JHM S-Series Performance Motor Mounts – B8 S5-RS5 4.2L
Upgrade the drivetrain stability of your B8 chassis with the JHM S-Series Performance Mounts. Specifically engineered for the 4.2L powerplants, these mounts are the ideal solution for drivers looking to eliminate the common failures of factory fluid-filled mounts while maintaining a refined cabin environment.
The 3.0T engine produces significant torque that often overwhelms the soft, hollow factory mounts, leading to excessive engine pitch and eventual fluid leakage. Our S-Series mounts solve this by utilizing a solid, 50 durometer vulcanized rubber. This void-free design creates a much more stable platform for the engine, ensuring that power is transferred to the wheels immediately rather than being absorbed by drivetrain movement.
Precision Engineering for Audi Platforms
We’ve built these mounts to integrate perfectly with the sophisticated electronics found in the B8 and C7 platforms. Since many of these models utilize “active” mounts, our S-Series features integrated electronic emulators. These provide a simple plug-and-play installation that maintains communication with the ECU, preventing any “Active Mount” fault codes or Check Engine Lights (MIL).
Why Choose S-Series?
-
Solid 50 Durometer Rubber: Replaces the failure-prone factory fluid-filled “hydro-mounts” with a durable, solid-state alternative.
-
Eliminate Drivetrain Slop: Dramatically reduces engine movement during hard launches, heavy braking, and rapid gear changes.
-
OEM-Grade Housings: High-quality cast aluminum bodies ensure a perfect bolt-in fit with factory hardware.
-
Plug-and-Play Electronics: Built-in connectors replicate factory signals for a seamless, error-free upgrade.
-
Improved Shifting: Provides a more consistent and direct feel for both DSG/ZF and Manual transmissions (No engine bounce).
