Outer Limits 4x4 Board

Sorryb just re read your post! So does any body know what vitara diffs bring it down to? THANKS

Vit diff gears are 5.12:1 from memory. To calculate reduction multiply your drive line ratios. So for mine, its 3.65 (approx) for 1st gear X 5.14 (tcase low ratio) X 3.7 (diff ratio) = 69.4. Therefore my crawl ratio is 69.4:1 Overall. For a standard zook with 5.14 diffs, it would be approx 40:1, just less than S1 hoppers. Your high range 1st will be 22.51:1 approx with 5.14 diff gears. With crawler gears (say calmini 5.14) high 1st is 19:1 (approx). Does so with crawler gears you will have a slightly taller high ratio, and a much lower low raito ( comparing calmini 5.14 to 5.14 vit diff gears). I have used to calmini cause i have these and am pretty happy with them. S3 hoppers or S4 hoppers, or TT 6.5 Gears will give lower low range without much high range. If you want to drive rock, with 33's i would at least go the 5.14 or lower, as when i had the S1's (till i blew them up) on high traction rock i often wanted a lower gear ( i run 32x11.5 tsl/sx swampers, measure similar to a 33 MT/R). With the calmini gears i rekon the reduction is pretty good, nice slow crawl, but still enough flexibility to go get wheel speed without having to change up constantly.

Layto....

Thanks for that! I think i'll go for reduction gears for a lower low range.

About how much would you pay for a set? THANKS

When I can aford it I'm going these http://www.trailtough.com/transfercase_driveshaft.htm as far as I can work out these are close to spot on for 31's on the bitumen, and nice and low for off road.

About how much does that work out to Australian? THANKS

ABT sell these (6.4;1) for 1300 inlcuding new bearings and seals. works out pretty competitive compared to rockhopper which doesnt come with new bearings.

Is that fitted or not? Are they in vic? THANKS

highly doubt that would be fitted

Had a quick search and there all pretty much around the $1300 point. BBM has the serires 3 rock hoppers which reduces low by 170%

add 300 dollars for a transfer rebuild kit. series three is 6.1:1 the trailtough will work out cheaper and does not have the reputation for breakages that any rockhopper made product carries.

Do you really need the rebuild kit?

No, you don't NEED it. But it's very worthwhile doing, especially when spending so much on new gears they might as well get new bearings while the thing is in pieces anyway.

Yeah i guess so. Will shop around because i'm only on an app wage so i'll keep my eyes open. THANKS FOR ALL THE HELP GUYS

What about getting the trail tough 4.9 and the bearing kit from the U.S. if your on a budget.
Think that has everything you need, it might be missing a bearing and a circlip.
Should get the lot for about $AUD 900 plus what ever postage is.

i am definately going to go trailtuff

or if you are real tight...vit 5speed with transfer into 1.3l transfer case..gives you somewhere around 100 crawl ratio with WT 4.9's

WT is 3.7:1 ratio. 4.9 would be a non standard ratio. Dunno what vit 1st is, but would give approx 60:1 if you look at it like 3.65 1st gear, 2.1 vit low, 2.1 sierra low and WT 3.7 diff gears. Though plenty of flexibility too. Though unless you can do the work yourself the t-case gears are going to end up cheaper and easier.

On the bearing side of the question, for sure get new bearings if you are going to swap gears. Take not theat the calmini kit is not all bearings, just the needle roller bearings. Also fit a new shifter sheet as well (unless yours is brand new already).

Layto....

The trail tough gear set comes with shift sheet and seals, and the bearing kit from them is only us$89.

Does anyone know what is missing from the trail tough bearing kit, it has 2 less bits than the calmini kit, as I said 1 small bearing or bush, can't make out what it is, and what looks like a circlip.

The $900 dollar ones sound the way to go.

I don't really want to mix and match stuff i just want it done right the first time.

Will probably get them in a month or 2.

THANKS AGAIN

Don't know if u are convinced yet or not but i got 4.16 low reduction gears and the offroad performance is awesome. Followed by lockers at the same time. Now u have to actually try and get stuck. HUGE difference.

Yeah was going to go for the 4.16's when i do it but i've already got front and rear lockers so i have to try to get stuck anyway

anyone done the rocklobster on here, i've got my 1.3l gears out and 1l gears come out in a couple days then iam getting the gears swapped.

just wondering if anyone has any pointers or tips towards the counter shaft swap

cheers
