Unmatched Off-Road Flexibility On-Road Stability

Upgrade your Toyota 4Runner (2003-2024) with the Crawl Series Rear Control Arms Set, engineered to provide superior strength, articulation, and long-lasting durability. This complete set includes two upper control arms (CRL-T-4R-03-RU2) and two lower control arms (CRL-T-4R-03-RL2), delivering maximum axle control, improved suspension geometry, and unmatched performance for both off-road terrain and highway driving.

Key Features and Benefits

  • Heavy-Duty DOM Tubing Construction – Built from 1.75” OD DOM Tubing with a 5/16” wall thickness, these control arms provide exceptional strength and durability, outperforming factory and aftermarket alternatives.
  • Johnny Joints for Maximum Flexibility – Equipped with Johnny Joints at both ends, these arms allow incredible articulation, reducing suspension binding and improving off-road handling.
  • Left- and Right-Hand Threaded Adjustability – Designed for on-vehicle fine-tuning, these control arms allow for precise axle re-centering and pinion angle adjustments without needing removal.
  • Fully Adjustable for Lifted Vehicles – Accommodates 0 to 6 inches of lift, ensuring optimal axle positioning and suspension geometry correction. For lifts beyond 6 inches, contact us for additional solutions.
  • Recommended Pairing – Pair with the Crawl Series Rear Track Bar (CRL-T-4R-03-RTB1) for a complete rear-end suspension solution, giving you absolute control over axle centering, pinion angles, and suspension geometry.

Two-Stage Powder Coating for Maximum Protection

  • To ensure long-lasting durability and corrosion resistance, all control arms undergo a two-stage powder coating process: Zinc primer base coat for superior rust prevention. Durable top coat available in 10 custom colors for added protection and personalization.

I recently ordered a set of control arms from Core 4x4, and the entire experience was absolutely top-notch from start to finish. The ordering process was smooth, the parts arrived quickly, and the control arms themselves are extremely high quality—solid construction, great finish, and clearly built to last. I also want to give a special shout-out to Korby, the guy I spoke with during the process. His customer service was amazing. He went above and beyond to make sure I got exactly what I needed, answered all my questions, and made the whole experience stress-free. You don’t see service like that very often these days. If you’re looking for high-quality suspension components backed by truly exceptional customer service, I highly recommend Core 4x4. I’ll definitely be buying from them again.

Great company, who worked with me on shipping parts, to arrive in time for a show, when I explained my concern of possibly not getting the control arms in time. Quality is amazing on the part, affordable price for what you get, and the powdercoat is top notch, not a single issue with this product, would buy again.

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.

Got the CAMP version of adjustable control arms and track bars for our 03 TJ with a 3” lift and 33x10.5 KO 2’s. Super beefy bars, great fit and adjustability. Friendly advice and support from Korby at CORE 4X4. Good follow up as well. The ride quality is great as well as the handling. I think it all looks pretty good as well.

The folks at Core 4X4 are always wonderful to deal with. They explain your options and never pressure or rush things. The quality of the Core Control Arms is top shelf, especially if your goal is to stop wheel hop. I recommend Core 4x4 without reservation ! ! !

I ordered the jeep xj long arm lift kit. Control arms showed up first they turned out amazing!! Had some issues with the powder coating on the cross member and sent korby and the team at core4x4 an email. They got right on making me another cross member and sending it out. I appreciate all the help they've given me along the way. Very fast response thru emails. Build quality seems to be pretty dang nice!! Can't wait to install it and enjoy it!

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!
