Transfer reduction gears with 5.1's.

[mooks100]

Gday all, I have 5.1 ring and pinion gears and am running 33's. I want to gear down the transfer case and am wondering which gears to go for. Calmini's are looking good but I dont but these all try to correct gearing in high range for tyre size when I have already done this in the diffs. I dont want to reduce it too much as it is my daily driver and I'd like to do some longer trips. Has anyone got 5.1's and say the 4.16:1 Calminis? How does it go on road/highway? I don't want to rev the crap out of it to do 100km/h. I like my 1.6 16v too damn much.

Cheers

you most likly to keep it from rev its head off on the hiway is to put bigger tyers on it or just dont go at 100km/h

Hey mate,

Just went through working out same thing for myself. (different ratio's though)
if you have the 5.1:1 Ratio in your diffs, there arnt really any commercial gears you can put in, that wont make you rev heaps on the highways...

If you've got 5.1 diffs with Calmini 4.16 Reduction Gears, and stock 1.3 5sp gearbox, you'll be doing 98kmph at 4500rpm... (there abouts)

if you put 35" tyres on it'll take you up to 104kmph @ 4500....

a 1l transfer case gives you a smaller about of reduction than commercial gears i believe, but i dont know any numbers for those, do a search maybe that'll help, also look in the bible under rocklobster, another home made way of gearing down....

Hope this helps

Thanks a lot. Will have a look

[muppet_man67]

have you thought about using 4.6 diff gears?

[mooks100]

Yeah I thought about it but have I'll stick with the 5.1's. A while ago I thought I saw a device, maybe on an American website like RRO or Petroworks or something which fitted betwnn your gearbox and your transfer case and effectively replaced your jack shaft. It left high range at 1:1. It had a lever and when you engaged it it doubled the reduction. Does anyone know of this and what it's called?

[Spike_Sierra]

what does you engine rev at when travelling at 100k's?

is your low range lacking(worse then stock with stock tyres)

[mooks100]

Think it sits at about 3200. Low range is about the same as stock

Trailtough products Rock Block.

Try http://www.trailtough.com/default.htm then click on the products link and look under drivetrain.

Sounds like an easy install, write up on iZook.

i think what you are talking about is called a klune - V sold by calmini

Here's the link to the iZook write-up on the Rock Block

but isn't the rock block for trailer queens only

[mooks100]

Had a read of the Rock Block info. Sounds good but says it's not suited to daily driver. Read up on the Klune - V, oooh baby, I want dat one. Emailed them for price and if they'd post to Aust. Fingers crossed. It sounds like the best option for me. Dont really want dual transfers and i reckon replacement gears would make longer trips hell. Guess it would be too much to hope for that there would be a dealer in Australia?

One litre is 12% high and low.

hey mate where did you get the info on the Klune ?
cheers Nick

[mooks100]

Googled Klune - V and up it came.

[zookjedi]

i hope your cashed up those klune's arnt cheap , i believe they come in 2 different ones is that correct ? the goliath and the david ? the david being the deeper reduction unit when engaged ? if this is the ones they are or were very pricey like well over $2000 i believe when i looked .

hope im wrong
goodluck and let us know

cheers Jai
