Shop now for Synchronizer Parts specific to 2003-2005 4x4 and 4x2 Dodge Ram 2500 and 3500 trucks with either the Cummins Diesel or V10 Gas Engine and New Venture NV5600 6 Speed Manual Transmissions. Great selection. In stock. Quick shipping.
Early production (1999-early 2001) NV5600 transmissions and late production (2001.5-2005) ones use different, non-interchangeable synchronizer rings. We stock the Synchronizer Rings for later production units. If you need rings for an early NV5600 you better sit down before you read the Tech Note below because the news is very bad.
1999-2000, plus some early 2001 NV5600 transmissions used a unique synchronizer ring that was discontinued long before New Venture went belly up. To the best of my knowledge, no one currently makes rings for those early transmissions. What you need to do is replace the matching gear with a late model gear and purchase a late model ring for that gear. For instance, if your 5th and 6th synchros are out, you need to get a new style QU12001 Main Drive Gear (Input Shaft), QU12013 Mainshaft 6th gear, and 2 QU10408 Synchro Rings.
