Product Details

The USA Standard Gear ZM465WT304-81 is a precision-engineered 1st and 2nd gear synchronizer hub designed specifically for GM Muncie SM465 (also known as CH465) 4-speed manual transmissions. This critical transmission component serves as the mounting point for the synchro assembly that enables smooth shifting between first and second gears.

Key Features:

  • Direct replacement for GM OEM part number 3946776
  • Professional quality construction meeting ISO9001 certification standards
  • Industry standard part number WT304-81 for cross-reference compatibility
  • Precision-manufactured to ensure proper synchro operation and gear engagement
  • Essential component for transmission rebuilds and repairs

This synchro hub is compatible with SM465 transmissions found in Chevrolet and GMC C and K series pickups, Blazers, Jimmys, and Suburbans from 1968 to 1991. The SM465 can be identified by its cast iron case with either a cast iron top cover (1968-1987) or aluminum top cover (1988-1991). USA Standard Gear manufactures a complete line of high-quality transmission parts, offering reliable replacement components for manual transmission, differential, and drivetrain repair needs.
