Innovative Mounts 90830-85A Replacement Rear Engine Mount with 85A Polyurethane Bushings

The Innovative Mounts 90830-85A is a high-performance replacement rear engine mount designed for 2006-2011 Honda Civic Si models equipped with K-Series engines. This performance-oriented mount features 85A durometer polyurethane bushings that provide significantly firmer support than stock rubber mounts, effectively limiting engine movement during aggressive driving.

Key Features:

• 85A durometer polyurethane bushings for track and competition use
• Laser-cut and formed steel construction with rigid welded design
• High-quality powder coat finish for corrosion resistance
• Eliminates dampening fluid found in OEM mounts for improved response
• Reduces wheel hop and improves power transfer
• Direct bolt-in replacement for OEM part 50890-SVB-A02
• Backed by Innovative Mounts lifetime warranty

The 85A bushing stiffness is recommended for high-performance street cars, drag racing, and track applications. While these mounts provide superior engine stability and driving response compared to stock, they will transmit more noise, vibration, and harshness (NVH) into the cabin due to their firmer construction. This mount is ideal for enthusiasts who prioritize performance and precise shifting over comfort. Professional installation by a qualified mechanic or automotive specialist is strongly recommended.
