9" Ford 4.11 Ring & Pinion 37/9 Teeth IMCA UMP Figure 8 Demo Derby Street Rod U5

We have a used 9" Ford 4.11 Ring & Pinion 37/9 Teeth. I do not know the manufacturer. This is in good shape. It is standard weight and standard 28 spline on the pinion. Recycling one ton of cardboard saves over 9 cubic yards of landfill space.
