IAG Street Series Conversion Engine Mount Bushing Set with Pins (75A Durometer)

IAG's innovative engine mount design features the ability to swap bushings for street or track use, allowing you to adjust the bushing stiffness as your performance needs evolve. Instead of having to replace the entire mount assemblies, simply install the IAG Street Series Conversion Engine Mount Bushing Set to fine-tune your engine mounts to fine-tune your engine mounts to perform at either street-friendly or competition-ready levels.

Included in the Street Series kit are eight 75A durometer bushings that are slightly stiffer than the Subaru Group N mounts. These bushings deliver greater stability than the stock components, significantly reducing engine movement under heavy acceleration. Designed to enhance throttle response and facilitate a more direct power transfer, they are an excellent choice for high-performance street applications.

The IAG Street Series Conversion Engine Mount Bushing Set includes four replacement pins necessary for swapping the solid bushings in the IAG Race Series Engine Mounts to poly bushings. These robust steel pins, plated with yellow zinc for added corrosion resistance, securely hold and locate the 75A poly bushings in the mount carrier.

If you’re looking for a stiffer durometer bushing, IAG also offers a 90A durometer competition bushing that provides even more stability for high-powered engines. Also available are the IAG solid steel bushings designed to meet the demands of high-powered race applications. Due to the stiffness of the bushings, a slight increase in NVH (Noise, Vibration, Harshness) in the cabin is to be expected, as is typical with performance bushings.
