My thoughts are he's full of shit. I can think of close to zero situations where re-gearing diffs will be superior to xfer gears.

If you want to correct for tyres on road and dont do any off road work then yeah maybe diff gears. Though that's still going to cost you close to what xfer gears will be anyway.

Guess it depends on $$. u can get some cheap diffs sometimes. I could have got a pair of 5.12s for about 400 but did not get them as would not suit on road manners for 31's

Depends on how hard offroad u go. I have got 3.9s and 1L case with 31s. its fine for 90% of stuff i do. sometimes lower is better but $$ is a factor for me.

Are you installing them yourself?

Thinking about it not sure wich way to go if you go r, hoppers do you have rebulid transfer ? cheers

Diffs are going to cost you to have installed just the same as the xfer gears. If you want to do a rebuilt on your xfer with all new bits factor in an extra $300+ for parts alone. Diffs wont be as much in parts, but there are 2 of them, and it will almost certainly be more than $300, i'd be thinking closer to double that.

At the end of the day i'm sure diffs would be cheaper to do, but the xfer option is better value for $ IMO.

he probbably sells diff gears but not transfer gears. spend the money once get the transfer gears.

I wonder if the sales dude realises that when you put transfer gears in a Sierra transfer, you change high range as well as low...........

Just a thought

he did say r , hoppers only do low . cheers ron

If you are pulling the diffs as well to install lockers, the diff gears may be a bit more worthwhile .. otherwise the T/Case gears are the go .. (you will still want locked diffs to go with your gears )

The dude obviously doesnt know wat hes talkin about as the rokhopa does change your high range aswell....

rear is welded cheers ron

just put 5.12 in but i also put lockers in as well paid $500 for two frount vit difs replaced the r/p in the rear and bolted the frount vit dif straight in paid someone to set the pre load on the pinions then put then in my self. for the price of s3 hopper you can put two difs with lockers in but don't you want to get anywhere in a hurry the car will ring it box off if your not running at least 32's and even then i would go 33's on the road but off road 32's are great. it all comes down to give and take s3 hoppers willo give you more crawling ablity but the locker get you further. one other thing put birfield rings on the cvs

rockhoppers, u will lose 12%, that with a series 1 set, the next set u lose 21% i think

cheers thanks for that

ronoor .. what year is your Zuk ??

"""""91"""""

if you want to spend money on stuff that wont break than go diff gears.my rule of thumb is if you have 31's or taller than 5.1 is the way.if you have a 1 litre transfer than you will need 4.6 diffs.had many customers go to diffs after blowing transfer and finding theres no warranty.they also reckon having the gearing in the diffs gives better performance.in my yellow thing with 5.1 diffs i only use dual transfers when i want to show off,otherwise she does everything in single low and 5.1's.

Anyone know of a set of 4.6s for sale? or swap for a set of 3.9 or 3.7s?

Nic

what are the standed gears ???

Sorry but dual transfers's does that mean two transfer cases in circuit how is that done???

For your 91 it would be 3.7.1 i think. earlier models are 3.9.

Anyone got a top speed estimate If I put 5.12 vit gears in my zook with a 1L tcase & 31's. or top speed if I put 5.12 vit gears with 1.3 tcase & 31's?

u talking about top speed or revs at 100.

top speed and zooks dont really go hand in hand.

Edit: mine sits on 100 at about 3500rpm. with 3.9s,1L case and 31's

All day untill the police or a brick wall gets you

On a serious note the zook last week was between 100 and 110 kph on the Princess Hwy from Lakes Entrance to Mel four in side plus extra's for hours3-4 hours approx when you hit a hill back down to 4th when you get a red light 1st gear when you get a blue light then hit the NOS baBY

31 inch tyres with 1.3 transfer 5.1 diffs=4100 rpm at 100kh
31 inch tyres with 1 litre transfer 5.1 diffs=4500rpm at 100kh
i have the proper chart at my workshop and these are based on true tyre size not sidewall size.
