Crown wheel and pinion set with a 4.1:1 final drive ratio for the rear differential, long nose differential configuration.

The crown wheel and pinion form the final drive stage within the differential housing. The pinion is driven by the propshaft and turns the crown wheel, transmitting drive through 90 degrees to the differential carrier and on to the halfshafts. The ratio sets the number of pinion revolutions per turn of the crown wheel and therefore the overall gearing between gearbox output and road wheels. Front and rear differentials must run the same ratio.

Crown wheel and pinion are lapped together as a matched pair and must be fitted as a set, with pinion depth, bearing preload and backlash set on installation.

Frequently asked questions

What is the KAM542 crown wheel and pinion set for?

It's a 4.1:1 ratio crown wheel and pinion for the rear differential, long nose diff configuration, forming the final drive stage that transmits drive from the propshaft to the halfshafts through 90 degrees.

Do I need to fit KAM542 with a matching front ratio?

Yes. Front and rear differentials must run the same ratio, so if you're fitting KAM542 at the rear, fit KAM541 at the front to keep both axles matched at 4.1:1.

Is this a direct swap for the standard differential internals?

No, it's a lapped matched pair that must be fitted as a set, with pinion depth, bearing preload, and backlash set on installation rather than transferred from the old components.

Which vehicles use the KAM542 rear crown wheel and pinion?

Fits the Defender, Discovery 1 (1989-1998), Discovery 2 (1998-2004), and Range Rover Classic (1970-1994) rear axle, long nose differential, at 4.1:1.
