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.

I have a 2016 RAM 1500 Crew Cab and I replaced the rear upper and lower control arms also the pan hard track bar and also the sway bar and links for the rear with all I had the articulating bushings. The vehicle now has no body role. They are absolutely incredible if you get the control arms you gotta get the CORE 4 x 4sway bar end links don’t don’t try and be cheap and get Moog or something else you got to get articulating bushings get the core 4 x 4 ones they are the best. My truck drives now through the canyons like a BMW. I have Fox high-performance shocks on there as well with all the CORE 4 x 4 suspension parts and they are amazing. Well worth the money I would highly recommend anybody thinking about CORE 4 x 4 go with CORE 4X4 and if you can go with their articulating bushings, they’re unbelievable drives better now than my Escalades. Well planted no body role and smooth on the Highway unbelievable the difference they all made!! THANKS AGAIN CORE 4x4!!!!

Not sure where to start, Products or Service or Warranty. Products: I found Core4x4 through a very respected YouTuber in the Jeeping community. I purchased an entire set of Core4x4 Control Arms three years ago and have beat the daylights out of them and they are still in great condition. Now, I purchased another Jeep, this time for my daughter and bought yet another set of Control Arms because I know that these things can take a beating and stand up to it. I plan on replacing more parts on this TJ and my JL and will continue to buy from Core4x4. Service: This isn't some huge name conglomerate that treats you like you're just another customer. They are quick with responses and will always make things right should something be a problem. Oh and the quickness in which they ship their products is unmatched. I bought these CAs for my TJ on Thursday, I received them on Monday. Most other manufacturers will tell you weeks, they had them to me in 2 shipping days. Warranty: Seriously, a lifetime warranty? Yes please. Nothing more to say. I can't say enough about how great of a company this is. I've even spoken to the owner through email a few years back on some questions that I had. Support small American built businesses. P.S. Core 4x4, feel free to make me an ambassador and send me some swag :) .

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.

The whole process was quick and painless. The products are top tier and when I reached out them for package update info, Korby Linscomb was very responsive, and got me the answers I needed the same day. Even when I emailed back to some additional info, he sent what I was looking for that same day. I love core 4x4 and will be giving them my business from now on.

I ordered a part for my 03 Jeep TJ and all I can say is wow! Korby at Core 4x4 is a total rockstar!! There was a glitch with my payment and within minutes, Korby reached out to me to get it fixed, then sent my receipt with the tracking number. I lost the number and reached out to him during the Holidays and got a rapid response with the number again. I can’t say enough about the customer service and the quality of parts. Thank you!!

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!
