Pioneer Mopar LA 1964-2003 239, 273, 318, 340, 360 modified intermediate tower shaft bushing for HIGH RPM use. NOT FOR BIG BLOCK. See other listing for B/RB bushings. SEE YOUTUBE VIDEO INFO at the bottom of this description. These are for CLOCKWISE rotation only. These have been helically machined to funnel the oil to the shaft. This helps reduce the elongation of the bushing bore 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 galley plug like some guys do. This lets the oil be focused on more important areas. The guys have been bugging me for more so instead of grinding them with a needle file I sent to the machine shop.These are not meant to look pretty, they are meant to be functional. When installing there is no specific rotation or 'clocking" position needed. Any questions, just ask. Yes I am an letting out another of my secrets. SEE YOUTUBE VIDEO for demonstration.
