Maximize Your Jeep Grand Cherokee WK’s Suspension Performance

Upgrade your Jeep Grand Cherokee WK (2005-2010) with the Crawl Series Rear Control Arm Set, engineered for unmatched strength, durability, and off-road articulation. This set replaces factory components with heavy-duty adjustable control arms, ensuring precise axle alignment, optimized suspension geometry, and improved handling—essential for lifted vehicles navigating rough terrain.

Key Features and Benefits

  • Unmatched Strength Durability – Built from .313" wall DOM tubing, these control arms provide maximum resilience and longevity in extreme off-road conditions.
  • Full Suspension Adjustability – Designed to accommodate lifts from 0 to 6 inches, allowing for pinion angle correction, rear axle centering, and precise suspension tuning.
  • Rock Jock Johnny Joints for Maximum Flexibility – Featuring Johnny Joints at both ends, these control arms deliver superior articulation and responsiveness, providing smoother suspension movement over uneven terrain.
  • Precision-Engineered On-Vehicle Adjustability – Left and right-hand threaded adjusters allow fine-tuning without removal, making suspension modifications faster and easier.
  • Optional Bent Upper Control Arms for Additional Clearance – Need extra room around your gas tank skid plate? Opt for the bent rear upper control arms to optimize clearance and fitment.
  • Recommended Pairing – For a complete rear suspension upgrade, pair this kit with the Crawl Series Rear Track Bar (CRL-J-WK-RTB1) to fine-tune axle alignment and stability for maximum off-road performance.

Durable Two-Stage Powder Coating

Each control arm undergoes a two-stage powder coating process, featuring a corrosion-resistant zinc primer base coat and a top coat available in 10 colors. Ensures maximum protection against rust and wear while allowing you to customize the look of your suspension components.

Proudly Made in the USA

Manufactured in Orem, UT, our Crawl Series Rear Control Arm Set is built to top-tier American craftsmanship standards, ensuring superior reliability, precision, and strength.

First of I just want to say Great customer service korby Has helped me from the start and has not let me down! Reached out to him again today and he was able to warranty some parts out for me. As far as the quality of the parts.. excellent! The build quality is great. I can definitely tell a Difference from the cheap oem rear control arms to these and the pan hard bar. Color, From what I can tell it’s super durable been through a few mud holes on top of the daily road grime and after a quick wipe they still pop! Overall I recommend. Customer service is everything for me and it’s definitely there at Core 4x4.

I’m extremely impressed with Core 4x4. The quality of their parts is outstanding — everything feels solid, well‑built, and engineered with real attention to detail. Shipping was fast and everything arrived perfectly packaged. Their customer service is just as good as their products: responsive, helpful, and genuinely committed to making sure you get exactly what you need. Overall, a top‑tier experience. I’ll definitely be buying from them again. Specially thank you Mr. Linscomb from Core 4x4. Arturo M.

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.

Core 4x4 has outstanding products at a fair price and unmatched customer service. When you call Korby, it's like talking with a friend. Very cool and helpul! I ordered some custom control arms, but from the wrong product line and they were super cool about returning them and upgrading to a better "Crawl" series. Only charged the difference between the two products. They paid all the return shipping and sent the uprgaded arms super quick. It was only a couple days. Awesome!! I couldn't be happier with the transaction👍🏼 Also, these control arms are stout and take a beating. I run heck out my Jeep in the rocks and desert. No problems whatsoever. Thanks Core 4x4, ya'll are welcome at my campfire anytime! Jake T. Pleasant Hill, Or.

Have yet to get to try them but I bought some upper, and then later , lower control arms for my 03 rubicon. The pricing is very fair, so fair I was hesitant to even purchase. When the product came in I was happily mistaken. These are some beefy units with an incredible warranty! I’m very excited! I went with the “Camp”series as I mostly daily it. I have trouble with the shipping at times when I ordered but Corby is quick to notice things and help communicate the solution. Looking forward to buying more parts!
