Cummins 4bt Jeep Conversions

Over the past four years BB Diesel Performance has concentrated all our efforts on Diesel Trucks. We recently decided to begin offering Cummins 4BT Jeep Conversions. The conversions are pretty straight forward installing a 3.9L Cummins 4-cyl into your Jeep, small pickup, SUV, or you name it. The video below was made by Bruiser Conversions of Florida.

They have been doing the Cummins 4bts swaps since 1995 and really have this perfected. We are very familiar and already understand the larger cousin, 6BT Cummins used in the Dodge RAM 2500 Cummins Diesel. Some cummins 6bt parts are actually interchangeable with the cummins 4bt. We will initially be building with NV4500 5-speed manual transmissions. There are many possible combinations of suspensions systems, transmissions, etc. Shipments of cummins 4bt’s will be arriving soon. Jeep conversions are the most popular, but we have seen the 4bt installed in most anything you can imagine.

Cummins 4bt Jeep Conversions are growing in popularity as fuel prices climb to historic highs. Jeep swaps can reach 28-32 mpg hwy with a stock motors and correct gearing.
