Performance

The QST30 delivers more power and more torque in a smaller package than competitive diesels. Known for its flexible calibrations, excellent power density, economical operation and exceptional uptime, the QST30 sets the standard for rugged dependable power.

The QST30 is an excellent choice to replace a number of engines – including some of our own. It has significantly more power, as much as 50% longer life-to-rebuild and better fuel economy than the Cummins V28, even though it is virtually the same size. Repowers are available with air-to-air cooling (for equipment which has to meet emissions standards) or jacket-water aftercooling (for non-emissionized equipment).

If you have an older competitive engine, you’ll find that replacing it with the QST30 gives you up to 25% more power and torque, better fuel economy and longer service intervals, for increased productivity with lower costs. Every Well.

Warranty

– The best warranty in the business, which includes full coverage for unlimited hours during the first year, extending through two years or 2,000 cumulative hours (whichever comes first). The base warranty also includes 3-year/10,000-hour standard protection on major components. Extended warranties are available as well.
