rear axle. Fully automatic 'Detroit Locker' type to suit Rover 24 spline differential

The Detroit Locker is a fully automatic locking traction differential that is well known for premium performance and dependable operation. Preload devices between the side gears deliver 100% torque and power to both drive wheels yet unlock automatically to permit necessary wheel speed differentiation. The Detroit Locker is trouble-free as it does not require service adjustments or special lubricants. Easy to install, no special tools or case modifcations required.
If a 'Detroit Locker' limited slip differential is installed in an axle casing with imperial dimensions, the following items are also required: 1 x distance collar ring 555471, 1 x sleeve kit 555472 and 2 x tapered roller bearings 361783.
The differentials of the Rover rear axles were converted from imperial to metric dimensions around 1983. This can be checked by looking at the bolt heads of the shoulder bearing blocks. If these are labelled '8.8', it is a metric differential. If the bolt heads are not labelled, it is an imperial differential.
