NEW EVO-16 STEEL-ON-STEEL LIFTER UPGRADE
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.
XLR-8R Series Needleless Roller Options: All our XLR-8R Series lifters can be upgraded with either our BB1350 bushings for an additional $240, or our EVO-16 “Steel-on-Steel” bushingless option for an additional $420. For endurance use, with up to 1350lbs of max spring pressure, we recommend our BB1350 bushing. For racing, extreme applications, and the ultimate endurance, we recommend our EVO-16 upgrade.
