Unmatched Strength and Flexibility

Upgrade your Jeep Grand Cherokee WJ (1999-2004) with the Crawl Series Front Lower Control Arms, delivering extreme durability, superior articulation, and precise alignment correction. Designed for off-road enthusiasts and daily drivers alike, these heavy-duty control arms provide exceptional strength and flexibility while maintaining outstanding on-road performance.

Key Features and Benefits

  • Heavy-Duty DOM Tubing for Maximum Strength – Built from 1.75” OD 5/16” wall DOM Tubing, these control arms far surpass factory components in durability, ensuring your suspension can handle intense off-road conditions and everyday driving with ease.
  • Johnny Joints for Superior Articulation – Equipped with RockJock Johnny Joints at both ends, these arms provide unmatched flexibility and movement, allowing your suspension to perform optimally even under extreme articulation. This means smoother, more controlled handling on rough trails without binding.
  • Adjustability for Lifts from 0 to 6 Inches – Designed to work with stock height and lifted vehicles, these control arms allow for precise axle centering and alignment correction, improving handling and reducing premature wear on suspension components.
  • Pair with Front Upper Control Arms for a Complete Solution – For maximum performance and alignment control, we recommend pairing these with the Crawl Series Front Upper Control Arms (CRL-J-WJ-FU2) to fully optimize front-end suspension geometry for superior handling on and off the road.

Two-Stage Powder Coating

Each control arm undergoes a two-stage powder coating process for extreme durability and corrosion resistance.

  • Zinc primer base coat provides a strong barrier against rust.
  • Durable top coat, available in 10 colors, ensures a custom look and lasting protection.

Proudly Made in the USA

Manufactured in Orem, UT, our Crawl Series Control Arms represent the highest standards of American craftsmanship and engineering. We oversee the entire production process to ensure superior quality and long-lasting performance.

Optional Hardware Upgrade

Designed as a direct bolt-on replacement, these control arms reuse factory hardware for a hassle-free installation. Optional Grade 8 hardware kits are available separately for those dealing with rusted or stubborn bolts.

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!

I meant to put this reviewing about a year ago now, but ever since I’ve had the core 4 x 4, upper and lower control arms on my 2017 ram 1500, they have worked flawlessly leave been on many offering chips, and I’ll definitely be buying new accessories from them in the future and their new upper control arms that they’re offering for all of the ram trucks. Fantastic customer service fantastic health very automotive, off-road, friendly, and any aftermarket thing for your truck or SUV that they currently have!

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

I don’t write reviews often, but Core 4x4 absolutely earned this one. I recently ordered leaf spring mounts and realized after the fact that I messed up my order. Totally my mistake. Instead of giving me the runaround or pointing at a return policy, Core 4x4 emailed me back and forth, worked through exactly what I was doing with my build, and made sure I ended up with the correct parts. That kind of customer service is rare these days — especially in the off-road world where a lot of companies stop caring once the order is placed. The parts themselves are exactly what you hope for: solid, well-made, confidence-inspiring hardware that looks like it belongs under a vehicle that actually gets used. You can tell these are designed by people who understand suspension geometry and real-world abuse, not just CAD screenshots. Mistakes happen — especially on custom or modified builds — and Core 4x4 handled mine like pros. Fast responses, clear communication, and a genuine effort to help me get it right. If you’re on the fence: don’t be. Core 4x4 is the kind of company you want backing your build — the kind that treats customers like fellow enthusiasts, not order numbers.

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.

First off amazing products. I got a set of adjustable control arms for my XJ and it is so nice to be able to dial in caster and pinion angles. A quick call and I was able to purchase an adjustable track.
