Stock Description Below
For those of you looking for increased performance off the line we now offer this Nissan OEM final drive ring and pinion gear set. These gears will fit 03+ model differentials, manual transmission model cars only, and will increase acceleration. This of course comes at a trade off of higher cruise speed RPM and decreased fuel mileage.
We offer an installation kit that contains all new Nissan OEM bearings and seals. We highly recommend the purchase and use of this install kit. Please note that installing a ring and pinion requires precision setting of the bearing pre-load and clearances to complete the job. When installing be sure to keep the factory shims in their respective locations. Shims should not need to be changed.
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. If you would like to have your gear set installed at Z1, please contact us at email@example.com for an installed price.
Please choose the appropriate options below including our Full OEM Differential Bearings and Seals Kit for all the additional parts you'll need to complete the install.
