Maximize Your Jeep Grand Cherokee WK’s Suspension Performance

Upgrade your Jeep Grand Cherokee WK (2005-2010) with the Crawl Series Rear Lower Control Arms, designed for unmatched strength, off-road articulation, and improved on-road comfort. These control arms provide superior durability over factory components, optimizing your vehicle’s suspension geometry, pinion angle, and rear axle alignment—essential for lifted vehicles.

Key Features and Benefits

  • Heavy-Duty DOM Tubing for Maximum Strength – Constructed from .313" wall DOM tubing, these control arms are engineered to withstand extreme off-road conditions.
  • Johnny Joints at Both Ends for Maximum Flexibility – Featuring Rock Jock Johnny Joints on both ends, these control arms provide unparalleled articulation and responsiveness, ensuring a smoother ride on and off the trail.
  • Fully Adjustable for Lifted Vehicles – Designed for 0 to 6 inches of lift, allowing for pinion angle correction, rear axle centering, and suspension tuning to reduce driveline vibrations and enhance handling.
  • On-Vehicle Adjustability – Left and right-hand threaded adjustment allows for fine-tuning without removing the control arms, making suspension modifications easier than ever.
  • Recommended Pairing – For optimal rear suspension performance, pair these control arms with the Crawl Series Rear Upper Control Arms (CRL-J-WK-RU2) to achieve a fully adjustable system capable of handling extreme lift modifications.

Two-Stage Powder Coating for Superior Protection

To ensure long-lasting durability and corrosion resistance, these control arms undergo a rigorous two-stage powder coating process. Zinc primer base coat – Provides advanced protection against rust and environmental elements. Durable top coat – Available in 10 custom color options to add a personalized finish that matches your Jeep’s style.

Proudly Made in the USA

Manufactured in Orem, UT, our Crawl Series Rear Lower Control Arms meet the highest American quality standards, ensuring superior reliability and craftsmanship.

  • Vehicle Fitment: Jeep Grand Cherokee WK 05-10 – Improves rear axle alignment, pinion angle, and suspension geometry for better drivability and off-road performance.

Korby was a great help with getting me a set of leaf springs for my Cherokee. Great customer service and an awesome product all made in the USA. Proud to support and rock their parts on my vehicle. 👍 …

First off: Korby, the gentleman that helped me decide on which kit to go with is EASILY the nicest, and most patient person I’ve dealt with, when ordering parts for this build. Second: the quality of the product is INSANE! These parts are so nicely fabricated, then powder coated for extra longevity, and they even offer an aluminum upgrade in some cases (which I went with, to save weight). Having said all of this, the most impressive thing was the lead time. These parts are build to order, and I literally ordered my suspension one week ago, today! Yes, they built, powder coated, packaged, shipped my suspension components (RAM 1500 Track rear trailing arm full set in 7075 aluminum, and front upper control arms), AND they arrived, all within a week! Granted, that I’m only one state away, but WOW!!! One week?! Amazing! So, in sort: excellent products, which arrived excellently packaged (no damage, an boxes not over-stuffed with heavy suspension parts; three boxes total, as opposed to one super heavy one…my back thanks you), super quickly, and customer service that ANY business would be envious of….so, if you’re in the market, absolutely go with Core 4X4!

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.

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!!!
