American Powertrain is introducing a Square Body Chevy/GMC 4×4 kit for the Tremec TR-4050 five-speed, four wheel drive manual transmission designed to fit 1973 to 1987 pickups and SUVs, which the company notes includes Chevy Suburbans, Jimmys and Blazers.
The kit includes: an aluminum CNC machined bell housing, Hydramax hydraulic clutch and components, flywheel and bolts, transmission mount, pilot bearing, harness, and shifter, shifter knob, transfer case adapter for 10-spline NP205 and all necessary hardware. Options are available for upgrades including shifter, clutch and more. The company says that this kit takes advantage of the low gearing for 4×4 applications with larger tires and high torque loads. The 4050 can handle up to 600 ft./lbs. of torque.
