SBC R/Z Roller Lifters EZ Max

The ISKY Cams SBC R/Z Roller Lifters EZ Max are specifically designed for small-block Chevrolet engines utilizing roller cam profiles, making them ideal for performance builders and street enthusiasts who demand reliability and efficiency. These lifters represent an advanced evolution of lifter technology, engineered to withstand high-RPM operation while minimizing friction losses in the valvetrain.

The EZ Max design features precision-machined bearing surfaces and optimized roller geometry, which significantly reduces lifter-to-bore friction while maintaining the necessary tolerances for accurate valve timing. This roller design converts sliding friction into rolling contact, extending component life and allowing for full lift profile transmission without distortion.

These lifters are manufactured from high-strength ductile iron and are precision-ground to ensure consistent oil film strength, making them a superior choice over budget alternatives. They are compatible with various small-block Chevy configurations, including 283, 327, 350, and 400 cubic inches, providing a solid upgrade for those looking to enhance their engine's performance.
