Product Description

The ARP 201-2501 crank pulley bolt kit is built specifically for the BMW B58 engine, using ARP2000 alloy that's heat-treated and precision thread-rolled for significantly greater strength and fatigue resistance than factory hardware. As boost and RPM increase, a properly rated crank pulley bolt becomes critical to keeping the pulley securely fastened under load.

This kit is a smart addition for B58 owners running increased power levels who want reassurance that their crank pulley hardware can keep pace with the rest of their build. Manufactured entirely in-house in the USA, it reflects ARP's long-standing reputation for engineering fasteners that hold up where stock components are most likely to fail.
