Performance Valvetrain

Your valvetrain controls the operation of the valves. Your factory valvetrain isn’t meant to function or handle the power from your performance engine. High valve spring pressure helps prevent valve float at higher RPMS. A performance valvetrain is made from stronger components to overcome the valve spring pressure to open larger valves. Sport Compact Warehouse is your premier source for Performance Valvetrains. If you have any questions regarding performance valvetrains, reach out to one of our experienced representatives and we will help you make a more informative decision.
