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.

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.

Great company. Highly satisfied with Core 4x4 customer service. Had some bushings fall apart around 600 miles from home. Called and spoke with Korby Linscomb on Thursday, late in the afternoon. He was able to get my bushings sent across country overnight at a very reasonable rate. Had me up and running by Friday evening with enough time to enjoy the Great Smoky Mountain Jeep Invasion. Thanks Guys!

First off, I wish I knew about them sooner. The customer service is top tier. The response time is about 30 min no waiting 1-3 days to get a response. The parts are heavy-duty and look amazing. The packaging is perfect, I can't wait to hit some trails. Thanks Core4x4

Great products they sell, got a crawl series long arm kit for my xj and it has held up quite nice, they are beefy, and for what ever reason they fail it has a great warranty with a customer service to match, when someone asks what control arm kit to buy I always recommend core 4x4
