COMP Cams 7410-1 Hy-Rev Hydraulic Roller Lifter EVO Sportster Single

The COMP Cams 7410-1 is a Hy-Rev hydraulic roller lifter engineered for Evolution (EVO) Sportster engines. Sold individually, this performance-grade tappet is a direct upgrade over the stock hydraulic roller lifter, delivering improved high-RPM capability and valvetrain stability on the street or strip.

At the heart of the Hy-Rev design is an internal hydraulic check valve that resists pump-up at elevated engine speeds, keeping the valvetrain in control where stock lifters fall short. An oil metering design ensures consistent, uniform oil delivery throughout the entire RPM range for dependable lubrication under all operating conditions.

Key Features:

• Hy-Rev anti-pump-up design with internal hydraulic check valve for extended high-RPM operation
• Rollers and axles manufactured from high-carbon/chromium bearing-quality steel, through-hardened for superior wear resistance and load-carrying capability
• Carbo-nitrided pushrod seat for increased surface hardness and longevity
• Precision oil metering design provides uniform lubrication across the full RPM range
• Produced on CNC-controlled machinery to tolerances of 0.003 in. for a precise, consistent fit
• Sold as a single (individual) lifter — order the quantity needed
• Made in the U.S.A.
• Requires adjustable pushrods
