Reducing transfer ratio

Post by **suzuki boy** » Mon Sep 11, 2006 8:27 pm

As the topic says Is is worth tracking down a 1l box? Do they make a real difference? Is worth spending more for rock hoppers or those sorts of things? Went out with a guy with rockhoppers and i now notice how much i really need them! Any help will be greatly appreciated. THANKS

the 1 letre transfer is 12% lower

all its good for is to compensate a little for tyre size increase

crawler gears are worth every cent and youl save money in breakiage

your clutch will love u

and best of all when twin locked there isnt anything better

They do work well, but t-case gears would be better.

Mine is a 1.3 in a 1.0litre zook, so I have a 1.0 t-case
On 30's and 31's it was great, with my 4:1 stock diffs.

With the 32's is wasn't quite enough, so I fitted 4:9 diffs which is a touch low on road.

Price will determine if it is worth fitting.

If you never want t-case gears the older 1.0litre cases are cheaper and easier to get, but not as easy to fit. As most people want the newer type.

Well i got the front and rear lockers and now i'm up to the gears! I wont do the 1l thing if it only gives you 12% lower doesn't really seem worth it to me. A guy i was talking to said it would be the same as series 1 rockhoppers. But obviously not.
It was just that we were in rocks and he was ideling in first with no trouble on 31's (series 3) and i was on my 30's sliping the clutch and bouncing over them all!
Certainely need something. I don't mind paying for them i was just wondering if the 1l case did much. THANKS FOR THE HELP AND KEEP THE IDEAS COMING IN

he may have been talkin about the rock lobster

cheap series one low range gears using 1letre transfer and 1.3 transfer gears

RED_ZOOK done this a while ago search zook section there is some good information there from memory.

Thanks for that! I searched and that came up but it all seems like hard work from what the guy was saying it should just bolt straight in. I think i'll go for the rock hoppers. Can you get the series 3(apparently the lowest theyve got) any were or only the series 4? Thanks for the help

Post by **christover1** » Mon Sep 11, 2006 9:09 pm

I'd go for Marks 4wd gearmaster gears, good reputation and Aussie built.
I believe they are 5:1 and will be my choice on the next zook.
Next choice would be Calmini Gears from USA. I don't trust Rockhoppers anymore, too mant stories ( no proof tho

)

you may be able to find series 3 second hand

series 4 are supose to be toughter

i checked s3 to s4 and the gears didnt mesh so there definatly different

if i was to buy gears again id be looking at trail tought or calmini.

Post by **suzuki boy** » Mon Sep 11, 2006 9:19 pm

Will probably go for the marks ones or rock hoppers. What happens to the rock hoppers? Have heard the Marks ones are VERY good any idea on what there worth? Are the calmini ones cheaper, better, lower why are they good? Thanks again.

Post by **RB zook** » Mon Sep 11, 2006 9:26 pm

the marks ones are new and maby not had much long term test time thou could verry well the best out there.

calmini come in 4.1 5.1 and 6.5 to one

trailtough are 6.5 also

they all give round abouts 20% reduction in high range.

I used to have the RH series 1, but after a failure i now use the Calmini 5.14's Running standard WT diff ratio's and gearbox, they work great with 32 inch swampers. Have given them heaps more than i gave the RH's, and they have held up fine.

are there any australian distributers of calmini at the moment? or does everyone get them from overseas. I would prefer the extra after purches security that comes with buying something in Australia with a warranty. The marks hit is a bit pricey for the reduction it offers but if it turns out to be unbreakable then im sure it will attract many buyers. Rockhopper have a lot of work to do to rebuild there reputation.

I have the Series 3 Rock hoppers and so far they are working well, they are awesome to have makes for some fun wheeling and allows you to try so much more.

Nice little video! Looks like it was very close to going over!

The guy that had the s3's was ideling over the biggish rocks were as i had to really slip the clutch and bounce over them.

So do the reduction gears only come in the 1 ratio or are there different ratios like diffs and stuff?

Can you only get the calmini gears from the states? Are they cheaper or more expensive than rock hoppers?

Would the 5.14's be alright for 30/31's?

THANKS FOR ALL THE HELP GUYS

Post by **christover1** » Tue Sep 12, 2006 7:15 pm

common ratios for t-case gears are
4:1
5:1
6:1

less common
8:1

Post by **suzuki boy** » Tue Sep 12, 2006 7:23 pm

So witch one would you use for 30/31's?

