We received a few more Ring and Pinions in so there are a limited number back in stock on our on-line store.

MWSC heavy duty replacement ring and pinion for cub cadet garden tractors. The heavy duty ring gear and pinion both have extra long tooth length to increase contact over the stock one. They still have the same number of teeth as the stock Ring and Pinion. These Ring & Pinion are made in the USA
