This transmission mount was designed for a 2004-2006 Pontiac GTO and 2001-2005 Holden Monaro with a manual transmission.
Revshift polyurethane transmission mounts are made in the U.S.A. from high grade polyurethane and 6061 billet aluminum.
Revshift mounts are the most durable and reliable mounts on the market. CNC machined billet aluminum flanged ends are embedded deep in the urethane which prevent the isolated ends from separating under extreme loads. Utilizing class 14.9 alloy steel removable screws, these mounts will hold your transmission in place for a lifetime. To further ensure the strength of these mounts we form the threads with a forming tap which creates denser and stronger threads in the billet aluminum ends pieces.
These mounts have removable screws for ease of installation. We recommend using loctite on the threads during installation.
80A black: Slightly stiffer and stronger than OEM rubber. No additional NVH. Great choice as an upgraded stock replacement (OEM+).
95A green: Significantly stiffer and stronger than OEM rubber. Minor increase in NVH. Excellent for enthusiastically driven street cars and track cars.
70D teal: Drastically stiffer and stronger than OEM rubber. Moderate increase in NVH. Most commonly used on dedicated track cars.
(NVH = noise, vibration, harmonics)
