Cummins 4BT 3.9 and 6BT 5.9 Turbochargers

Supercharge Cummins 4BT and 6BT engines with turbos from Diesel Parts Direct. Fundamental to the operation of diesel engines, B Series turbos reduce fuel consumption and keep 3.9 and 5.9 diesels performing like they just rolled off the factory line. Over time, wear and tear can deteriorate the seals and bearings, so when you need a replacement 6BT or 4BT Cummins turbo, you’ve come to the right place.

Choose from a range of aftermarket turbos for 5.9 Cummins to remanufactured turbochargers for the 4BT, and as a bonus, we offer free shipping for selected items, with many included in our In-Stock Guarantee.

Boost your Cummins B Series engine’s performance with turbochargers from Diesel Parts Direct.
