4-Speed Main Shaft Bearing Support Spacers

This spacer kit is designed for use with 4-speed main shaft bearing supports—most often needed when running a super nut on your transmission’s main shaft.

Available in your choice of 3/8" stainless steel or 3/8" mild steel, depending on your build needs.

Made in the USA.

A small part that does a big job—no fuss, no flex, just the good stuff.
