Overview

The 3.9 final drive setup is an economical way of improving acceleration in the 350Z and G35. Increases available power by 10% per gear, resulting in faster acceleration in every gear. Professional installation required. Only for use on 6 speed manual transmission models.

Please note that in addition to the parts shown, there are also several sizes of side lash adjustment shims that Nissan offers. There is no way for us to determine what size(s) your car might need. The ONLY way to determine the proper size lash adjusters is during the installation by a competant installer. For those with higher mileage cars or who want additional peace of mind during the install, there is a list of optional replacement parts.

Available Gears

Below are the available gear sets. There are signifacnt differences in price, but that does not reflect quality. The price of the 350evo gears has not been thoroughly explained, but up until December 2005, they were the only gears available in the United States. The Central 20 gears have finally been imported and are of exceptional quality. Who knows, 350evo might be purchasing from Central 20 and reselling them.

The Nismo gears are new to market and are priced much higher than the other two brands. This is typical of Nismo products.
