KAM Crown Wheel & Pinion Gear Sets

KAM offers a range of alternative ratio crown wheel & pinion gear sets.

The optimum final drive ratio can be selected to accommodate increased tyre diameter, up-rated engine performance and vehicle application.

The increase in strength is measured by using the standard 3.54:1 ratio as a baseline, calculating input torque produced by the engine power and output torque produced by the feedback into the diff from traction obtained.

Up to 25% gearing reduction coupled up with up to 70% increase in strength is possible with KAM lower ratio crown wheel & pinions.

3.54:1 is the standard ratio on all Land Rover Defenders, Discoverys and Range Rover Classics

Lower ratios of 3.8 ,4.1 and 4.75 are available

2.83 ratio is higher giving 28% increases in overall gearing
