspension, delivering a performance that surpasses other offerings on the market.
Our rear upper control arms are crucial for preserving your vehicle’s drivability after lifting it. They are specifically crafted to adjust for lifts between 0 and 6 inches, working seamlessly to correct the pinion angle and recenter your vehicle’s rear axle. Pairing these with our Camp Series Rear Lower Control Arms offers a comprehensive suspension solution that optimizes vehicle handling, minimizes wear on your tires and suspension, and accommodates future lift modifications. Furthermore, we offer an optional bend in the control arms for additional clearance around the gas tank skid plate, a critical consideration for this vehicle.
All components in the Camp Series undergo a rigorous two-stage powder coating process, enhancing their durability and aesthetic appeal. Starting with a zinc primer base coat for excellent corrosion resistance, we follow up with a top coat of your choice from our selection of 10 vibrant colors. This ensures that your vehicle’s upgraded components not only perform exceptionally but also look great.
Our Camp Series components are proudly made in our facility in Orem, UT. By sourcing raw materials locally and maintaining full control over the manufacturing process, we guarantee products that meet the highest quality standards while keeping prices competitive.
Our Rear Upper Control Arms can be conveniently installed using factory hardware. If anything additional is needed, we’ve got you covered – it’s included in the package. We also offer new Grade 8 hardware kits as an optional upgrade, available for separate purchase, ensuring a smooth and straightforward installation process.
Choosing our Camp Series Rear Upper Control Arms means you’re investing in superior off-road performance, unmatched on-road comfort, and the excellence of American engineering. Upgrade your vehicle today to experience the benefits of precise alignment correction and exceptional trail performance.

Our product lines are designed to offer the absolute most value for your budget. Not every build is the same and we understand that. Our series differ mostly in the components used in the construction of the parts. Our Cruise and Town Series utilizes our high grade flex poly bushings at both ends of the arm, this has proven to be a smooth riding easy to maintain and replace bushing that we absolutely love. Our Camp and Trail Series utilizes 5/16″ wall DOM tubing and incorporates a flexible Johnny Joint at the adjusting end, this series has been our most popular series for all around use, great for daily drivers that want to tear up the trails as well. Our Crawl, Tow, and Track Series utilizes the same 5/16″ wall DOM tubing, but features Johnny Joints at both ends. This series gives you the absolute most out of your suspension. This is great for heavy towing/hauling and extreme off-roading. Also, if the component is straight in these series we will machine these left and right hand threaded for easy adjustment on the vehicle!
We are constantly expanding our product lines to include complete kits, if you don’t see something on the site for your vehicle, reach out to our sales team and we can put something together for you.
Our two main sizes of jam nuts require an1-1/2″ wrench or an 1-5/8″ wrench. Generally speaking the 1-5/8″ jam nuts are used on our lower control arms and the 1-1/2″ jam nuts on our upper control arms and track bars. There are some exceptions, but we do offer a crow’s foot that has both sizes.
Any non-synthetic moly based grease is safe on our products, avoid anything red as this can prematurely deteriorate the internal components of the Johnny Joints and bushings used on our parts.
