Strength and rigidity is the key to any foundation, which is why J.W. Performance developed the Ultra-Case. Most engine builders would not build a high horsepower race engine in a stock block, so why build a race Powerglide with a stock case. The all aluminum Ultra-Case is the strongest and most rigid foundation available to build your Powerglide with. Designed to be used with the Ultra-Bell, this case is loaded with benefits such as: improved oil passages, adjustable transbrake release, increased material thickness in critical areas which results in elimination of case breakage, and it fits under stock floors. The Ultra-case is SFI certified and can be outfitted with our SFI certified deep pan to eliminate the need for any external straps or shields.
