Description: NEW Pioneer Modified intermediate tower shaft bushing for Mopar B,RB 383 400 426 440 motors only. SEE YOUTUBE VIDEO INFO at bottom of this description. These have been helically machined to funnel the oil to the oil pump shaft reducing oblong wear, expecially at HIGHER RPM's and prevents premature gear failure. The oil slots in bore are large enough for oil to easily enter and also acts as a reservoir. No need to drill a hole in the lifter oil galley plug like some guys do. Let that oil be focused on more important areas. NOT FOR SMALL BLOCKS (see other listing for 340's). These are for COUNTERCLOCKWISE rotation only. I used to grind these with a needle file. Made a bunch because the guys keep bothering me, so I had them machined. There is no specific rotation or "clocking" needed when installing. Another trick I am sharing. Any questions, just ask. They are meant to be functional, not pretty. If you run a reverse rotation marine engine, you will need to order the small block bushing for correct rotation.SEE YOUTUBE VIDEO WITH DEMONSTRATION.
