Heavy Duty OEM

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

GT Technologies 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 profiles to withstand the high combustion pressures only found in the diesel cycle.
