With a cable-operated mechanism, a universal floor-mount console, NHRA/IHRA-approved reverse lockout, a neutral safety switch, and a polished aluminum T-handle, the StarShifters are at home on the street or the track.

B&M Holeshot Torque Converters

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.

Hays Heavy-Duty Flexplates

Hays heavy-duty flexplates for high performance and competition engines are constructed from a thicker-than-stock steel plate. This enables them to withstand the stress of high-stall torque converters and high-rpm engines. While factory stock plates tend to crack around the crankshaft hub when punished under high-torque and rpm conditions, the thicker Hays flexplates can handle the force. These heavy-duty flexplates are supplied with a ring gear that is securely welded in place. All Hays heavy-duty flexplates are zinc-dichromate plated to resist corrosion and SFI-certified under specification 29.1.

Lakewood Safety Bellhousings

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.
