Innovative Mounts B90650-75A-BA Billet Aluminum Motor Mount Kit K-Series 75A Black Anodized

The Innovative Mounts B90650-75A-BA is a black anodized billet aluminum replacement motor mount kit engineered for K-Series engines with manual transmissions. Machined from high-grade 6061 aluminum, this kit replaces the factory OEM rubber mounts with precision-built performance mounts designed to reduce engine flex and minimize wheel hop under aggressive driving conditions.

This kit includes 75A durometer black polyurethane bushings, rated for up to 250–400 horsepower, making it the ideal choice for street and track-driven vehicles that produce above-average power. The 75A bushing rating delivers a stiffer feel and reduced engine movement compared to softer street bushings, while still providing an acceptable level of NVH for daily-driven performance builds. The black anodized aluminum finish provides both corrosion resistance and a clean, aggressive appearance in the engine bay.
