Innovative Mounts 20253-85A Performance Engine Mount Bushing Insert 85A Durometer

The Innovative Mounts 20253-85A is an 85A durometer polyurethane bushing insert designed for use with Innovative Mounts engine mount systems. This high-performance replacement insert provides significantly firmer engine mounting compared to stock rubber mounts, reducing engine movement during hard acceleration, shifting, and cornering.

Key Features:

• 85A durometer rating for firm, performance-oriented engine mounting
• Reduces engine movement and wheel hop under aggressive driving
• Improves throttle response and shifter feel
• Polyurethane construction for durability and long service life
• Direct replacement for worn or softer durometer inserts
• Backed by Innovative Mounts limited lifetime warranty

Performance Characteristics:

The 85A durometer rating makes this insert ideal for track-focused and high-performance street applications. It provides minimal engine movement for maximum power transfer and precise shifting, though it does transmit more vibration to the chassis compared to softer 60A or 75A inserts. This stiffness level is recommended for dedicated track cars, weekend performance vehicles, or applications exceeding 200+ horsepower where controlling engine movement is the priority.

Application Note:

This bushing insert is designed to be pressed into compatible Innovative Mounts billet aluminum engine mount housings. It can be used to upgrade from a softer durometer insert or replace a worn bushing. The 85A durometer is significantly firmer than stock mounts and will increase vibration at idle and low RPM, but provides superior engine control for spirited driving.
