Watson Racing's Mustang S550 TH400 Transmission Mount and Crossmember! When it comes time to step up to the Turbo 400 for high-power applications, we make the installation easy with our rigid one-piece transmission mount. The Watson crossmember is constructed of heavy duty 1/4-inch (6-mm) thick steel and zinc plated for long life – far better protection than powder coating which may chip off over time. Kit includes a TH400 rubber isolator/mount, and bolts in place of the stock transmission crossmember using your OEM bolts.Learn More
