The Mazda 4.444 ratio ring and pinion set is suitable use on the following rotary and Miata Applications: RX-2, RX-3 SP, 1979-85 RX-7, and the 1994-01 Miata.
Alternate axle ratios are available for special applications. These ratios interchange exactly with the stock parts and should be adjusted to stock specifications (except as noted on the information sheet supplied with the gear set). If you replace your existing gear set with a lower ratio (higher number) gear set you will increase the vehicle”s acceleration and move through the transmission gears quicker, but you will simultaneously reduce the top speed of the vehicle for a given rpm limit. However, if you reduce your existing gear set with a higher ratio (lower number) gear set you will decrease the vehicle”s acceleration and move slower through the gears, but the top speed of the vehicle will increase for the same given rpm limit as in the previous example.
Note that the RX-3 SP uses the same gear sets as the RX-2 and RX-7, while other models of the RX-3 have a different selection of gears. The pinion shaft is longer on the conventional RX-3.
Please Note: This part cannot be returned for exchange or refund due to its fragile nature and possible customer mishandling.
