The J.W. Performance Ultra-Bell is one of several examples of our leading technology.
Designed not only to be a SFI certified flexplate shield, the Ultra-Bell allows special
motor and transmission combinations to be easily mated together. This one piece cast aluminum
bellhousing, which is 600 times stronger than a stock bellhousing, can withstand even
the most severe tire shake and it fits under stock floor boards. Installation of the Ultra-Bell is
easily done by removing the stock bellhousing and bolting the Ultra-Bell to the front pump
with the high-grade bolts supplied. See chart below for correct Ultra-Bell.
