Construction & Design

The Prothane transmission mount is engineered using premium-grade polyurethane, a material known for its exceptional strength and flexibility. Unlike traditional rubber mounts that degrade quickly under heat and stress, polyurethane offers enhanced resistance to cracking, tearing, and deformation. This ensures the mount maintains its shape and function over extended periods, even in harsh environments.

The mount’s design is a direct replacement for the factory part, allowing it to bolt directly into place without the need for drilling or additional hardware. This precision engineering guarantees a secure fit and consistent performance, helping to keep your Jeep’s drivetrain components properly aligned and stable.

Installation & Fitment

Installation of the Prothane Transmission Mount is straightforward and designed to be a direct bolt-in replacement for the rear transmission mount on Jeep Grand Cherokee models from 1993 to 2004. No special tools or modifications are required, making it accessible for both professional mechanics and experienced DIY enthusiasts. Proper installation ensures optimal powertrain stability and reduces unwanted engine movement.
