Antifreeze, Coolants & Performance Coolant Additives
Operating temperature is very important for all engines, whether on the street, off-road, or at the racetrack. When the engine gets too hot, overheating occurs leading to damage such as a blown head gasket or warped parts. To combat and protect from high temps, coolant additives are used. These additives reduce surface tension in water and coolant, providing better heat transfer to the radiator. JEGS offers performance coolant additives and racing coolants from top brands including Redline (gas and diesel antifreeze additive "Super Coolant"), Royal Purple, Evans (waterless coolant and coolant prep fluid), VP Racing, JEGS, and others. View our wide selection of performance coolant additives that will help your street or racing engine run cooler.
