Innovative Mounts 90550-85A K-Series Conversion Engine Mount Kit 85A Bushings

The Innovative Mounts 90550-85A is a complete four-piece conversion engine mount kit engineered for K-Series engine swaps in 2001-2005 Honda Civic EM2 chassis. This kit features black steel construction with race-grade 85A durometer polyurethane bushings, designed to deliver maximum performance and driving response for manual or automatic K20 transmission applications.

Key Features:

• Complete four-piece kit includes driver, passenger, front, and rear mounts plus all necessary brackets
• 85A durometer polyurethane bushings for performance-oriented stiffness with acceptable vibration levels
• Black steel construction manufactured in California with strict quality control
• Eliminates OEM fluid-dampened mounts to reduce wheel hop and improve throttle response
• Designed specifically for K20 engine and transmission specifications

Technical Notes:

• Requires RSX/Civic Si (DC/EP3) subframe (rear crossmember) for installation
• Designed for K20 transmission; K24 engines require additional modifications including CR-V timing belt post mount
• Professional installation by a qualified mechanic strongly recommended
• Performance mounts may transmit slightly more vibration than stock depending on engine output

Innovative Mounts are built for performance driving applications where reduced engine movement and improved power transfer are priorities. These mounts remove the dampening fluid found in stock mounts, creating a more direct connection that enhances driving dynamics and shift quality.
