Description

The B&M Holeshot 2000 Torque Converter enhances vehicle launch by allowing the engine to reach higher RPMs before moving. Ideal for street machines and rods with modified engines that have reduced low-end power/torque. It provides a higher stall speed, enabling the engine to launch at a higher RPM where more torque is available for better acceleration. Constructed from premium-grade materials with a balanced, furnace-brazed impeller and turbine for durability under high torque/horsepower.
