Unmatched Off-Road Performance On-Road Comfort
Upgrade your Jeep Grand Cherokee ZJ with the Crawl Series Rear Long Arm Upgrade Kit, engineered to maximize suspension travel, axle stability, and ride quality. Designed for aggressive off-road performance and smooth highway driving, this kit transforms your ZJ’s suspension geometry, improving articulation and eliminating binding, even in extreme conditions.
Key Features and Benefits
- Heavy-Duty Construction – Built from 5/16” wall DOM tubing, these long arms deliver exceptional strength and articulation compared to factory and short-arm setups.
