From usage in dozens of movies and TV shows over the decades to magazine project cars like the famed Project X (which itself was also a movie car at one time), their body lines and classic styling work well for everything from straight axle gassers to pro touring builds and everything in between. Thankfully, we offer thousands of parts to keep your tri five Chevy running and on the road no matter the build theme. The original engine and transmission fitted to the tri five Chevy had what some would refer to as “reverse motor mounts” with two mounts straddling the side of the transmission bellhousing area and one mount at the front of the engine. When performing a later small block or big block Chevy engine swap it is usually a good idea to upgrade from the standard single front mount to the later , which allows easier accessory drive fitment, but you need to add a traditional transmission crossmember to your ’55-’57 Chevy’s frame to complete the driveline support.

Crafted from 1-3/4-inch round tubing with .108-inch wall thickness and CNC bent for precise transmission location, heavy duty 3/16-inch thick end plates are welded on along with a 3/16-inch thick transmission mount pad. 1/4-inch thick frame brackets are included to accommodate allow for bolting the crossmember in. The frame brackets are position on the upper inside edge of the frame rails and used as templates for drilling the mounting holes required into the inner frame wall. Mounting hardware for the crossmember and frame brackets is included as well.

Then our crossmember bolts to these frame brackets. The crossmember is setup for standard two bolt GM transmission mounts. We offer both a standard , as well as a option.
