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.

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.

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.

CORE 4X4 Company produces/manufactures exceptional products. My rear upper and lower control arms and rear track bar were powder coated custom Fox “Shock Orange” for my 2024 Bronco Wildtrak. OEM looks minimal compared to the CORE 4X4 control arms. Plus they’re adjustable, serviceable and rebuildable. Shipment was very fast and packaging used custom foam wrapped around the arms and heavy duty boxes. Not even UPS could damage. Korby L. was great to work with and responded quickly with emails and product information. Great products. Great people from the State of Utah. All Made in the USA. 5 Stars!!!

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)

I just finished installing the Peak 2.0 Front Suspension system with the Core 4x4 Blue Tacoma Rear Suspension system on my 2024 TRD Offroad Premium Tacoma. The two upgraded suspension systems really made a difference in how the ride feels, whether we’re off-road or on the road. A big thank you to Korby and the team at Core 4x4 for their support and for getting the shipping sorted out so quickly!

I ordered a part for my 03 Jeep TJ and all I can say is wow! Korby at Core 4x4 is a total rockstar!! There was a glitch with my payment and within minutes, Korby reached out to me to get it fixed, then sent my receipt with the tracking number. I lost the number and reached out to him during the Holidays and got a rapid response with the number again. I can’t say enough about the customer service and the quality of parts. Thank you!!
