Looking for a complete powertrain package for your 2WD application? You’ve found it! You will receive a brand new Cummins R2.8 Crate engine, Tremec 2-wheel drive TR-4050 5 speed manual transmission, and a Quick Draw Brand  adapter kit to mate the Cummins R2.8  to the Tremec TR-4050.  Our complete package is priced much cheaper than piecing the individual components together, saving you significant money and guesswork! Note that this is not a complete installation kit but includes the most critical parts to get your project started.

Our Cummins R2.8 and Tremec TR-4050 Package Includes{Cummins part number 5467046}:

  • Cummins R2.8 crate engine assembly (Cummins part number 5467046)
  • Tremec 2-wheel drive TR-4050 with shifter stub
  • Quick Draw Brand bell housing adapter kit using an external slave cylinder
  • Complete clutch kit
  • External slave cylinder
  • HD clutch fork, pivot ball, and throw out bearing
  • Flywheel with pilot bearing installed

Note the unique design of our adaper kit utilizes commonly available off-the-shelf wear items that can be purchased at any auto parts store, so items like the clutch kit and external slave cylinder are not proprietary and can be purchased elsewhere. This maximizes ease of maintenance over the long term and minimizes down time, not to mention headaches down the road.


The Cummins R2.8 is allowed in Tier 1 compliant vehicles and older with cut-off dates around 1999 for light duty trucks and 1993 for light duty cars.  If you are unsure whether or not the recipient of your powertrain conversion qualifies, please contact us prior to ordering. Note that all purchasers will be required to provide vin number for verification prior to shipment of parts for proof of compliance.
