Product Description
ADVANCE ADAPTERS 712584 is the proven solution for converting your 1989-1993 Dodge Ram 5.9L Cummins from the factory Getrag G360 transmission to a heavy-duty Dodge NV4500 manual transmission. Designed specifically for first-generation Cummins trucks, this bellhousing adapter system allows owners to replace aging or hard-to-service Getrag transmissions with the far more common and durable NV4500 platform.
Manufactured from high-strength 356 T-6 aluminum, the 712584 bellhousing retains the factory Getrag slave cylinder, clutch arm, and release bearing, helping reduce conversion costs while simplifying installation. The kit includes the required pilot bushing, mounting hardware, crossmember support, and transfer case shifter bracket for 4WD applications. Advance Adapters engineered this system specifically for Cummins-powered Dodge trucks seeking improved reliability, serviceability, and long-term drivetrain support.

FAQ
Does the Advance Adapters 712584 allow me to replace my Getrag G360 with an NV4500?
Yes. The 712584 bellhousing is specifically engineered to adapt a Dodge heavy-duty NV4500 transmission to the Cummins Getrag adapter plate used on 1989-1993 Dodge Ram Cummins trucks.
Will I need a different slave cylinder?
No. This bellhousing is designed to retain the factory Getrag slave cylinder, clutch arm, and release bearing, reducing overall conversion cost.
Are modifications required during installation?
Yes. The NV4500 bearing retainer must be shortened to the specified length, and floorboard modifications are typically required due to the NV4500 shifter location.
Why convert from a Getrag G360 to an NV4500?
The NV4500 is significantly easier to source, service, and rebuild than the original Getrag transmission while offering improved long-term parts availability.
Is this kit made for Dodge diesel NV4500 transmissions?
Yes. The bellhousing is designed specifically for Dodge heavy-duty NV4500 applications used behind Cummins-powered trucks.
