90-110 and Defender Off Road Equipment
For serious off-road driving in the worst conditions, locking axle differentials are essential. This is because traction can still be lost altogether when a single wheel starts to spin. In this instance, all of the available drive will be transmitted to the spinning wheel. Locking diff's prevent this by allowing drive to be transmitted to the wheel/s which still have grip.
Locking diff's can be fitted to the front, rear, or for maximum traction, both axles.
We offer three types of locking differential, each with its own benefits:
1. Detroit Diff Locker. This is a fully automatic locking diff that is simple to fit and extremely rugged and dependable. It transmits maximum drive to the gripping wheel when traction is lost. However, due to the way in which it operates, it is recommended for fitting to the rear axle only.
2. Detroit True Trac. This unit features a gear-type limited slip design. Although not quite as effective as the Detroit Diff Locker, the True Trac can be fitted to front or rear axles without any effect on the steering. Locking is fully automatic and fitting is simple.
3. ARB Air Locker. This unit is a manual locking device and therefore only selected when needed, at the push of a button. The benefits of this design are that maximum drive is transmitted when needed and, when unlocked, the diff performs as normal. However, fitting is more complicated, requiring an air compressor to operate the unit. ARB Lockers can be fitted to front or rear axles.
