The drivers and couplers are made from carbon steel
aircraft alloy and are heat-treated for toughness and durability.
It uses standard gear oil rather than a special limit-
ed-slip differential lubricant.
It can be easily installed by anyone familiar with general
automotive work. With care, it can be installed without altering
the drive pinion and ring gear settings—they do not need to be
“set up” again.
It minimizes the tire wear that is associated with some
other lockers and also with limited-slip clutch-pack differentials
by allowing free rotation of the outside wheel during a turn.
It can increase gas mileage off-road in either a 4x4 or a
4x2 because of more efficiency due to increased traction, espe-
cially in sand.
It has been operated extensively off-road in some of
the most rugged trucks in the world—military and civilian—and
has been triple-checked for proper materials and design. We be-
lieve that it will last for as long as would your conventional open
differential.
It provides you with the best off-road traction available.
No other type of differential can match it in allowing up to 100%
of the engine power to be applied to either wheel even when the
other one is off the ground—the reason that the LOCK-RIGHT will
allow your vehicle to reach its maximum potential.
Front Axle Disconnect Operation
All modern 4x4 vehicles have a way to save wear on the
drive train and increase gas mileage by preventing the front dif-
ferential from spinning in 2WD. Some late vehicles accomplish
this feature by disconnecting only one axle shaft in the mid-
dle rather than by using free-wheeling front hubs. This design
saves cost by eliminating the need for the additional hubs and
full-floating axles. However, the differential gears continue to
wear. The LOCK-RIGHT can be installed in these axles; however,
the front ring and pinion gears will continue to rotate (the same
