ADAPTER PACKAGES & INDIVIDUAL COMPONENTS
FOR
JEEP VEHICLES
We offer complete adapter packages for the most common Jeep engine and transmission swaps along with the most common transmission retrofits.
If we do not show a transmission package specifically for your application, more than likely we offer the individual components to convert your
vehicle.
The components in the packages that we do offer can also be purchased separately. In the applications to follow,
we have listed the transmission package(s) plus the individual components, and any optional or related items that we offer. Also noted are some
of the modifications you may be required to perform.
We currently offer rebuilt NV4500 transmissions. The GM 4WD NV4500 can be purchased under Part No. 26-0007R , the Dodge 4WD NV4500
under Part No. 26-0029R , and our custom built transmission with the Dodge 29 spline output shaft and the GM inputshaft is sold uner Part Number
26-0029RGM . If you wish to obtain your own transmission, please refer to the GM and Dodge identification charts for both current and past
OEM part numbers.
JEEPS 1941-1979 (Dana 18/20 - Long wheel-based vehicles only):
In order to adapt a NV4500 to these transfer cases, the transmission must be a GM 4WD NV4500 . The spud shaft we manufacture
couples to the 31 spline portion of the GM output shaft. This 31 spline area is located under the vibration damper or sleeve on this
output shaft. The stock output shaft must be cut to the proper stickout length of 4.498” to couple to our spud shaft. The stock GM
tailhousing will not be reused, since these kits provide a new tailhousing adapter. The bearing retainer provided in the transfer
case kit is ONLY for large hole transfer cases. If you have a small hole transfer case, please contact us for more information.
The transfer case linkage will need to be modified in order to fit alongside the large 5 speed transmission case. The Dana 18/
20 used several different shift linkages, some requiring more modifications than others. Due to the length of the transmission,
driveline modifications will almost always be required. A 1” to 2” body lift is usually required to obtain proper tunnel clearance.
These kits are not compatible in short wheel-based vehicles such as the CJ5 models. The only exception to this would be to use
a 4 cylinder or V6 engine. The engine would then need to sit to the very forward position of the engine compartment. Even so, when
we installed a NV4500 into a 1966 CJ5 with a V6, the rear driveshaft was still very short.
