COMP Cams Hustler Short Travel Hydraulic Roller Lifters GM 603/604 - Set of 16

With their reduced internal piston travel, these COMP Cams Hustler lifters offer a stiffer valvetrain compared to stock options. This design choice matters because it allows for greater valve lift, which can make a noticeable difference in how your engine performs, especially in sealed GM 603 and 604 crate engines, as well as 1987-1998 GM small blocks. They are built to look like stock components but provide a performance edge for racing applications with strict rules.

The short travel design isn't just about lift; it also makes the valvetrain more responsive. This means it can recover quicker if the valves experience float or if there are any harmonic issues. For anyone working on a GM 603 or 604 crate engine, these lifters are a solid option for improving the performance and reliability of your engine's top end.
