Neat RX-8 / FD RX-7 crown wheel and pinion – 5.125 (41:8) ratio.

Also suits some NC MX-5 / Miata models.

This spicy morsel will really liven up your acceleration. Perfect for short course cars in motorkhana, hill climb or class circuit racing. Or maybe just a very fiery street car, whether naturally aspirated or turbo charged.

Stronger than standard OEM gears. EN36C case hardened steel, profile ground after heat treatment.

Don’t forget your diff rebuild kit to suit this crown wheel and pinion, available here.
