3.94 out of 5 stars 16 Customer Reviews

Summit Racing™ Cummins to GM bellhousing adapters can facilitate a swap for your GM truck or SUV. Our kits include a billet aluminum adapter plate that's less than 2 in. thick and a steel flywheel. And, unlike OEM adapters, these allow your engine and transmission to be placed straight—not at an angle. They're available for different transmission models. When you want a clean install that's easy and will save you some room, Summit Racing™ Cummins to GM bellhousing adapters are the right choice.
