Description

The G Force Performance Products GF-GMTM-SB2 is a 2-inch transmission mount spacer-block designed for 1963-2001 GM Rear-Wheel Drive applications. It is compatible with all GM two-bolt style transmission mounts.

This spacer addresses vertical misalignment issues that can occur between a transmission mount and crossmember during transmission swaps, due to variations in transmissions or motor mounts. It bolts to the transmission mount, ensuring solid contact with the crossmember to establish proper drivetrain geometry.
