[FUNCTION] Hydraulic lifters help eliminate the need for internal combustion engines to have mechanical clearance in the engine valve train to prevent the valve from remaining open and damaged as the valve train undergoes a thermal expansion process. [QUALITY ASSURANCE] Tested to ensure leaks and tip oil flow are within specification. Same size as OE parts, rails hold the lifter tight for smooth operation. [PACKAGE INCLUDE] 16 x Hydraulic roller lifters, 4 x lifter guides. ?
