    Bellhousing Material
    Manufacturer's Part Number:

    10-Pound Housings about 5-Times Stronger than Stock Bellhousings

    SFI-30.1 certified as flywheel shields, Ultra-Bells feature patented T6 aluminum castings that endure twisting & tire shake. They bolt to front pump and fit under 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 bellhousing which is a simple task that can be performed with ordinary hand tools.

    92451 is rated 5.0 out of 5 by 8.

    JW 's website has 92452 specifically for the TH350, your listing provides for both. Has JW made the 92451 ubiquitous to both the 400/350 or do I need the 92452 for the TH350?

    Asked by: Badbowtie
    The 92452 is no longer available, replaced by the 92451 that will fit both TH350 & TH400 transmissions.
