JEGS Powerglide Output Shaft Support is CNC machined from billet 6061-T6 Aluminum. This special high strength lightweight support is built for racing and eliminates the provisions for the governor. This support replaces the stock part and comes with a roller bearing inside to lower friction and lasts longer than stock. Suitable for use with long or short tail-shaft housings (does not replace tailshaft housing in drag racing applications). Ideal for bracket ET and professional drag racing.
