Z1's Final Drive Differential Upgrade Kit includes everything you need to change your Final Drive Gear Ratio and Upgrade / Update your rear differential. If you are going to remove the differential why not only do it once.
Final Drive Gear Set
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.
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.
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 firstname.lastname@example.org for an installed price.
Differential Bearings and Seals
This kit is made up of OEM Nissan Differential Bearings and Seals needed when rebuilding your differential. This kit includes everything needed to make your differential like new when installing Ring and Pinion Gears and / or upgraded limited slip differentials.
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
Differential Cover, Fluid, and Bushings
With the Z1 kit you have new differential bushings, an improved Z1 Motorsports Differential Cover, and the best oil on the market. We even include a tube of ultra gray so that you have everything but the tools to complete the job.
When the stock rear differential bushing fails you often end up with a lot of slop and even clunking in the rear end. By upgrading to the urethane bushings you stiffen up the rear end to handle harder launches and smoother shifts. Plus with the upgraded fluid you don't have to worry about oil breakdown at higher temperatures.
Don't skimp out; do the entire kit with Z1.
Includes your choice of the following:
Z1, Energy Suspension, Whiteline, or SPL Front and Rear Differential Bushings (ES Bushings include Z1's Replacement Bushing Sleeve)
3 Liters of Red Line or Motul 75w90 or Motul 75w140 Differential Fluid
Z1 High Capacity Differential Cover
1 Tube Ultra Gray Silicone
Please choose the appropriate options below.
