Hi there,

there is a Defender with 280/85-16. The transmission ratio needs to be lowered.
And I think that a 4.11 Diff-ration would do that nicely.

But what do you think about the strength of these gears. Commonly a diff with a low-ratio is weaker due to smaller teeth or so (that�s why the Rover 4.7 are no option).
The british company KAM say (on their homepage) that the 4.1 diff is 25% stronger than the OEM gears.
How can they know ?
Anybody had these gears and couldn�t recommend them ?

Alternative solution could be to use the t-box of a 2.5lDiesel Defender with 1.667:1 high-range ratio. This would leave the low-range relatively high - ok, then we use the Maxi-drive (straight-cut) gears that have a about 30% lower ratio than the OEM�s 3.32:1 . No concern about strength then, but at what expense views hopefully awaited.
REgards,
Hendrik
