Operation

The LOCK-RIGHT consists of two bi-directional over-run-

ning dog (toothed) clutches. Each one has a driving member (the

driver) and a driven member (the coupler, or in some models,

the existing side gear). Both clutches are rotated by the pinion

shaft(s) (or the spider). Each driver has special recesses cut in

one face that receive the shaft(s), and radial teeth cut in the op-

posite face (see Figure 1). Each driver mates with its coupler to

form a fully-locking combination, and the coupler also receives

the axle shaft to drive the wheels.

When your vehicle is moving straight ahead, both

wheels are rotating at the same speed and both clutches are

fully engaged (locked). When your vehicle begins to turn, the

outside wheel starts to rotate faster than the inside wheel. The

two clutches sense this difference in speed and allow the cou-

pler (or side gear) of the outside clutch to unlock so that the

wheel can rotate freely. It thus is “ground-driven” faster as

the vehicle is turning; power continues to be applied to the slow-

er (inside) wheel. As the vehicle straightens out the wheels again

rotate at the same speed, and the outside clutch re-engages.

This differentiating action occurs automatically for right and left

turns and in both the forward and reverse directions.

Features

Its design is simple and rugged. It is an automatic 100%

full-locking differential that is “all-gears”—no belleville washers,

clutch packs or cone clutches to break or wear out. The LOCK-

RIGHT simply replaces many of the parts inside the standard dif-

ferential case.

It uses your own stock differential case, bearings, pin-

ion shaft(s) or spider and thrust washers (and also the side gears

in some models) rather than parts that are all specially made and

therefore more expensive.

It uses stainless steel springs for excellent resistance to

high temperatures and fatigue.
