Enhance your off-road adventures with our JK Long Arm Kit, a premium upgrade designed for the Jeep Wrangler JK (model years 2007-2018). This kit combines high-quality materials with precision engineering to deliver outstanding performance and durability.
The standout feature of our 7075 aluminum control arms is their remarkable ‘memory’. This term refers to the material’s ability to return to its original shape after encountering impacts. When navigating rough terrains and hitting rocks or other obstacles, the control arms can withstand these forces without permanently bending. This exceptional resilience ensures your vehicle remains safe and reliable, significantly reducing the risk of being stranded off-road. With our control arms, you gain peace of mind, knowing your vehicle is equipped to handle the unpredictability of off-road challenges.
For optimal tire clearance and performance, full-width axles are recommended when utilizing these aluminum control arms. For Jeep Wrangler JKs with factory-sized axles, we offer an alternative in the form of steel control arms with appropriate bends to accommodate the axle size without compromising performance.
The JK Long Arm Kit is not just an upgrade; it’s a transformation. With its advanced materials and design, it’s an ideal choice for Jeep Wrangler JK owners looking to enhance their vehicle’s off-road capabilities. Equip your Jeep with this kit and experience a new level of performance and adventure.
Note: We can engrave our logo upon request, but standard arms will just get stickers.

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.
