The STI Hardened Gearbox Mount is produced by STI in Japan and has long been a valuable asset to any engine rebuild or form of chassis tuning.

Manufactured from a much denser rubber compound than the OEM mount, STI's homologated gearbox mount offers reduced flex in engine and gearbox movement, particularly under acceleration and hard cornering. The reduction in engine movement not only offers an improved drive through the gear lever but also channels engine power to the drive train more efficiently.

This mount is a direct replacement part meaning no modification is required.

For the more extreme vehicles we also offer our "modified" mounts which incorporate an additional rubber filling to limit movement even further.
