350z Z33 370z Z34 Nissan OEM 3.7 Final Drive Gears, Manual Transmission MT

For those of you looking for increased performance off the line we now offer this Nissan OEM 3.9:1 final drive ring and pinion gear set. These gears will fit 03+ model 350Z differentials, manual transmission model cars only, and will increase acceleration by roughly 12% over stock. This of course comes at a trade off of higher cruise speed RPM and decreased fuel mileage.
