Chevy GM Powerglide Aluminum Tailshaft Housing with Roller Bearing - TH400 Yoke These Speedmaster air cleaners areThis Speedmaster tailshaft housing are designed to fit the stock GM Powerglide transmissions and accept a TH400 yoke. They are five times stronger and more ridged than stock because they are made from aircraft grade aluminum alloy, thicker walls, and more triangulation than other manufacturers. They also include a roller bearing at the end of the tailshaft which is lubricated by our reworked passage for the yoke and rear bearing assembly.
