The Mazda 4.44 ratio ring and pinion set is suitable use on the following rotary applications: 1993-1995 Twin Turbo RX-7, on some model FD’s the factory fit final drive is the 4.3:1 ratio acceleration can be increased by swapping to the slight;y shorter 4.44:1 Gear Set.
This ring and pinion set will increase your vehicles acceleration rate, trading a slight decrease in top speed in each gear.

A great modification if your not too bothered about trading a little acceleration for lower cruising RPM leading to a little better fuel economy.

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.
