Our Summit RacingĀ® 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.

My original crossmember was not rusted through, but I have seen a number of cases where rust had depleted the mount strength significantly. ...read more

Well made product but doesn't fit

Summit RacingSummit Racing Verified Purchase

I ordered the cross member for my 1971 A-body chevy. According to the product description the product should fit my car but it was not wide enough. I had to return the product for a refund.
