Our Camp Series Rear Upper Control Arms offer a compelling upgrade to your vehicle, compatible with Jeep Wrangler JL model years 2018-Present. These arms significantly improve on-road comfort while enhancing off-road flexibility and durability – a major upgrade over standard factory parts.
Constructed from robust 1.5” OD DOM Tubing with .313” wall thickness, our Rear Upper Control Arms are engineered to outperform most of our competitors. The Johnny Joint at the adjusting end and our unique tapered polyurethane bushing at the axle end combine to provide superior strength and performance.
Designed for precise alignment, our Rear Upper Control Arms can accommodate lifts from 0 to 6 inches. This enables re-centering of your rear axle and allows for the perfect alignment of your vehicle (when used in conjunction with our rear lower control arms) . For lifts beyond 6 inches, please contact us for additional options and assistance.
Each control arm undergoes a two-stage powder coating process: starting with a zinc primer base for excellent corrosion resistance, followed by a top coat of your color choice from our selection of 10 colors. This ensures durability and the aesthetic appeal of your control arms.
Our Camp Series is proudly made in our facility in Orem, UT. We source our materials locally and have complete control over the manufacturing process, ensuring that our products meet the highest quality standards.
Our Rear Upper Control Arms can be conveniently installed using factory hardware. We also offer optional new Grade 8 hardware kits, available separately, to assist with rusted or stubborn bolts.
Choosing our Camp Series Rear Upper Control Arms means opting for superior comfort, flexibility, and the quality of American engineering. Upgrade your vehicle today and experience the difference.

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.
