Crown Automotive is the premiere manufacturer and distributor of quality replacement parts for Jeep CJ, Wrangler, Cherokee, Grand Cherokee, Liberty, and Commander. Because we know that Jeeps are driven harder than most other vehicles, we emphasize offering only quality parts. In fact, we test parts on Jeeps before distributing them to our dealers to insure that they meet our standards for quality. Crown also supports its entire line with a 12 month/12, 000 mile .
