LIFTERS CHEV SB HYD ROLLER RETRO-FIT Race

These COMP Cams Chev Small Block 55-86 short travel race hydraulic roller lifters have been engineered from a patent-pending design that specifically performs at higher engine speeds. They are designed to limit the lifter's internal piston as it is pumped up. By limiting that movement, the COMP Cams short travel race hydraulic roller lifters cut down on the loss of power and limit valvetrain failure at higher rpm. The lifters are REM-finished and then black oxide coated for extreme durability, even for those high-revving engines. Fits blocks originally equipped with flat tappet cams where a Hydraulic Roller cam is being retro fitted. .842 diameter.
