Transfer Box - 41D is a reconditioned two-speed transfer gearbox with a 1.2:1 high-range ratio and a lockable centre differential.

The transfer box mounts to the rear of the main gearbox and splits drive permanently between the front and rear propshafts through the centre differential, while providing selectable high and low range. The 41D designation identifies the 1.2:1 high-range gear set.

The centre differential can be locked, tying the front and rear outputs together so that drive is maintained when one axle loses grip.

Frequently asked questions

What is the IAB500100E transfer box?
The IAB500100E is a reconditioned LT230 41D transfer box with a 1.2:1 high range ratio and a lockable centre differential, fitted to the Discovery 2 Td5. It mounts behind the main gearbox and splits drive between the front and rear propshafts.
What does the differential lock do on this transfer box?
Locking the centre differential ties the front and rear propshaft outputs together, so drive is maintained to both axles even when one loses traction. This is engaged separately from the high/low range selection.
Which Discovery models fit the 41D 1.2:1 transfer box?
This unit is specific to the Discovery 2, built 1998 to 2004 with the Td5 engine. The 41D 1.2:1 gear set differs from the 43D 1.4:1 box used on earlier Defender and Discovery 1 models, so check your original unit's ratio before ordering.
