Enhance your vehicle’s performance on and off the road with our Cruise Series Rear Upper Control Arms. Specifically designed for compatibility with Jeep Grand Cherokee WK model years 2005-2010, these control arms significantly outperform factory parts in terms of durability and strength.
Built with durable steel tubing, our Rear Upper Control Arms provide a sturdy foundation for all your off-road escapades. They are equipped with tapered polyurethane bushings on both ends, ensuring a more responsive and smoother ride than standard rubber bushings.
Our Rear Upper Control Arms are engineered for precise adjustability, facilitating accurate pinion angle correction and rear axle re-centering. They can easily accommodate lifts from 0 to 6 inches. When used with our Rear Lower Control Arms, they ensure full alignment correction and recentering of the rear axle. This combo enhances handling, reduces wear on tires and suspension, and provides flexibility for future lift modifications, proving to be a crucial part of your suspension upgrades. For lifts beyond 6 inches, please contact us for additional options.
We use a two-stage powder coating process for all our control arms. This process begins with a zinc primer base coat that provides superior corrosion resistance, followed by a durable top coat. You can select your preferred color from our range of 10 options, adding a personal touch to your Cruise Series Rear Upper Control Arms.
Every component of our Cruise Series is meticulously manufactured in our facility in Orem, UT. We take pride in sourcing our materials locally and maintaining complete control over the manufacturing process to ensure our products meet the highest quality standards.
The installation of our Rear Upper Control Arms can be easily accomplished using factory hardware. For those dealing with rusted or stubborn bolts, we also offer optional new Grade 8 hardware kits, available separately, to facilitate a smoother installation process.
Choosing our Cruise Series Rear Upper Control Arms means opting for impressive on-road comfort, fantastic off-road durability, and the robustness of American engineering. Invest in your vehicle with our control arms today for a notably improved driving experience.

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.
