105 HP Cummins #4BT, remanufactured extended long block engine

Remanufactured Cummins 4BT in Stock – 105 HP Complete Diesel Engine

Our long block and extended long block assemblies are considered 'component builds'. A component build is an engine assembly built back to popular configurations using roughly 90% OEM New Parts, 10% Aftermarket when available. Our 4BT 105 HP units are great for an industrial application; either a re-power or for replacing an existing older 4BT (3.9 L) unit. We traditionally build these with more robust inline fuel systems but do offer lower horsepower/torque setups with a VE rotary pump upon request.
