Fitted a range rover diff to my landy earlier, yes just the rear one for now, disconectted the front prop too as its got a habit of popping in to 4wd and I didn't have the time to do the front diff.

What a difference! The gears don't run out after 40mph now :p It can sit on the motorway and over take things like a normal car! Makes you realise how noisey the tyres are now that you don't hear the engine screaming away.

I'm happy with it, makes it much more useable but then I've got a 200tdi in it, petrol 2.25 may not like the higher ratio too much. But then they rev higher than the 200tdi so aren't too fussed at motorway speeds...
 
I wouldn't fancy doing some decent climbs Wales in low range but i guess it suits your road needs it sounds good. The only option would be higher range ashcroft box and possibly an overdrive. i had the opposite my low range was too fast in crawling down chaplegate. Because of this i have fitted 4.7 ratio front and back in my 90 now I am fitting a higher ratio LT230 to get a higher top speed and all I can say is low range is now awsome.
 
My V8 used to scream it's nuts off with standard diffs in and I didn't use 1st gear on the road cos it set off in 2nd ok. Plus it kept blowing the crownwheel to smitherines so in went rangie ones and man what a difference, then the diffs were ok but kept poping halfshafts!!.So now I've got 300 tdi disco axles on which are same ratio as rangie but 24 spline and so far so good, must admit though I do like the loud pedal

i always thought the lightweight was actually heavier than a standard series and was only called a lightweight coz it could be easily stripped down
 
when i took my series to its first outing after i built it on a rangy chassis i didnt have time to do the diffs so it was on 3.5:1's and irt felt gutles, in low range it just didnt pull well enough. but thats with 2.25 petrol, i but i find i blow diffs more than a guy running the same setup as me, but then different tyres, ive got dumpers so loooads of grip. really its a good idea to look at tyres sizes, the bigger tyres will give you higher gearing, i expect if i ran 600/16s i could use rangy diffs, but with 34"s the gearing is that bit higher
 
Well I used to tackle even the steepest hills with my 265/75/16 tyres in 2nd gear in low ratio. So I can't see these higher ratio diffs making things too difficult. And right now the Landy is acting as a very capable van :)
 
Yea sounds good for you then I think NRG will probably agree sometimes you need seriously low for comps/trials and these diffs would set you at a serious disadvantage if trying to compete seriously. Steep hills you sometimes need 1st low just to get moving.
 
as above, when your climbing out of a small lake up a slope that makes your oil light come on.. thats when i was having trouble, i know thats pretty extreem, but doing equivilent to class two trialing you might be in a simular situation 5 times a day? at some sites, and that extra gearing realy makes a big difference :)
 
think you got some issues if your oil lights comming on! But agree serious hill climbing trialling CCVing'class 2 and turning on a hill decent requires really low gearing control is key. Lots of people say they use high range "off road" is bollix the most extreme terrain they have ever driven is probably a rutted driveway.nothing like trials comps
