Innovative Mounts 90630-85A Rear Engine Mount with 85A Race Bushing

The Innovative Mounts 90630-85A is a performance rear engine mount engineered for 2002-2006 Acura RSX and 2002-2005 Honda Civic Si models equipped with K-series engines. This replacement mount delivers enhanced stability and precision for performance-oriented driving applications.

Key Features:

• 85A durometer polyurethane bushing designed for race use
• Solid steel construction with durable powder-coated finish
• Eliminates OEM fluid-filled dampening chambers to reduce wheel hop
• CAD/CAM designed and stress-analyzed for optimal performance
• Black bushing color distinguishes 85A race specification
• Replaces OEM part number 50810-S7C-003
• Backed by manufacturer's lifetime warranty

This mount provides a more direct connection between engine and chassis compared to stock rubber mounts, improving throttle response and reducing drivetrain movement during acceleration and shifting. The 85A bushing firmness is specifically intended for race applications and will transmit more vibration than softer durometer options. Professional installation by a qualified mechanic is strongly recommended.
