The Visconti Tuning High Torque Crank Pulley for B58 and S58 engines is designed to prevent the pulley from separating on high horsepower applications.

Factory B58 and S58 crank pulleys use a pressed two-piece design which can begin to slip or separate as torque levels increase. This upgraded crank pulley improves clamping force and reliability for engines running higher boost levels, upgraded turbos, or aggressive tuning.

Designed for high performance builds, this pulley helps prevent crank pulley movement while maintaining proper alignment and durability under extreme load conditions.

Engineered specifically for BMW B58 and S58 platforms, this upgrade provides a simple and reliable solution for engines operating beyond factory power levels.
