Crane has also been hard at work in the area of lifter development. This is the companyy's Ultra-Pro Series 8620 Alloy Roller Lifter. We could give you the technical jargon, but the bottom line is that these mechanical-roller lifters are lighter (for increased rpm potential and reduced stress on the valvetrain), stronger (38 percent more than the competition, they say), and reliable. The lifters' "four-column" design was developed though FEA (Finite Element Analysis) to create this melding of light weight and strength.
