NV4500 GM Chevy Mainshaft 5th Gear 19 Tooth Early 6:34 Ratio 5 Speed Transmission

This is a reverse synchronizer assembly for the NV5600 Dodge diesel 6 speed transmission. These are now aftermarket replacements and do not include the spiral wound snap ring. The Dodge part number was 05012125AA.

This syncro kit fits all Dodge NV4500 transmissions and includes 6 rings. 3-4-5 and reverse rings are brass rather than the factory fiber lined style. We have found these to work better and last longer than the original design. 

This input shaft fits the G56 Dodge 6 speed manual transmission found behind the 5.9 Cummins diesel engine. It has 2 I.D. grooves on the shaft and 27 teeth on the gear.

This input shaft fits the NV4500 Dodge transmissions used behind the diesel or V10 gas engines. This is the larger 1 3/8″ clutch spline found on some aftermarket or factory 6 speed clutches.
