WTB: 12 or 13 tooth pinion

Post by popeyet » Mon May 15, 2023 10:20 am

looking for a 12 tooth pinion to put in my roadster. Suppliers do not seem to have them in stock.

Thanks for the tips guys, I do have the recessed 40 tooth Ruckstell ring gear and I do have Rocky Mountain brakes. I With the lightness of the roadster and good running engine I think the 3.07:1 or 3:33 ratio will be what I want. I did find a 13 tooth.

Only trying to help. You know you need the recessed ring gear to use either of those pinions. Chaffins is a wealth of knowledge about this.

In the spirit of helping, a 13 tooth pinion will give a considerably higher diff ratio, and severely compromised braking. You will need auxiliary brakes for safety.
