Description_MKT A higher than stock stall speed as delivered by a B&M Converter will provide several advantages. The high stall converter allows the engine to launch the car at a higher RPM where more torque is available and increased strength.
Description_MKT This B&M Tork Master 2400 fits 1980-92 Ford AOD transmissions with a 1.375-inch crank pilot and has a 11.4-inch bolt circle. Dont let the exceptional value fool you into thinking Tork Master Converters are not packed with lots of quality features, making 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. Upgrades like a new precision alloy steel pump drive tube, needle thrust bearing when factory equipped, new thrust washer between turbine and cover when required, and pressure tested and fully balanced by expertly trained technicians. Notes: Higher stall converters can generate more heat, so we highly recommend adding a transmission cooler. Not recommended for big block, supercharged, plate-type nitrous oxide or trans-brake applications.
