Just a question out of interest for those of you with transfer reduction gears. With the 6.5 or even the 4.16, in low range what kind of speed can you do.

I am aware that 6.5 are something like a 260% reduction in low and 4.16 are like 80% reduction in low but how does this equate in real life to actual vehicle low range speed. (obviously tyre size comes into play)

I am not after a calculation of what speed it should or should not be able to do, I am after info from people who ACTUALLY have these gears in their cars and know for a FACT what speeds they do.

My reason for asking this is that I know of people that are contemplating going for 6.5's but use their vehicles for general purpose, i.e commuting, basic bush and some beach.

They read 6.5 this and 6.5 that and they think they need to have this wonder transformation. I may be wrong because I have not had them but the way I see it is that although 6.5's are awesome for crawling they would effectively make your vehicle into a high range only vehicle on the beach or anywhere else.

Can anyone shed some light ??

Id agree with you there mate. Another thing I have found is that in some situations ive had to 'rock' the vehicle out, using both forward and reverse. You only have 2 speeds in reverse (high and low range). High becomes clutch burning country and low gives minimal wheel speed.

I run 4.9's with WT diff gears on 30's. I can still do about 40-50kph in low between rough sections of track. Low first could be slightly lower for actual high traction rock crawling surfaces but overall I think its a great package for my DD and weekender.

i have found the opposite. with low reverse being so low i find that if i stop moving forward
i can idle out in reverse. the wheels move so slowly that they dont seem to lose traction.

also they are 190% lower in low range and 20% lower in high so ya dont need low range as much.

I have WT on MT 30's with 4.16's and a G16b and it is great, I use 2-5th low on the sand hills on straddie and it is perfect.
I have been on the beach with a sierra on 32's with 6.5s and it was crap, too much torque in low and kept on bogging down in the soft stuff & in the soft sand the 1.3 couldn't pull high. We spent all weekend digging it out, you can't slowly crawl sandhills...

will admit on the weekend that I had the vit ( g16b and 235 AT's) and the sierra over there, the vit did go better up the dunes ( running in low range), with stock gearing.

This may be a stupid question... but is there such thing as a transfercase flush? i've bought a TC with 6.1 ratios in there and just wanting to do some maintenance stuff to it before i put them on the zook. Sorry to crash the thread

i think 6.5s are to low for most people that are running 1.3 engines .. yes if you have the 1.6 the 6.5s are awsome u should be able to use high range 4wd on the beach .. but with out the 1.6 .. i find u are limited to what u can do .. like yer sure u can go on the beach .. but theres really no gear for it unless ur rev.. its Tits off .. btw im running 31s atm

what about 5.14.1 im trying to work out what gears to get at the moment i have 31s with nt diff gears and a g16b i had 6.5.1 gears but found them way to low. as jr zook said you get stuck in mud and your reverse is to slow but you have 3rd in forward

Twin sticks allow you 2 wheel drive low. So you can use your transfer case's low range and not have to use 4wd.

Twin sticks work nice for lockers, because you can shift to 2wd low for turns, and then right back into 4wd afterwards.

I do so well in 2wd low sometimes I forget to go back to 4wd, but I am harshly reminded when I try to climb a hill and the front tires are not turning..whoops.
