Overview

The GForce GF-GMTM-SP is a set of four transmission mount shims designed for 1963-2001 GM rear-wheel-drive vehicles. These aluminum shims are 1/8" thick with base dimensions of 1-1/4" x 2-3/4" to ensure solid contact between the transmission mount and crossmember. They are useful for tuning drivetrain and driveshaft angles, allowing for adjustments from 1/8" to 1/2". The shims are compatible with both late model GM single centered stud mounts and early model GM dual stud mounts with 1-1/2" between hole centers.
Show original supplier description
The GForce GF-GMTM-SP transmission mount shims are precision-engineered components designed to fine-tune drivetrain and driveshaft angles in 1963-2001 GM rear-wheel-drive vehicles. This set includes four individual aluminum shims, each measuring 1-1/4" x 2-3/4" x 1/8", providing a solid and rigid contact surface between the transmission mount and the crossmember. Unlike standard flat washers, these shims offer superior contact and stability. These shims are engineered to work with two types of GM mount configurations: the late model GM single centered stud mount, and the early model GM dual stud mount that has 1-1/2" between hole centers. The kit allows for adjustments ranging from 1/8" to 1/2", enabling precise alignment of the driveshaft and drivetrain components. It is important to verify your transmission mount's pattern dimensions prior to purchase, as these transmission mount shims are non-refundable. While designed for a broad range of GM RWD applications from 1963-2001, users are advised that "Some Adaptation May Be Required." The product page indicates "THIS WON'T FIT YOUR VEHICLE," suggesting a need for careful verification of compatibility with specific transmission mounts and crossmember setups.