Post by **RB zook** » Tue Sep 12, 2006 7:34 pm

i had 6.1 with 31's and it worked well

can always use second if you need to

better to have too much gearing than not enough

and when you decide you need bigger tyres you will be happy for the lower gear set

Post by **suzuki boy** » Tue Sep 12, 2006 7:42 pm

Was thinking exactly what you said! A bit lower and when i want bigger tyres i will not need to do gears again! Do you have any contacts for or info on the calmini gears? THANKS FOR THAT.

Post by **Nev** » Tue Sep 12, 2006 9:45 pm

when your mate said the 1L is the same gearing as a R1 he would have been talking about high range only. For high range they are both 12% lower but low range the 1L is still 12% whereas the R1 are about 90%.

When deciding which ratio to get for 30's/31's just look at the high range reduction. I run series 3 which are 22% in high and 170% in low on 30's. High range is fine..a touch low for highway cruising but you get by fine...low is awesome. with my 31 centis high range was pretty much spot on. Need to balance out an easy top speed for cruising against enough torque to be able to push those tyres up hills...my 31's were the upper limit for this IMO. I would be looking for something with high reduction of around 18-22% and as low as you can get....can never be too low..idle everything and always take 2nd 3rd or 4th up hills if getting too much torque and wheelspin

ABT, prob more but thats all i can think of ATM at work.

how can you tell if you've got reduction gears or not?

Do they make different diff ratio's for suzi's? As my mate bought his suzi already on 31's (i want to buy it off him soon), but doesn't know much about 4bys so he has no idea if it has gearing or not.
Gearing seems fine on road. Around town it feels spot on. But on the highway it maxes out at around 100. Cruises nice at 90-95...

Its a 95 WT 1.3 with exhaust/extractors...

low range isn't very crash hot tho. He has to ride the clutch. Alot.

Post by **MUD-PIGSIERRA** » Wed Sep 13, 2006 10:51 am

Put the 4by in Low range and First should be slower than walking, go up through the gears you shouldnt be getting any faster than 40kmh.

If low isnt crash hot, then my guess is not gearing mods, as with any crawler gears on only 31's it will be well noticable. You can get different ratios for diffs by fitting vitata CW&P or importing from states.

Iv'e been told from another thread in here that the vitara diff bits can be put into the sierra diffs even with locks! Is this correct?

Is it as good as reduction gears?
THANKS

Post by **lay80n** » Thu Sep 14, 2006 5:35 pm

Correct, as you are only replacing the Crown wheel and pinion, not the hemisphere that contains the lockers. But, the ratio is constant, as in it will only lower both high range and low range by a certain percentage. Where as crawler gears will lower you high range say 18% (allow for high range road driving with larger tyres), and also lower you low range by a much larger percentage (say 127%) so you can crawl much better. Depends on what you use the zook for, and how you like the car to drive.

I'm only 17 and an app carpenter so i'll probably just get a panel van or something! On road is nothing really as it will stay the same wont it?

Off road high is high so doesn't really matter how high it is!

If it drop low by 127% i think that will be the go! How much would you pay for front and rear?

THANKS

Post by **Oscars** » Thu Sep 14, 2006 6:28 pm

sorry if i missed it but what ratio is s1. as iam getting the lobster done in two weeks. cheers

Post by **munga** » Fri Sep 15, 2006 6:06 am

12% in high
76% in low
thats for 4.16's
and good luck getting a warranty with local stuff.
a few i looked at said no warranty, as its too hard to determine point of failure.
i ended up buying trailtough

That 127% is the low in a calmini 5.14 gearset (transfer gears). What im trying to say is that with diff gears, both your low and hi will drop by the same percentage, where as with transfer gears the high will drop slightly, which allows you to handle bigger tyres easier for road/trail driving. Your low will drop considerably though making crawling much easier and controlled (and your clutch happy too). I went for crawler gears before a diff ratio change, but then i dont intend to have zook diffs under my rig much longer

Post by **suzuki boy** » Fri Sep 15, 2006 6:54 pm

So that means that even high is 127% lower as well?

Is it better to just go for reduction gears?THANKS HEAPS
