4.44 Gear Ratio Ring & Pinion Set (M054-27-110A) - NLA

No Longer Available.

Fits cars with short pinion shafts:

• 79-85 Rx7
• 94-97 Miata

86-91 RX7 Non-Turbo Ring & Pinions: The 4.33 ratio gear set is the lowest gear set available for 1986-91 non-turbo RX7s.

To obtain an even lower gear ratio (4.44, 4.875, etc.) requires grafting (splining and welding) of a short pinion shaft from an early (1979-85) RX7 to the end of an (1986-91) RX7 non-turbo long pinion shaft. This is very complicated and should be done only by qualified machinists.
