Part #: 4504348
Crown Automotive is the premiere manufacturer and distributor of quality replacement parts for Jeep(R) CJ(TM), Wrangler(TM), Cherokee(TM), Grand Cherokee(TM), Liberty(TM), and Commander(TM). With over 8,000 different parts in stock for Jeep(R) vehicles from 1942 on up, Crown has the largest stock of replacement parts for Jeep(R) vehicles, including factory-discontinued parts. In fact, many of the older Jeeps are still on (and off) the road thanks to Crown parts. The Crown line consists of axle, body, brake, clutch, cooling, driveline, electrical, engine, exhaust, fuel, steering, suspension, transmission and transfer case components. Crown Automotive also offers an exclusive line of component kits and accessory products. 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 warranty to insure our dealers and their customers of our commitment to offering quality parts.
