One of the most exciting things that has been happening at Novak is the introduction of a supreme way for us to assist our customers in performing a Jeep powertrain conversion.

By integrating and providing the entire Jeep's new powertrain, we shoulder the most significant technical portions of the conversion process.

We can provide:

Every powertrain we build is fully assembled on a test stand and then we run it, testing the operation of all systems, including the computer. Once satisfied, we then detach the assembly from the stand and lower it into a crate for shipment.

A Gen III Powertrain

The customer can then place the full powertrain into the Jeep chassis and weld/bolt on the provided frame brackets, connect a minimal number of wires and hoses, and the driveshafts. It is the easiest and fastest way for a customer to do a premium conversion with great simplicity, enjoyment and success.

We'll typically source a low-miles salvage engine of the customer's choice. Popular choices of engines include:

A 4.8L V8 with SM465 Transmission

We can also work with choice, local engine rebuilders if the customer wishes to have a rebuilt or performance-optioned powerplant.

We will build your manual or automatic transmission, installing any required Novak adaptation shafts and components. Our manual transmissions are built like our TurnKey transmissions and our automatic transmissions are built to standard or performance levels, as requested.

Transfer Cases
Most commonly, we use the customer's transfer case. We can arrange shipping to us if you'd like it rebuilt / enhanced or we can supply one from our collection. Any transfer case provided from us will be rebuilt.

Your Jeep
We can build a powertrain for essentially any Jeep, including all Willys & Kaiser Universals, Utility Trucks & Wagons, FSJ's, Jeepsters, CJ's, YJ's, TJ's and XJ's/MJ's.
