SFI-Approved, No Transmission Shield Required

This one-piece aluminum casting replaces the stock GM case and allows versatility when an adapter-style Ultra-Bell housing is used. Ultra-Case has an adjustable transbrake release; CNC-machined oil passages to increase oil flow and improve performance; and more material in critical areas to reduce flex around the shift lever, which lowers the chance of the case cracking. Made in the USA!
