LUNATI/HOLLEY 72431-16 Features:
High RPM Hydraulic Roller Lifters are designed for extreme street and all out racing applications. At over 6500 RPM, the hydraulic internals of a standard roller lifter are susceptible to valve float, which robs the engine of horsepower and can cause serious damage to the valvetrain. Offering increased durability and reliability, these lifters are specifically developed to handle applications producing over that volatile 6500 RPM point.- Lunati High RPM Hydraulic Roller Lifters are designed for extreme street and all out racing applications. These lifters provide increased durability and reliability, and are specifically developed to handle applications producing over 6500 RPM.
Note: All weights are for pairs including link bar unless otherwise specified.
