Cummins 4BT 3.9 and 6BT 5.9 Piston Kits
Keep your Cummins 4BT and 6BT engines operating at peak efficiency with piston kits from Diesel Parts Direct. Piston failure occurs from extreme overheating of your engine, carbon build up or fuel injector problems and can even lead to the destruction of your engine block if not caught in time. Before irreversible damage takes place, check out our range of Cummins pistons to suit engines from the 3.9 to the 5.9 Cummins diesels.
With such a wide range available, it can be hard to find the right 5.9 Cummins pistons for your engine. So, if you need advice on the correct fitment for any part, just give us a call on 855.470.3525
Trust Diesel Parts Direct to deliver the right piston kits for Cummins 4BT and 6BT engines.
