BAM Roller Lifters Technical Information
BAM Roller Lifters was founded in 2009 with the aim of providing the highest quality lifters directly to the engine builder. Each lifter is 100% Made In the USA and is meticulously assembled by hand with the highest degree of accuracy. In 2023 BAM teamed up with SRI Performance to provide a more efficient distribution process and a better end user experience.
BAM roller lifters feature a 4-column design for ultimate strength and rigidity while minimizing mass. Deep roller bearing pocket provides maximum roller bearing skirting, maximizing rigidity and thrust surface area with smooth rounded edges that minimize lifter bore wear.
