Description
Product Overview
The Prothane 7-1604 Red Urethane Transmission Mount Kit is a purpose‑built component designed to replace factory‑installed mounts on a wide range of 6‑ and 8‑cylinder vehicles. Manufactured by PROTHANE, a reputable name in performance‑oriented automotive parts, this kit features a high‑density urethane body that absorbs and dampens engine and transmission vibrations far more effectively than traditional rubber mounts. The painted exterior not only adds a sporty visual cue but also provides an extra layer of protection against road grime, UV exposure, and chemical contaminants. Weighing just 1.55 pounds, the kit is lightweight yet robust, ensuring that the added mass does not negatively impact vehicle dynamics.
Usage
Designed for both street and track applications, the Prothane mount excels in environments where vibration control and component longevity are paramount. Whether you are a weekend racer looking to fine‑tune chassis balance, a daily commuter seeking a smoother ride, or a shop performing a performance upgrade, this mount integrates seamlessly with existing drivetrain assemblies. Installation is straightforward for anyone with basic mechanical skills, and the kit includes all necessary hardware to complete the swap without additional purchases. It is especially beneficial for vehicles that have been modified with higher‑output engines or aftermarket transmissions, as the enhanced damping capacity helps to mitigate the increased stress on the drivetrain.
