IAG STREET SERIES ENGINE MOUNT BUSHING SET 75A DUROMETER THE IAG STREET SERIES ENGINE MOUNT BUSHING SET The Street Series Engine Mount Bushing Kit is made specifically for IAG Subaru EJ Engine Mounts, and is compatible with Subaru EJ series engines for the 2002-2014 WRX, 2004-2021 STI, 2005-2009 LGT, and 2004-2008 Forester XT. 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 purchase one of our bushing kits to fine-tune your engine mount performance to either street-friendly or competition-ready levels. 75A DUROMETER BUSHINGS 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. *Does not include pins. Pins are available separately or reuse your original pins.
MORE BUSHING CHOICES AVAILABLE 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. For a more softer durometer, we also offer our new 55A comfort bushings.
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.
