Solve the Jeep JL’s Caster Deficiency for Superior Drivability

The Crawl Series Front Lower Control Arms are a must-have upgrade for Jeep Wrangler JL (2018-Present) models, addressing the factory issue of insufficient caster. Designed to improve alignment and drivability, especially for lifts from 0 to 3 inches, these control arms reduce symptoms like flighty steering, road rut tracking, and unstable handling.

For lifts over 3 inches, pairing with our Crawl Series Front Upper Control Arms ensures precise alignment and enhanced performance.

Key Features and Benefits

  • Corrects Caster for Superior Handling – Optimized for lifts from 0 to 6 inches, these control arms move the front axle forward and increase caster, resolving flighty steering and road rut tracking for dramatically improved drivability.
  • Built for Strength and Durability – Constructed from heavy-duty 1.75” OD DOM Tubing with a 5/16” wall thickness, these control arms deliver unmatched strength and longevity for extreme off-road use.
  • Johnny Joints for Maximum Articulation – Equipped with premium Johnny Joints at both ends, these control arms provide bind-free movement, delivering exceptional off-road flexibility and smoother on-road performance.
  • Full Adjustability for Lifted Vehicles – Adjustable to accommodate lifts from 0 to 6 inches, these control arms allow precise alignment correction and axle re-centering. For lifts over 3 inches, pairing with Crawl Series Front Upper Control Arms ensures optimal suspension geometry.

Two-Stage Powder Coating

Every control arm undergoes a two-stage powder coating process for superior durability and corrosion resistance. Zinc primer base provides a strong foundation against rust. Durable top coat, available in 10 color options, adds an additional layer of protection and customization.

Made in the USA

Proudly designed and manufactured in Orem, UT, the Crawl Series Front Lower Control Arms reflect CORE 4X4’s dedication to American craftsmanship. By sourcing materials locally and maintaining stringent manufacturing standards, we deliver premium-quality products you can trust.

Optional Hardware Upgrade

Installing the Crawl Series Front Lower Control Arms is straightforward using factory hardware. Optional Grade 8 hardware kits are available for those dealing with rusted or stubborn bolts, ensuring a smooth and hassle-free installation process.

Designed for lifts from 0 to 3 inches—and compatible with Crawl Series Front Upper Control Arms for larger lifts—these control arms provide unmatched strength, adjustability, and drivability.

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.

I have recently come to know Core 4x4 when I purchased a Jeep XJ and was looking for a place that had dedicated XJ suspension and components. Here is what makes them different than most other shops. All of their components are top shelf quality and they back it up if you break any of it. I was able to see their shop when I picked up an order locally and was impressed with their attention to detail and how they assemble and powder coat each part. I had an issue with a shackle and needed the threaded shaft to be shorter. I called in and talked to Kaden and he told me to come by and they would shorten it for me. When I got there, Kaden and Spencer (the owner) met me and talked about options and proceeded to make the right adjustments to fit my XJ. Told me if anything changes in the future and I need additional length, they would take care of me. So what really sets them apart from others is their Customer Service. Try calling in to any other Jeep suspension or part shop and see how they treat you. Been there - done that. Will continue to do business with Core and their team. Getting that kind of service for just a shackle has me thinking I may need to replace my JT components with Core's. Thanks Guys for being helpful good humans!

I've been having trouble with the track bar (on my 2nd gen Dodge) since I installed the 3rd gen Synergy adapter bracket and a 3rd gen stock bar.. oddly, they call it a '3rd gen bracket' and the stock 3rd gen bar doesn't quite fit, making contact with the bracket. I had attempted to clearance the bracket but it was still making contact and I could feel it over large bumps. I reached out to a lot of companies, but Core 4x4 offered to make a custom bar for the application with adjustability and dual Johnny joints. The first pass on it didn't work but they sent me out another passenger side end that made it fit incredibly well. This was all done solely over email/descriptions/pictures/measurements. Bar is super high quality and heavy duty, made in the US by a family owned company and carries a lifetime warranty. The customer service was responsive and superb, and the price was a lot less than I expected.

Outstanding experience! I asked Core to build me a set of custom control arms that were larger/heavier than they normally build. They gladly accepted the challenge and turned out an expertly crafted and super strong product ahead of schedule. Fit and finish are excellent. Spence and Cameron were a pleasure to work with every step of the way. And all of this for a very reasonable price. I highly recommend these guys!

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.
