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.

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

Lakewood safety bellhousings are designed for maximum performance and durability. They are cut on CNC 5 axis laser cutters rather than plasma cutters to improve finish quality, reduce heat damage and warpage from the plasma cutter, improve speed of manufacture, and make them all exactly the same. All bellhousings feature a scalloped plate on the bottom of the transmission surface made from G70 grade steel (70,000) psi which will help eliminate stripping the transmission bolts. The engine plates are made of H60 grade material and the bells are roto-brated after welding to relive any stresses created from the hydro forming, annealing, or welding process prior to machining and painting. The roto-brating process also closes the metal on the outer surface making them stronger. Ever wonder how the SFI tests bellhousings like these Lakewood safety bellhousings? First, they bolt the bellhousing to a machine with a cast iron flywheel and saw inside it. Then they spin the flywheel, causing the saw to cut through it until it explodes. If the bellhousing can contain the explosion, the bellhousing is approved. These safety bellhousings are a safeguard to minimize the destructive effects of such an explosion. Don't take unnecessary chances with your safety and the safety of innocent bystanders--Lakewood not only provides top-notch products, they also provide peace of mind.
