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.

What's Included in the Kit

  • Crawl Series Front Lower Control Arms (CRL-J-JL-FL2)

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.

In Conclusion

Upgrade your Jeep Wrangler JL with the Crawl Series Front Lower Control Arms (CRL-J-JL-FL2) to correct factory caster deficiencies and improve both off-road flexibility and on-road stability.

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.

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

I contacted these guys on a Saturday through email and needed some control arms by the following weekend, Spence got back with me and told me he would make sure the order got shipped out on Monday, they got busy and wasn’t able to ship the package out so he got back with me that evening and upgraded my shipping for free and shipped out the next day, only because he told me he’d make sure I’d have them by the weekend! This company sticks to their word! The customer service from these guys are unmatched and they will have another lifetime customer here!

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!
