Mazda 4.777 Final Drive Ring and Pinion Gear Set for FD3s & RX-8

The Mazda 4.777 ratio ring and pinion set is suitable use on the following rotary applications: 1993-1995 Twin Turbo RX-7 and 2003-2008 RX-8,
This ring and pinion set will increase your vehicles acceleration rate, at the cost of a decrease in top speed in each gear.

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.
