Product Details

Holeshot™ Torque Converter (70421) by B&M®. Material: Steel. The B&M HoleShot converters are an excellent choice for improving acceleration and increasing drivetrain strength in virtually any street machine. An added benefit of a Holeshot high stall converter is when a higher duration camshaft is used, the engine idle is greatly improved when stopped in gear. These high quality balanced converters come standard with full furnace brazed impeller and turbine, heavy duty needle type thrust bearings, and new turbine hubs.

The reason for considering B&M torque converters boils down to performance. Higher stall speed is the key. A higher stall converter allows the vehicle to accelerate better from a dead stop and may provide tire-smoking performance. B&M offers a wide range of performance torque converters to fit almost everybody's needs. From the Tork Master, to the Nitrous Holeshot for street applications to the Quick 60 Race converters for racing, B&M has the right converter for your vehicle. All B&M converters are precision engineered, spin balanced and pressure tested.
