Hustler Short Travel Hydraulic Roller Lifters for GM 603/604 Crate Engines - Single
COMP Cams® Hustler™ Lifters for GM 603 & 604 Crate Engines look stock but offer superior performance in race applications with tight rules packages
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.
