MIA's Description

Over time, the original bushings can wear, leading to a sloppy transmission feel and imprecise shifting. This kit aims to firm up the transmission mount, restoring precision and stability.

Constructed from 85A durometer urethane, these bushings provide a significant upgrade over the factory rubber. They are sold as a complete set of four to ensure a comprehensive replacement.
