SPHT2148 - SPEED PRO SPEEDPRO OEM LS1 HYD ROLLER LIFTERS

Speed-Pro hydraulic roller lifter provides significant friction reduction while greatly increasing horsepower and fuel economy at the same time. Valves open more quickly from a fully closed to a fully opened position with a hydraulic roller lifter when compared to a conventional flat lifter. This then provides for enhanced performance, quieter engine operation, more horsepower and still allows for proper vacuum and idling capabilities.
