diff swap opinions

[dabawei]

What other vehicles are you running with?

Top speed may technically increase but the ability to hold that speed on inclines won't be better.

Other vehicle are other landrover series in this forum! I think it is Series-3.

I believe existing diff is 4.7 is it correct? Therefore if I upgrade to 4.12 would it give relax engine with 50Mph and hold on normal incline?
