These high-performance thermostats are designed to resist large variations in coolant pressures that occur at high-rpm where coolant temperature and pressure fight for control of the thermostat and keeping it from opening at its designated temperature. The balanced HP thermostat features all brass and copper construction and opens at the right temperature regardless of engine rpm.
