Description
Part #: ST123-16
Hustler Lifters feature reduced internal piston travel for increased stiffness and greater valve lift when compared to stock
lifters in Sealed GM 603 and 604 crate and 1987-1998 GM small block engines. The short travel design also increases responsiveness, allowing for quicker recovery from any valve float or bad harmonics in the valve train.
COMP Cams Hustler Lifters for GM 603 and 604 Crate Engines look stock but offer superior performance in Race Applications with tight rules packages.
