Stock bellhousings can't withstand the punishment of today's top derby's.  You don't want a broken transmission bellhousing to keep you from winning the feature.  Using the latest technology, J.W. Performance has developed the Ultra Bell bellhousings. They are designed to be certified flexplate shields and allow for special motor and transmission combinations to be easily mated together. J.W. Performance Ultra Bell bellhousings are manufactured from one-piece cast aluminum, making them 600 times stronger than stock bellhousings. They are capable of taking a beating and still deliver power to the rear end.  Ultra Bell's are designed to fit under most stock floorboards, and are made in the USA.

Stock bellhousing must be cut off of transmission. This bolts directly to front pump. Bolts included. Will work with OEM 12 in. torque converters and smaller.

Here's the pictures of the new design!
The design of the back is flat now instead of curved and will perform better when pushed up against the firewall.
