Our Summit Racing® steel transmission crossmembers allow you to run a true dual-exhaust system with most popular GM transmissions. They have a patented double-hump design, so you don't have to compromise ground clearance by running pipes under the crossmember, and they're a complete bolt-on deal--no custom fabricating or realignment is needed. They're made from 2 in. x 3 in. boxed tubing (1/8 in. thick) to handle the frame-twisting power of big blocks.

G Body G Force Crossmember Pretty Good

Summit RacingSummit Racing Verified Purchase

This cross member is well made and powder coated, looks great. A must for installing a 200r4 transmission in the '78-'83 G bodies, such as my '81 El Camino. Summit is awesome for buying from, very easy to deal with and super fast shipping. Only issue I have is with the cross member from G force and that is the frame extension piece included with this application. That extension should have included a vertical piece that ties to the bottom frame rail for added rigidity. As it stands I will fabricate and add that piece on my own. Other than that, buy this item, it is a fine crafted USA made item! ...read more
