B&M HoleShot Torque Converters are for serious-minded performance enthusiasts and offer additional strength and durability features not found in our Tork Master or Traveler series of converters. The Holeshot converter is an excellent choice for vehicles with some performance engine modifications, particularly big cams that tend to reduce low-end power and torque. The higher stall speed of this converter will launch the car in a higher rpm range, resulting in quicker acceleration.

B&M Tork Master Torque Converters are packed with lots of quality features which make them the best value-priced street performance converters money can buy. These converters perform best when paired with stock to modified engines up to 350hp/350 ft lbs of torque, and lighter weight applications, like street rods. The Tork Master will provide noticeably quicker launches and harder acceleration while maintaining normal daily driving qualities.

B&M Traveler torque converters are an excellent choice for stock vehicles, vehicles with light performance modifications, tow vehicles and RV's. The additional stall of the Traveler converter makes acceleration much crisper, easier for towing and just fun to drive. B&M Traveler converters are fully balanced and pressure tested by expert technicians and are manufactured to B&M's exacting tolerances for long service life.
