Transform Your ZJ’s Suspension for Maximum Off-Road Performance

The CORE 4X4 Crawl Series Long Arm Upgrade Kit is a complete suspension overhaul for the 1993-1998 Jeep Grand Cherokee ZJ, delivering unparalleled ride quality, strength, and off-road capability. By eliminating the factory short-arm suspension and replacing it with precision-engineered long arms and high-strength mounting brackets, this kit dramatically improves axle stability, suspension cycling, traction, and handling. With extended suspension geometry, this kit allows your axles to cycle on a longer arc, resulting in a smoother ride, improved articulation, and optimized stance.

Whether you’re daily driving, rock crawling, or desert racing, this bolt-on system provides the durability and control needed to tackle any terrain.

Key Features and Benefits

  • Optimized Suspension Travel Geometry – Extends control arm mounting points, allowing axles to move on a longer suspension arc for a smoother ride and better traction. Eliminates axle bind and short-arm limitations, allowing for increased suspension articulation. Reduces body roll and improves high-speed stability while maintaining low-speed crawling capability.
  • Heavy-Duty DOM Tubing Construction – 1.75” OD DOM tubing for lower arms and 1.5” OD DOM tubing for upper arms, providing extreme durability and impact resistance. Double-threaded left- and right-hand adjusters allow for on-vehicle fine-tuning without removal. (Front upper control arms are fixed due to the U-bracket design.)
  • Precision-Cut and Bent 1/4” Steel Brackets – Replaces factory short-arm mounting brackets with reinforced, heavy-duty weld-on brackets designed for maximum strength and long-term performance. Integrated body mount relocation on rear brackets, ensuring proper clearance for full suspension travel.
  • Full Suspension Overhaul for Maximum Performance – Eliminates factory suspension limitations, providing significantly better ride quality, handling, and stance. Improves axle centering, caster, and pinion angles, ensuring proper drivetrain geometry and reducing stress on suspension components. Designed for heavy off-road use, daily driving, and load-bearing applications, making it the ultimate upgrade for any ZJ build.

Durable Powder Coating for Long-Lasting Protection

To ensure maximum durability and corrosion resistance, each component undergoes a two-stage powder coating process. The zinc primer base coat provides superior protection against rust, while the durable top coat—available in 10 color options—adds an extra layer of resilience and customization to match your Jeep’s build. Brackets are left raw to ensure proper welding and post-installation finishing.

Top notch company. Mechanic lost bolts that clamp upper control arms. Korby sent out spare bolts no charge. Best customer service I’ve come across in a long time. Only suspension brand I’ll ever use.

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control 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.

Ordered a control arm and track bar kit for my WJ from Core 4x4 on Monday 7/28 and received it today, Friday 8/1. Im not a state or two away, im in CT aka the other side of the country. Communication is phenominal, emails were responded too in an hour or less. Parts arrived well packed, not damaged, and are great quality for my needs. There arent many companies left that service customers as well as Core 4x4 and i wont hesitate to check them out again if i need something else. Well done!

I purchased the Jeep WJ control arms Camp series over a year ago. Very pleased and impressed. Easy installation and solid build. Bracket broke for rear upper control arm, they redesigned it to be more robust and sent me a new one with hardware, honoring their guarantee!

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.

Core 4x4 excels with precision and service and keeps nothing else higher in mind. Everyone I've met at the company is very honest and down to earth, 10/10 would recommend.

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.

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.
