3.72 Diff Ratio Crown Wheel and Pinion sets suit 80 series and HZJ75

This order is for a front and rear set together. These crown wheel and pinion sets come with solid pinion spacers for front and rear diffs. Our solid spacer kits come with shims to get the correct thickness or you can select a machinable spacer without shims that will need to machined to the correct length.

The diff ratio change is recommended for those with a manual transmission and performance upgrades in the following models.

HDJ80 / HZJ80 / HZJ75 manual transmission

These will provide a nice 10% drop from the higher 4.1 ratio fitted to the 80 series. This will give longer legs in every gear and lower revs on the highway. Towing is much more acceptable in 4th gear at 100kph.

Also worth considering is the mechanical LSD Torsen centres, which make the power delivery much better on and off road, while place less stress on your drivetrain than locking diffs.

Rear diff pinion is 32 spline (same as VDJ79) and front is 27 spline (standard).
