Racers know that a cooler running engine is a better performing engine. Reducing the temperature at which an engine runs will make more power through better thermal and volumetric efficiency. SLP offers this new thermostat that replaces the factory 195° unit, allowing coolant to circulate at lower engine temperatures, keeping the engine cooler.  Fits the following applications:

  • 1997-2003 4.8L/5.3L/6.0L Silverado/Sierra/SUV (GM/GMC Truck/SUV 800 Series)
  • LS1 1997-03 Corvette
  • LS1 1998-02 Camaro/Firebird

Not legal for use on pollution controlled vehicles.

NOTE: Add the SLP Fan Control Switch (Part #63011) for complete engine temperature control!
