Product Description
This Dorman OE FIX 4WD disconnect gear eliminates the need to buy an entire differential or use salvage yard parts to repair a failed gear for certain 4WD Ram 1500 and Classic pickups. The OE disconnect gear is not available as an individual part, and the only way to get a new one is to order a complete new front differential assembly or go to a salvage yard. This OE FIX gear directly replaces a failed gear, restoring function to the truck's front differential.
- Saves expense - designed to help enable a cost-effective repair vs. buying an entire new front differential assembly when only the 4WD disconnect gear needs to be replaced
- Direct replacement - this 4WD disconnect gear is designed to match the fit, function and performance of the original equipment on specified Ram vehicles and engineered to help restore axle function
- Durable construction - designed and manufactured to strict specifications for reliable performance
- Trustworthy quality - backed by a team of product experts in the United States and more than a century of automotive experience
