Why Builders Choose CORE 4X4
Warranty facts, not marketing language.
Their “lifetime” language refers to their service model. Actual parts warranty: 1 year. Ours: lifetime.
Skip a maintenance interval? Their warranty voids. Ours doesn’t.
Clayton warrants their Johnny Joints for 90 days. We cover ours for life.
Maximize Your Jeep Grand Cherokee WK’s Suspension Performance
Upgrade your Jeep Grand Cherokee WK (2005-2010) with the Crawl Series Rear Control Arm Set, engineered for unmatched strength, durability, and off-road articulation.

What’s Included in the Kit?
- Crawl Series Rear Upper Control Arms (CRL-J-WK-RU2)
