Here's some smart bolt-on protection for your 74ci or 80 ci Harley-Davidson with the stock banana style rear brake caliper, rear disc brake. This bracket will give your ride more miles with less hassle. This 3/16 inch thick bracket replaces your bent rear axle flat washer and puts even pressure on the swingarm to keep the right rear axle adjuster from jamming. Approximately 26 pounds of spring pressure on the caliper keeps it from bouncing, even on the big bumps. Nylon insert in the spring ensures minimum wear on the caliper. Reduces rear disc brake pin and bushing failure. Fits Big Twin 1973-1980. Chrome plated.
