Cummins

Cummins engines are available in a wide range of medium- and heavy-duty trucks from brands like Mack, Hino, Isuzu, Autocar, and select Volvo models. TEC Equipment offers Cummins-powered trucks across urban delivery, vocational, and long-haul Class 8 applications.

Cummins engines offer horsepower ranging from 200 to 605 hp and torque ratings up to 2,050 lb-ft, depending on the model and configuration. The X15 and L9 are widely used in regional and long-haul fleets for their balance of performance and fuel economy.

The X15 is Cummins’ evolution of the ISX15, designed with improved thermal efficiency, reduced emissions, and enhanced uptime. While both offer similar displacement (15L), the X15 provides better integration with digital diagnostics, making it the preferred option for modern fleets While keeping up with the evolving emissions standards.

For commercial fleets, 24-valve Cummins engines (like the ISB and later B6.7) offer more precise fuel injection, improved power output, and better emissions control compared to older 12-valve models. While 12-valve engines are simpler and easier to work on, 24-valve systems are more efficient and compliant with current regulations.

Top-performing Cummins models include the X15 for heavy-duty long-haul, the L9 for regional delivery and vocational work, and the B6.7 for medium-duty platforms. Each engine is optimized for reliability, fuel economy, and low maintenance costs. TEC Equipment supports sales and certified service for all Cummins platforms.
