Differential Final Gear Set

ATS final gears are shorter than the stock finals (except for the one for Nissan R35 GTR) and provide faster acceleration for each gear.

A shorter final gear is especially beneficial for a vehicle of lower engine torque. On the other hand, the longer final gear for Nissan GTR with the gear ratio of 3.333 is designed for higher top speed.

An appropriate final gear will present significant advantage on many competition events and races.

For the greater durability, special shot peening (ATS Temper Shot) and heat treatment are applied to all ATS final gears.

Note: In exchange for a faster acceleration, the vehicle top speed is reduced according to the shorter gear ratio.
