Enhance your off-road journey and on-road comfort with our Crawl Series Rear Control Arm Set. Specifically designed to be compatible with Jeep Grand Cherokee WK model years 2005-2010, this set includes our CRL-J-WK-RU2 (Pair of Rear Uppers) and CRL-J-WK-RL2 (Pair of Rear Lowers). Providing significant enhancements over both factory components and other aftermarket alternatives, this product assures increased durability and superior strength.
Constructed from robust 5/16″ wall thick DOM tubing, our Rear Control Arm Set assures maximum durability. The design features Rock Jock Johnny Joints at both ends of the Rear Uppers and Rear Lowers, enhancing the stability and responsiveness of your vehicle’s suspension. The unique ability to left and right hand thread the control arms for adjustability while installed on the vehicle further enhances its superiority and ensures a performance that surpasses other aftermarket options.
Our rear control arm set is essential for maintaining excellent drivability after lifting your vehicle. Specifically crafted to adjust for lifts from 0 to 6 inches, these control arms work harmoniously to correct pinion angle and recenter your vehicle’s rear axle. Their performance is designed to optimize vehicle handling and minimize unnecessary wear on your tires and suspension. 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 our Crawl Series undergo a rigorous two-stage powder coating process, involving a corrosion resitant zinc primer and a top coat of 10 available colors enhancing their durability and aesthetic appeal. This ensures that your vehicle’s upgraded components not only perform exceptionally but also look great.
All of our Crawl Series components are proudly made in our Orem, UT facility. 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 Control Arm Set can be conveniently installed using factory hardware. If anything additional is needed, we’ve got you covered – it’s included in the package. For those dealing with rusted or stubborn bolts, 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 Crawl Series Rear Control Arm Set means opting for superior off-road performance, unmatched on-road comfort, and the robustness of American engineering. Upgrade your off-road experience today and 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 lithium greases and anything red as this can prematurely deteriorate the internal components of the Johnny Joints and bushings used on our parts.
