350z Z33 370z Z34 Z1 Motorsports 4.09 R200 Final Drive Ring and Pinion Gear

By far the most noticeable increase in acceleration and response comes from simply re-gearing the differential in your car. By changing the input and output ratio on the ring and pinion, the car is able to accelerate quicker through each gear. The Z1 4.09 Final Drive is a drop-in replacement for the factory ring and pinion, is compatible with all rear-wheel drive manual transmission differentials, and is available at a fraction of the cost of OEM gear sets.

Replacement bearings are required to install a new final drive in your differential. Through the product options, you can select to purchase all the required bearings and seals needed to re-gear your differential.

Included in the Bearing and Seal Kit:

2 X Nissan OEM Differential Side Carrier Bearings
2 X Nissan OEM Differential Side Oil Seals
1 X Nissan OEM Inner "Back" Pinion Gear Bearing
1 X Nissan OEM Pinion Crush Sleeve
1 X Nissan OEM Outer "Front" Pinion Gear Bearing
1 X Nissan OEM Pinion Oil Seal
1 X Permatex Ultra Gray Gasket Maker
It is highly recommended that an experienced mechanic install this ring and pinion gear set as excessive noise or even catastrophic failure can result from improper installation.
