Eaton Detroit Truetrac differentials use a patented design of parallel-axis planetary helix gears to provide a quiet, automatic splitting of torque. They perform like a limited-slip differential under normal driving conditions, automatically transferring torque to the wheel with better traction when ground conditions warrant. These replacement units are available for dozens of axle applications.

A higher-than-stock stall speed as delivered by these B&M Holeshot converters will provide several advantages and benefits to vehicles with modified engines. Many modifications, particularly big cams, tend to reduce low-end power and torque. These high-stall converters allow the engine to launch the car at higher rpm, where more torque is available. They're a very good choice for the typical street machine that is looking for better launch capability and more strength.

Nitrous engines produce some serious horsepower and require a serious torque converter to handle it. B&M nitrous Holeshot torque converters can handle up to 650 hp and are built with the same features as the other B&M Holeshots, with the addition of anti-balloon plates that allow these converters to stand up to the instant horsepower that nitrous delivers. Converters with higher-than-stock stall speed let your ride accelerate better from a dead stop and allow the vehicle to idle better when a big cam is used. Fully furnace brazed, heavy-duty, needle-bearing thrust packages and new turbine hubs are the key features of these converters, along with the anti-balloon plates. These are serious converters for serious street performance cars.
