When installing a Cummins 6bt into your 1973 – 1987 Chevy 4wd, this 2″ drop crossmember allows proper placement of the engine which often eliminates the need for a lift kit. This item will also fit Suburbans up to 1991 models. This drop crossmember is a direct bolt-in utilizing OEM hole locations, but allows room for drilling and adding additional bolts for increased rigidity.
