This adapter bellhousing assembly is used to adapt the GM 4.3, V8 to the Jeep NV3550, 5 speed manual transmissions. The bellhousing kit includes a 356 T-6 aluminum bellhousing, universal dust cover plate, Jeep TJ master cylinder fitting, pilot bushing, special metric fitting hydraulic fitting (used with p/n 716213 slave cyl), throw-out arm, slave cylinder push rod, slave cylinder push rod end, ball pivot, fastening hardware, and adapter instructions.
Note: When using a 168th flywheel on your GM engine a gear reduction starter is required. We offer gear reduction starts (p/n 22-0001 & 22-0003).
Note: GM 4.3 V6 conversion applications with a 168th flywheel will experience header interference with the slave cylinder & throw-out arm. At that time, it is recommended that a muffler shop custom make an exhaust down pipe.
The NV3550 was used in the Jeep TJ Wranglers equipped with the 4.0L engine. The transmission case length is 24.00”. It has a 1-1/8”, 10 spline input shaft with a pilot tip of .750”. The output shaft is a flush 23 spline. The bolt pattern on the face of NV3550 looks identical to the AX15, except for a shift rail that protrudes from the top front of the NV3550.
