Upper T/A Mount GM

The Upper T/A Mount GM by Allstar Performance is a precision-engineered engine mount specifically designed for GM vehicles that require reliable drivetrain support and isolation. This component is essential for mechanics rebuilding or modifying late-model GM engines, especially when upgrading to higher-horsepower setups or performing engine swaps.

Constructed from high-strength forged steel, the Upper T/A Mount GM is engineered to withstand elevated engine torque and repeated cycles that can destroy stock rubber bushings. Its compact footprint—measuring 5.5 x 0.5 x 9.05 inches—ensures a tight fit in restrictive engine compartments while absorbing vibration and torque reaction without requiring extensive modifications.

Performance enthusiasts and rebuilders will benefit most from this mount when transitioning to solid or modified engine setups, as it maintains proper engine bay clearance and is calibrated to GM's factory bolt patterns for drop-in compatibility.
