Lakewood's Safety Bellhousings are made for just one purpose…to minimize the destructive effects of a clutch/flywheel explosion. The stock cast aluminum bellhousing is adequate for OEM applications, but mounted behind a high RPM, high horsepower engine, a cast aluminum bellhousing would disintegrate from a clutch/flywheel explosion. When using a stock aluminum bellhousing, the only protection you have for your legs and feet is the thin sheet-metal floor boards. There is also the possibility of an innocent bystander being injured from debris being thrown form under the car. For your own safety and the safety of others, always use a proven Lakewood Safety Bellhousing in any high performance application.
