Cusco 509 911 SET Engine Motor Mount Set CD9A CE9A Evo 1-3

The Cusco 509 911 SET is a performance engine and transmission mount set engineered to significantly reduce drivetrain movement, minimize engine pitching, and improve throttle response for high-revving, high-output applications. Designed as a direct bolt-on replacement for the factory mounts, this set is ideal for sport and competition driving where precise drivetrain control is essential.

At the core of this mount set are Cusco's signature Hyper Rubber bushings, which are pre-pressed into the steel brackets for straightforward installation. Standard OEM rubber bushings typically measure 40–50 Shore degrees of hardness, while Cusco's Hyper Rubber compound measures 70–90 Shore degrees — delivering significantly greater resistance to both lateral and torsional stress without sacrificing serviceability. The result is reduced engine slop, more linear power delivery, and improved feedback during aggressive driving.

Key Features:

• High-hardness Hyper Rubber bushings pre-pressed into steel brackets for bolt-on installation
• Reduces engine and transmission movement and pitching under hard acceleration
• Hyper Rubber hardness of 70–90 Shore degrees vs. 40–50 Shore degrees for OEM rubber
• Improves throttle response and drivetrain feel at high RPM
• Designed for sports and motorsport driving applications
• Direct replacement for factory engine mounts — no modification required

Note: As with all high-durometer mount upgrades, a slight increase in NVH (noise, vibration, and harshness) transmitted to the cabin is normal and expected compared to stock rubber mounts. This is an inherent trade-off for improved drivetrain rigidity and performance feedback.
