Downsped Systems

Engine downspeeding is lowering engine RPMs at highway cruise to maximize fuel economy and reduce emissions for the entire system. However, the challenge of downsped engines is that they increase torque throughout the drivetrain. Running existing components with additional torque will actually decrease component life over the long haul.

That's why you need to spec the right parts, the first time.
