Low Range Gear Set – 85% (3.743:1) Reduction to suit Patrol GQ / GU

Marks 4WD Adaptors manufacture low-range reduction gears to suit your Nissan Patrol GQ and GU. These gears are manufactured in-house at our facility in Melbourne, Australia.

We make four different reduction ratios that suit different vehicle applications and requirements. These gears will suit both automatic and manual vehicles.

The 85% reduction gears give you the biggest reduction we offer. These are mainly suited to rock-crawling vehicles or vehicles that are prone to run away downhill (fitted with an automatic transmission).

As an example, this reduction gives a manual vehicle about two full gears below where the factory gearing sat.

The maximum speed in low range will be approximately the same as the third gear with standard gearing.

The high range is not altered when fitting our low-range gears.

To calculate your vehicle’s speed using different ratios, click here.


As the installation requires the transfer case to be disassembled and the reuse of bearings, it is a good time to do a transfer case rebuild. We also offer the full-bearing and seal kits
