Sonnax bushing GM-B-8 provides rebuilders with a replacement for damaged or worn bushings in GM 6T40/6T45 converters that utilize an impeller hub bushing. Made from aluminum bi-metal alloy with steel backing for high load capacity, this clinched-seam impeller hub bushing has two diagonal grooves inside the bushing to enhance oil flow.
Not for use with Sonnax GM-90-75G.
