Energy Suspension Hyper-Flex Polyurethane Transmission Mount, Red - Select GM 1984-2021 (3.1171R)

Fits select 1984-2021 Chevrolet and GMC trucks, vans, and SUVs including Silverado, Sierra, S10, Suburban, Yukon, and Escalade. This performance transmission mount is engineered to replace soft factory rubber mounts that are prone to failure under high-torque conditions.

Constructed from Energy Suspension's proprietary Hyper-Flex polyurethane, this mount provides the ideal balance of firmness and vibration damping. Unlike OEM rubber which degrades over time when exposed to road salt, oil, and under-vehicle chemicals, this polyurethane component remains resilient. It effectively maintains proper driveshaft alignment to prevent drivetrain wear and power loss. The unique safety interlock design ensures the mount remains secure even under the most demanding racing or heavy-duty towing applications.
