Heavy Duty & Marine

A Global Leader in Dependable Parts

Diesel engines have a reputation of strength, durability and efficiency that is required of every system of the powerplant. Our components are up to any task. GT Technologies diesel valvetrain components and systems have been thoroughly tested in the lab and in the field with proven results.

Our durable tappets are used in applications from injection pumps delivering fuel at pressures vital to efficient combustion to opening the valves that make the engine breathe. These high loads often require the use of journal bearings and cryogenic assembly. GT Technologies rocker arms are engineered with unique features to withstand the high combustion pressures only found in the diesel cycle.

Don’t allow your high-performance marine cylinder heads to have parts that aren’t suitable for the job at hand. Our quality valvetrain assemblies and various components prevent catastrophic failures.
