B & M – B & M Torque Converter, Nitrous Holeshot 3600, 20482 (Part No.20482)

B & M Torque Converter, Nitrous Holeshot 3600, 20482

from

$799.99
B&M Nitrous HoleShot 3600 stall for 1965-91 TH400, 425 and 1968-81 TH350, 375 (Not TH350C) transmissions is an excellent choice for vehicles with 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 where more torque is readily available, resulting in quicker acceleration. Nitrous Holeshot converters feature furnace brazed impeller and turbine, new precision steel alloy pump drive tube, new heavy duty needle bearings between the stator and impeller (not a thrust washer) and needle bearings between the stator and turbine. Other features include dual pattern 10.75 and 11.50-inch bolt circle, a new turbine hub, new springs and rollers in the stator and anti-balloon plates. The anti-balloon plates will allow these converters to stand up to the instant horsepower that a nitrous plate system delivers. Stall speed listings are based on engines producing 230lb. ft. of torque at 2,500 rpm. More torque at 2,500 rpm will give you more stall speed, less torque at 2,500 rpm will give you less stall speed than the stall speed ratings indicated. These are serious converters for serious performance street cars. To prevent contamination left from worn parts being circulated in your new components causing premature wear, we strongly recommend protecting your investment by adding a B&M transmission cooler with all new transmission installations. Listed converters are NOT to be used in trans-brake applications. Not for use in trans-brake applications.

B & M – B & M Tork Master 3000, 20402 (Part No.20402)

B & M Tork Master 3000, 20402

from

$584.99
The Tork Master 3000 fits 1965-91 GM TH400, 425, 375 and 1968-81 GM TH350, 375B (not 350C) transmissions. Don’t 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. The product images shown are for illustration purposes only and may not be an exact representation of the product. 10.75-inch bolt circle

The best value priced street converters available, Tork Master converters come with a new precision pump drive tube and all are pressure tested and fully balanced. The Tork Master torque converter is not recommended for big block or supercharged applications. New alloy steel pump drive tube. Needle thrust bearing when factory equipped.
