Experience top-notch off-road flexibility and admirable on-road manners with our Crawl Series Front Upper Control Arms. Tailored to be compatible with Jeep Gladiator JT model years 2020-Present, these arms are an ideal upgrade for those seeking the absolute best flexibility for off-road terrain while maintaining good road manners.
Our Front Upper Control Arms are constructed from 1.5″ OD DOM Tubing with a robust .313” wall thickness, providing a sturdy foundation for both on-road and off-road adventures. The design features the original Johnny Joints from Rock Jock 4×4 at the adjusting end and a U-bracket at the axle end, which attaches to the bushing already installed on factory axles. This configuration ensures smoother, more responsive movement and superior durability.
Our Front Upper Control Arms are designed with adjustability in mind. They enable precise alignment correction, help re-center your front axle, and accommodate lifts from 0 to 6 inches. For vehicles with lifts beyond 6 inches, please contact us for additional options and assistance. This means whether you’re riding at standard height or you’ve chosen to lift your vehicle up to 6 inches, these control arms offer a reliable, high-performance solution.
All of our control arms are subjected to a two-stage powder coating process for enhanced durability and corrosion resistance. This involves a base coat of zinc primer followed by a durable top coat in a color of your choice from our 10 color options.
Our Crawl Series represents American manufacturing at its finest. When you choose Crawl, you’re supporting American-made products and benefiting from our high-quality manufacturing standards.
Our Front Upper Control Arms are designed for convenient installation using factory hardware. For those dealing with rusted or stubborn bolts, we offer optional new Grade 8 hardware kits, available separately, to ensure a smooth installation process.
Choosing our Crawl Series Front Upper Control Arms means investing in superior off-road performance, enhanced on-road comfort, and the quality of American engineering. Upgrade your vehicle today and enjoy the benefits of advanced alignment and exceptional off-road flexibility.

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 anything red as this can prematurely deteriorate the internal components of the Johnny Joints and bushings used on our parts.
