Neat RX-8 / FD RX-7 crown wheel and pinion – 3.63 (40:11) ratio.

Also suits some NC MX-5 / Miata models.

This ratio is perfect for a relaxed cruise ratio; those chasing top speeds; or more specifically for the extremely popular ZF 8HP auto conversions or other transmission conversions such as DCT or close ratio 6-speed swaps.

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.
