Governors

Take control of your RPM.

Simms Diesel supplies mechanical and electronic governors for industrial diesel engines, generators, pumps and agricultural equipment.

From simple speed-limit systems to full actuator-style governing units, we stock Woodward-type, Bosch-style, Cummins, Yanmar and universal-fit options — plus rebuild kits, linkages and control levers.

Whether you're replacing a worn-out control or tuning a gen-set for stable performance, we’ve got the gear and the expertise to help you dial it in.
