Boss Hog Street Bandit Torque Converters

Torque converters are considered one of the most mysterious mechanical components in today's vehicles. They function like a clutch, and keep the engine running even when the vehicle comes to a halt. By designing the stall speed to match both the engine and desired stall speed, ACC Performance converters help low-end idle speeds, improve performance, and acceleration. ACC Performance Products has emerged as an out-right leader in torque converters and here's why: * Boss Hogs are welded, not furnace-brazed; furnace brazing is not the best way to adhere torque converter components, it will erode and ruin the stators and all rotating parts * Industrial Torrington bearings handle more torque than smaller, uncased needle bearings * Aircraft aluminum washers instead of fiber washers put more horsepower and torque directly to the ground * ACC converters are hand-built and tested to ensure that you get the best converter money can buy * With returns below one percent, you are assured of the highest quality parts available * Street Bandit converters are designed to handle as much as 650 hp * Custom-engineered turbine hubs maintain the highest quality, strength, and durability * Stators are built with high-flow vents and channels for greater cooling to handle greater power and higher temperatures * Engineered with a single bolt pattern that makes ACC converters surprisingly light to free up your motor and allow it to gain rpm quicker Notes: * Boss Hog Street Bandit torque converters are not designed to handle the extreme shock and abuse of nitrous oxide or trans-brakes * It is imperative that a transmission cooler be added with any torque converter that is rated over stock stall speed
