SFI-Rated Bellhousings
SFI-30.1 certified as flywheel shields, JW Performance Ultra-Bell Bellhousings feature patented T6 aluminum castings that endure twisting and tire shake. These stronger-than-stock housings bolt to the front pump and fit underneath stock floors. Models mating Ford or Chrysler V8 to Powerglide eliminate adapter plates (starter mounts to Ultra-Bell).
Note: Ultrabell does require removal of OEM housing which is a simple task that can be performed with ordinary hand tools.
