Description

Our 73-87 GM Truck K Series Cummins Kit is comprised of many of the items needed for your Cummins diesel engine conversion. It includes a transmission adapter and flexplate to mate a TH400, 700R4, or 4L80E transmission to a 6BT Cummins engine.  Our Cummins bolt-in 2" drop engine crossmember (or K Member) allows for proper engine placement and provides chassis strength to accommodate the added torque of the Cummins!

  • Fits Truck Model Years: 73-87.
  • Fits Engine Years: 89-02.
  • Fits Transmissions: Chevrolet TH400, 700R4, 4L80E.
  • This kit is comprised of some of our most popular items for your 73-87 Chevy K Series Cummins conversion.
  • The Kit includes:
    • GF-C-S - Adapter and Flexplate-  The 5.9 Cummins to Chevy Adapter Plate and Flexplate Kit accommodates 2002 and earlier Cummins 6BT engines bolting to a Chevy automatic transmission such as a TH400, 700R4, 4L80E, or similar transmission.
    • GF-GMDC - Cummins 6BT to Chevy Drop Crossmember-  This 2" drop crossmember allows proper engine placement and often eliminates the need for a lift kit when installing a Cummins 6BT into a 73-87 Chevy 4WD truck.
    • GF-C-MM - Motor Mount- When installing a Cummins 6BT into your 1973-1987 Chevy pickup, this conversion motor mount allows for proper placement of the engine directly to the OEM frame mount isolators. When used in conjunction with a G Force GF-GMDC Drop Crossmember on 4WD models, you can retain OEM drivetrain height. Without our GF-GMDC Drop Crossmember a vehicle body lift is required.
    • GF-BoltKitAdapter - Adapter Bolt Kit,  Premium grade bellhousing adapter bolt kits to make mounting the adapter plate to engine as simple as possible. Set of 9 bolts.
    • GF-BoltKitFP - Flexplate Bolt Kit, -Flexplate bolts for mounting your Cummins 6BT to a GM Bellhousing. 12mm x 1.25. 25mm underhead length. Set of 8 bolts
    • GF-BoltKitStarter - Starter Bolt Kit - Steel, zinc plated bolts constructed to strict engineering quality standards and serve as direct replacement bolts for replacing the Cummins 6BT starter. Set of 4 bolts with 3 washers
