Upgrade your Toyota 4Runner (2003-Present) 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.

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 couldn't have been more excited for the initial unboxing of these new Core 4x4 UCA's! They appear to be so well built and just a true quality product. Installation was a breeze and the initial testing with the forklift appears to have given me some additional flex with less binding on the rest of the components now that the geometry is back properly aligned. Time will tell how they hold up on my near future off-road adventures but I don't have any doubt that they are up to the task!

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 :) .

Excellent quality product and service. My l lower control arms broke and within the same day core 4x4 hooked me up with tier 2 arms and with the color I wanted. My Jeep rides better and has been solid for several months so far. 10/10 would recommend their products to anyone.

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 ! ! !

Small business, family owned, made in the USA, lifetime warranty. Purchased Tier 3 control arms and rear track bar for a 2006 Jeep LJ. Simple website and easy to contact over phone and email. I had some technical questions and they were happy to answer them. They allow local pickup and were built to order same week. The order was wrapped and ready when I walked in and even gave a tour of the shop. They abrasive blast all raw materials to achieve a better surface profile for powdercoat to adhere and create a smooth, durable finish. I also noticed several CNC machines and a robotic welder they use for all their parts. A small outfit with a robotic welder? Their concern for quality is obvious and it shows in the parts they make. Very impressed. Happy to do business with these guys.
