Outer Limits 4x4 Board

Just fitted up some 35's to my 80's range rover and high range is now very sluggish.
Low range still seems not too bad.

Can anyone recommend a fix for me please

I have been recommended possibly gears from a defender transfer case?

Shift to a lower gear.

4.11 diff gears

Hey mate, got your PM, will let you know in a few days about what your chasing, what year rangie or more particular what trans. has it got, cause if your still happy with low a transfer swap might be ok

more power and torque would fix it. 4.1 diffs would too. so would sifferent transfer gears (defender transfer if you are running a lt230).


Andy

best fix.

4.1 or 4.3 diffs.

Michael.

change transfer gears.quickest fix to help it get moving.

Go with the transfer gears
the gear sets dont wear much so second hand ones are worthwhile
It's cheaper than two 4.11 diff gear sets that usually have to be new
3.54 diff gears are maginally stronger than 4.11 and available easier
Do the transfer gears first , if your still not satisfied try more power it brings more smiles to the dial than gearing will for the money spent
Cheers

tran gears dont fix crawl ratio.

only halfa fix.

Michael.

4.11's will bring gearing back to normal

Ok so 4.11's sound like the way to go, what is required to change my diffs to this ratio? And could someone recommend where to get the parts to do this please thanks everyone for the replies

Well 2 choices, Rover 4.11 cw&p. Still stuck with a relatively weak set of gears. But if you have Maxi lockers and axles this would be the way to go.
Or
Toy conversion with 4.1 cw&p and Jacmac axles, a stronger set up im my opinion
just my 2c

I agree transfer is not the ideal fix but for a set of second hand gears, half a days work,a few litres of oil , $2-3 hundred you should be on your way.
4.11's front and rear minimum 2k.properly installed.
If you now have open rover diffs, then most would steer towards the toy set up. I'm not sure of their costs.
Maxidrive new with new 4.11 installed approx 3k an end.
Food for thought.

The defender gear set are a cheap option for road use, but like Micheal said, it's only a half-arse solutuion.

The Maxi-Drive 30% reduction low range is the best solutuion. It's about the same price as 4.11 CW&P set and only works in low which is where you want your ratio altered IMO.

With that set-up above, the total cost would cost you $2K if DIY, maybe a bit more if you have it fitted profesionally

The 4.11 CW&P set would give you roughly about 12% reduction overall in low and high from what I have been told.

Defender transfer cases are dear as poison but a good fix IF your still happy with low range

It high range that his not happy with you guys are missing the point...

4.11 ashcroft gears http://www.ashcroft-transmissions.co.uk/about.html good luck with the postage

or do a toy conversion... if you dont want lokkas then do a toy conversion as the diff as a whole is stronger... if u all ready have lokkas then get the ashcroft R&P

R & P

LRA $660.00 an end.

I dont think he can get the good ones anymore.. try jacmac as i was there a last week and showed him the ashcroft website as he was going to order some 4.11's for a client....

Mick

Awesome replys... thanks heaps

I am after some more in high range as I do a bit of beach work and
need the high range to really sing.

Havent given the low range a good work out since the 35's so i may still
be unhappy with that too on the hills... but in the mud and light hills its fine.

I think i will go with the 4.11 CW&P. Now just gotta find the parts.
PS probably going lockers soon too... or rear locked diff and front locker..
if that changes anything in terms of options for this gearing issue.

If you do a lot of sand work i would go the toyo conversion and get some 4.3 hilux/bundy diffs

4.1's are perfect on the beach with 35's

If you can weld, think about going gq front diff and 80 series rear, they come with 4.1's as standard and much stronger

He is running a LT95, when he is talking about transfercase gearing he is talking about a stage 1 LT95 we know of nice and cheap, his gearbox is in need of a rebuild. I have been told the stage 1 LT95 has lower gearing to the rangie one? if this is the case it would be a good cheap option and kill 2 birds with one stone, it wasnt to bad till he went from 33s to 35s and there still some problems with the motor to sort out which will get him some more low down yet.

How would the stage 1 LT95 go?

From what I've read on this site (and others) It appears to me that the Defender high range set and the maxi 30% reduction set would be the way to go. Add to that maxi axles and lockers, or jacmacs, and you'r well on the way to being pretty unstoppable.
Now, why would you be going for toyota changovers etc.? Is it cheaper and easier? I can't see it as being easier.......I maen pulling out a TC is really not that hard, and if you're prepared you can do it in and out in a couple of day no probs.

I'm Using 4,75 R&P from KAM and rolling with maxxis 35"*13.5*16 and i'm very happy with it.. stock lt230 and Zf auto... man for crawling its amazing...until know nothing to appoint..

I'm thinking do a toy conversion and maybe i go to the yukon 4,88 R&P or maybe 5.22 to the 37" tyres..

Cheers

Not sure about pricing in AUST, but I am assuming that you can easily get your hands on two Toy 3rd members with the gearing you want, better axles and install them for less than 1200 AUST $, no? If not less, then a wee bit more, but you gain LOADS...
