Ive heard mixed feelings...Lets just say money is NOT an option. Whos t-case gears are best? RRO, Trail tough, calmini, or petroworks (did i leave anyone out)? Let me know from personal experience... ~tx

Denton I have been there before, just not any good 4x4 spots.

I have personaly experienced 50k miles with a petroworks grs2,the only bad thing was a slight oil leak that HEALED itself.These new 6to1 gears are interesting <IMG SRC="smilies/biggrin.gif" border="0">

One of those new 6/1 would be nice, try and tell if it works so I can get one.. <IMG SRC="smilies/thefinger.gif" border="0">

yes, you did leave someone out....lol

these New Sumo 6.1's are first off "so strong" I bet you can't break them....
second just wait until you see the teeth on them, they are top quality.....and they run so quite!

we tested a set this weekend on the 2 hardest trails offered at the AZ Jamboree this weekend....both 4.5+....we did break an axle....(stock Zuk short side)

cool thing about these gears..we were able to jump out and be our own "spotter" without a worry of the Zuk getting away....bad part was watching the guys behind us slip their clutch to keep from running over us...lol

sold a couple sets too this weekend...some guys just loved the way they worked!

I don't anyone is worried about the gear, the think the issue is the T case itself. Also 2 trails is hardly a test. <IMG SRC="smilies/smile.gif" border="0">

7.5's have been run in the same case, just to see how strong the case is....it was modified to fit the gears....and it held up!

the t-case will hold up to the 6.1's...if you keep oil in it....lol

these 2 trails were a great test....we drove 100 miles just to get there with the gears..no trailer (yet)

ask around Lower Woodpecker and Axle Alley are plenty tough enough to see if the 6.1 Sumo gears are strong enough, and slow enough....

what test did you read about being done on any other t-case, or lower gearing before you got one?

I was amazed how quite they run...

I wish you could try a set and see for yourself how these gears work....but the line is too long to start handing them out for a test...:-)

Thats cool shit! kind of a "reach in, turn the key, and let her rip" kinda thing. Sounds like that could be the way to go now...Whats the going price for these things?

If money is not an option take a look at the Klune unit, goes between the Zuk tranny and t-case and gives you another 4 gears. Otherwise I'd try one of the new 6:1 gearsets, they are cheaper than the 4.89's.

Exactly what i was thinking!!

after a good nights sleep....from a long weekend of wheeling...I thought about this question and my first reply...

I know some guys add beefed up t-case arms when they use the GRS t-case gears....going the extra step to the 6.1's will also cause a little more stress to the arms....but I am sure the case will hold up to the pressure..

and if 2 trails over a 200 mile round trip are not enough...we'll keep testing these and keep you all posted how they work....

so far the things that have impressed me the most about the gears is how quite they run in low range and at full blast in high range on the road....put up against a 4.89 with the same tires and diff gears..the Sumo 6.1's are about the same speed in high range, but nice and lower in low range....

btw, (fatkid) did you see my neighbor in a BIG green Commando Jeep? he was with a few guys from Driven Auto Parts and their Broncos....
sure wish I could have went with them, and you could have drove my Zuk to test them out yourself...

for the love of gawd it's "object" people!
"money is no OBJECT"
iff'n it was "money is no OPTION" it would mean you were me,and had NO money <IMG SRC="smilies/pissed.gif" border="0"> <IMG SRC="smilies/thefinger.gif" border="0"> <IMG SRC="smilies/laughing.gif" border="0">

When it comes to testing something like a gear set or a running gear piece I was thinking more like a few thousand miles. And again I've never heard any doubts about the gears, I've heard people start to wounder how much the T-case can with stand before it comes apart. Anyhow where did you get your 6/1 and how much? <IMG SRC="smilies/smile.gif" border="0">

Hey Arizona Zuk,
Sounds like you got yourself a potentially popular product.
It's good that you have alot of people ordering these now. What you need to understand is, the people that are ordering them now are for the most part people that have more $ than wheeling experience. Those people will buy these gear sets and the hardest trails they will see will be TDS <IMG SRC="smilies/rolleyes.gif" border="0">
If you want to keep the orders coming you need some solid proof of all around strength and reliability.
Why don't you caugh up a set and let the TIN <IMG SRC="smilies/skull.gif" border="0">BENDERS give them the hammer test. We'll give you a fair test under normal "Hammer" conditions. After that we'll take em to the Rubicon and where ever else you want to complete the test. When we are done, I will write a product review on the results and get it published on any of the top 5 (.com) sites.
What do you think?
Want more orders than you know what to do with??
Independant testing is where it's at.
Our club has done this kind of testing before. Worked so good, the guy couldn't handle the results and had to sell the design to a bigger business to handle the volume.

Dave, i just put the 37" boggers on....How do you think that case will hold up in my rig??

