Summit Racing™ Cummins Conversion Crossmembers

Summit Racing™ Cummins conversion crossmembers are specifically designed for installing a Cummins 6BT into your 1973-87 Chevy 4WD truck or 1973-91 4x4 Suburban. These drop conversion units often eliminate the need for a lift kit. They're a direct bolt-in, utilizing OEM hole locations, yet still allow room for drilling and adding additional bolts for increased rigidity. The crossmembers are made from high-quality steel with a black powdercoat finish. It's a fact—any conversion can be tricky. Thankfully, Summit Racing™ offers the correct components to help you get the job done right!
