Complete Cummins Swap Kit for Square Body 4WD Chevy Trucks
Our 73–87 Chevy Cummins conversion kit is packed with essential components for a smooth Cummins diesel engine swap. It includes a transmission adapter and flexplate to mate a TH400, 700R4, or 4L80E transmission to a 1989-2002 6BT 12 or 24-valve Cummins engine. The bolt-in 2" drop engine crossmember (K-member) ensures proper engine placement and reinforces the chassis to handle the added torque of your square body Cummins swap.
