Experience the ultimate off-road flexibility with the Crawl Series Rear Lower Control Arms. Designed specifically to be compatible with Jeep Gladiator JT model years 2020-present, these control arms effortlessly blend remarkable on-road manners with uncompromising off-road prowess. Engineered to outperform standard factory parts, they deliver durability and performance that are second to none.
Meticulously constructed from robust 1.75” OD DOM Tubing with a .313” wall thickness, our Rear Lower Control Arms demonstrate a level of durability that surpasses most competitors. They incorporate original Johnny Joints at both ends, ensuring a perfect blend of flexibility and strength, which are key to enduring the rigors of off-road use.
Our Rear Lower Control Arms offer exceptional adjustability, with left and right-handed threads that facilitate easy modification of your wheel center while installed. This enables precise alignment correction and accommodates lift heights ranging from 0 to 6 inches. For optimal results, we recommend using our adjustable upper control arms. This combination provides a complete solution for accurately re-centering the axle and fine-tuning the pinion angle. For vehicles with lifts beyond 6 inches, additional options and guidance are available on request.
To ensure maximum durability and resistance against corrosion, all our control arms undergo a rigorous two-stage powder coating process. We start with a robust zinc primer base that prepares the metal for the final layer—a resilient top coat in your choice of color. This double-protective layer not only withstands the harshest conditions but also adds a personalized touch to your vehicle.
Choosing our Crawl Series is a testament to the quality of American craftsmanship. Each component in this series represents a fusion of engineering prowess and manufacturing excellence, embodying the high standards that are inherent in American-made products. When you invest in our Crawl Series, you are supporting local industries and embracing the exceptional quality of US manufacturing.
Installation is designed to be straightforward using existing factory hardware. We understand that certain conditions may require additional measures, and for this reason, we offer optional Grade 8 hardware kits—available separately—for those dealing with stubborn or rusted bolts. This ensures a smooth installation process and a secure fit.
Choosing the Crawl Series Rear Lower Control Arms means providing your vehicle with the strength, durability, and off-road flexibility it deserves. Make the upgrade today and witness the transformative impact on your off-road performance firsthand.

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.
