XLR-8 Series Lifters feature increased diameter oil band for maximum rigidity. Roller bearing pocket is designed for excellent shrouding of the roller bearing, providing strength and stability with smooth rounded edges that minimize lifter bore wear.
XLR-8R Series Lifters feature 4-column design for ultimate strength and rigidity while minimizing mass. Deep roller bearing pocket provides maximum roller bearing shrouding, maximizing rigidity and thrust surface area with smooth rounded edges that minimize lifter bore wear.
