Energy Suspension Hyper-Flex Polyurethane Motor Mount Insert Set

Energy Suspension's Hyper-Flex™ Polyurethane Motor Mount Insert Sets are engineered to significantly reduce engine movement and improve power transfer in performance vehicles. These precision-crafted inserts fill the voids in factory motor mounts, creating a more solid engine-to-chassis connection — without the harshness and NVH penalties associated with fully solid mounts.

Built from Energy Suspension's proprietary Hyper-Flex™ performance polyurethane, each insert is formulated to outperform OEM rubber in virtually every measurable way. Hyper-Flex™ polyurethane resists compression set over time, meaning the inserts maintain their shape and effectiveness long after standard rubber mounts have softened, cracked, or deteriorated.

Key Features:

• Made from Hyper-Flex™ polyurethane for exceptional durability, resilience, and long service life
• Dramatically reduces wheel hop and traction loss during aggressive acceleration and hard launches
• Eliminates excessive engine movement that can stress and damage nearby hoses, wiring, and components
• Restores performance characteristics to worn or softened factory rubber mounts without requiring full mount replacement
• Highly resistant to automotive fluids including engine oil, coolant, power steering fluid, and road contaminants
• Delivers a performance-tuned balance between vibration isolation and rigid power transfer
• Suitable for street, autocross, road racing, and drag racing applications
• Designed to drop into existing factory mount housings for a precise, rattle-free installation with no modification required

Unlike complete mount replacements, motor mount inserts are a cost-effective and straightforward upgrade that targets the root cause of engine movement — the soft, void-filled rubber of the OEM mount. By filling those voids with durable polyurethane, Energy Suspension inserts allow more efficient power delivery to the driven wheels while maintaining acceptable NVH levels for daily street use.

Energy Suspension has been a trusted name in performance polyurethane suspension and drivetrain components since 1952. Each insert set in this product line is designed to work within existing factory mount housings, making them an ideal first-step performance upgrade for enthusiasts who want real-world results without a full mount replacement.
