Optimize the rear axle of your Jeep Wrangler JL (model years 2018-present) with our Rear Long Arm Kit. This kit is specifically designed to enhance the durability and performance of your vehicle’s rear suspension, making it ideal for off-road enthusiasts.
The 7075 aluminum rear control arms feature an exceptional ‘memory’ attribute. This allows them to revert to their original shape after impacts, providing resilience against challenging terrains and maintaining the integrity of your vehicle’s rear suspension.
Our Rear Long Arm Kit transforms the rear axle of your Jeep Wrangler JL, preparing it for the toughest off-road conditions. Upgrade to this kit and experience a significant improvement in handling, stability, and overall off-road 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.
