Energy Suspension Hyper-Flex Performance Polyurethane Motor Mounts

Energy Suspension's Hyper-Flex® Performance Polyurethane Motor Mounts are a proven upgrade for drivers who demand more from their engine mounting system. Engineered as a true performance solution for cars, trucks, hot rods, and competition vehicles, this product line bridges the gap between the compliance of OEM rubber and the rigidity of solid metal mounts — delivering durability and performance that excels in both street and track environments.

Stock rubber motor mounts are designed primarily to absorb noise and vibration, but the torque generated during acceleration causes rubber to flex, fatigue, and eventually deteriorate. The result is sluggish throttle response, sloppy drivetrain feel, and costly repeat replacements. Hyper-Flex® polyurethane occupies the ideal middle ground — significantly firmer and more stable than rubber, yet compliant enough for comfortable daily street use — without the harsh vibration transmitted by solid metal racing mounts.

Key Features:

• Hyper-Flex® Performance Polyurethane Construction — A higher-durometer material formulated to outlast OEM rubber mounts and resist breakdown under sustained mechanical and thermal stress
• Torque-Resistant Safety Interlock Design — Where required, an integrated safety interlock provides strength comparable to solid metal mounts without transmitting excessive NVH (noise, vibration, harshness) to the cabin
• Chemical and Contaminant Resistance — Resists motor oils, coolants, road salt, grime, and other under-vehicle fluids that accelerate rubber wear and degradation
• Improved Throttle Response and Drivetrain Efficiency — Reduces unwanted engine movement to deliver more immediate power transfer and sharper acceleration feel
• Reduces Wheel Hop and Traction Loss — Keeps the engine stable and properly aligned with the drivetrain, especially under high-torque and high-performance conditions
• Prevents Damage to Other Components — Eliminates the excessive engine movement that can stress surrounding drivetrain and chassis components over time
• Drop-In Replacement Design — Engineered to replace worn OEM rubber mounts without requiring modifications to the vehicle
• In-House Manufacturing — All design, engineering, and production are handled internally for the strictest possible quality control and consistent part accuracy
