SuperPro Subaru S/Frame Void Filler Kit

Made with SuperPro's proprietary engineering-grade polyurethane, this S/Frame Void Filler Kit is designed to fill the empty spaces in your Subaru Forester's subframe. This helps to stiffen the chassis and improve steering response and overall handling. Unlike stock rubber bushings, SuperPro's polyurethane is unaffected by extreme temperatures, oils, or coolant, offering a longer service life.

This kit is a direct replacement for the factory void fillers, making installation straightforward. By reducing flex in the subframe, you'll notice a more connected feel to the road and improved alignment stability, which can also lead to more even tire wear. SuperPro has been developing suspension bushings for over 40 years, and this kit benefits from that extensive experience in engineering durable and high-performing polyurethane components.