Dtoys right test it at the Hammers, if it's got a weak spot it would show at Johnson Valley. But still it's going to take more than one or two runs, how about 6 months in this neck of the woods? <IMG SRC="smilies/skull.gif" border="0">

nice try...lol

we're doing just fine testing them in my Zuk....;-)

as for 37's (from another post) as soon as I can stuff stronger axles under my Zuki..I plan on going with larger tires too....I have no doubt these gears and case will handle hold up to whatever you want to power them with..the teeth are the same ones in the Indy cars..that push like what a thousand horse power? the Suzuki case has held up to 7.5's, but it has to be cut and welded to add the size of gears...and wouldn't be easy to market.

if anyone wants to try a set of these gears out..just bring your Zuk out here and we'll put them in and you can try them on some EXTREME trails we have close by....best I can do...but you have to bring them back..lol

we don't want to get too big and try to sell everyone a set.....want to keep the quality the way it is....

I just wanted to let ya all know we have them....they work fantastic....and the price is right....;-)

Well Dave, i gave you a call and left you a message....Would like to talk to you about these...Give me a call.

Thanks
Shane

Dave, just talked to Barry at 4 Wheeler Supply. He mentioned a trail in the White Tanks somewhere by the Zoo. Supposed to be a 50 foot waterfall you have to winch down
<IMG SRC="smilies/eek.gif" border="0"> , a couple mutiple winch obstacles and another spot where you have to use your winch to compress your rear suspension to fit under an overhang! With that kind of stuff in your back yard who needs to travel?

If that's the case you have the wrong hobby. Plan on spending at least a grand on gears at some point, and if your serious about rock crawling the lower the be$$er.

OK, if I ordered a 6:1 complete transfer case for $1150, when would you guys be able to ship it to me and how much is the core charge??
I tried to call but no one answered.

if the case splits is there any kind of warranty coverage?

If I had a winch I'd be real tempted, this axle swap is cutting into my winch fund. We could pull the targa and windshield off, along with the doors. Who's all going?

I sent you an email....

anyway...core charge on a complete t-case...is $250....can ship one out right away!

we just finished installing another set of Sumo gears for a local Zuki guy (Gary) he has stock ring and pinions..and 31's....dang is he going to be low geared on and off road....lol

If your an occasional wheeler you can get away with a GRS I, better yet buy the gears and put them in yourself, that runs about $400. I just know a lot of people who got the I and immediately wished they would have saved for the II.

is this a test question? oops I answered a question with a question..lol

"if the gears cause the case to split, we'll replace your case"

"if you break the case on a rock...we're not going to replace it"

I would recommend to everyone using a 4.89 or 6.1 to use a beefed up t-case mounting system....not just the beefed up long arm.....but one that bolt in more than the stock holes....

the Sumo gears aren't going to break the case....your u-joints or t-case mounts will break first....

that's what i was looking for. you said 7.5s were run in the case to see if it could handle it. will those be available? <IMG SRC="smilies/grinpimp.gif" border="0">

Alright I'm interested what and where and how much for the 6/1? What's the scoop? <IMG SRC="smilies/smile.gif" border="0">

In real life this probably doesn't matter, but If my calculations are right(I havent seen the gears) The 6.1 gears would use a 24 tooth input gear and a 60 tooth counter gear. any individual tooth on the input gear will only come into contact with 6 teeth on the next gear. This kind of gear set will not wear very good. Optimally all teeth in on both gears should come into contact with each other to ensure all teeth mate to each other and wear evenly-thus longevity. The GRS is an enginnered gear and has a long life. Which for me is not important since my sami is a trailer queen. I dont mean to say anything negative about another zooker stuff especially since i have not seen it or had long term test results. If some one could get me a tooth count, I may buy one! <IMG SRC="smilies/smile.gif" border="0">

tipover.....All your questions are good ones....I wouldn't want to just throw a $grand$ at a Zuki product without reading about how they worked for someone else....or see them for my self.......I am not Rocket Scientist......so my opinion of these gears is just that..."an opinion". However, I seek out people with products that are Qualified to engineer them correct....then I market their products for them....

The manufacture of these gears engineered them to the same quality and strength as the gears they make for the Indy cars...that put out 1000 plus horse power.....the teeth on the Sumo gears are plenty strong..we "Guarantee it!!" and they will back us up on that!

With the limited supply we are going to get of these gears.....because they are making lower gears for Sidekicks and Trackers for us too......This is an Inductry Offer on the 6.1's at this low low price.....in the near future our Sumo 6.1's will cost a little more.......you may want to wait until other wise shoppers have used them for awhile.....to see if they are what you want.

I am not that great at passing on what was explained to me about the quality and how strong the Sumo Gears are built....but I'll try......;-)

We are Zuki guys passing on top quality products at an affordable cost

one gear has a few teeth....the next gear has a few more....and so on..so on...so on....lol

I wonder if these have the same tooth count as the other 6.1's and how they are working here in the USA?

I sure would like Tim Hardy to try a set of our Sumo 6.1 Gears.....

who knows maybe down the road, ill swap in the kick tranny and case and have about 250:1!!!

the teeth are larger and stronger than the stock gears....you know the stock t-case gears that are used behind a V-6 Suzuki Lightning Conversion.....

the first batch is going out for a little less then the next batch....their $850 (eight fiddy) right now...just for the gears...after this batch is gone...we're going to make a buck on them....by raising the cost up to near what they're worth....LOL

first batch is gone, price just went up...:(

so, I want these gears but I still dont know who to call. Maybe I'm just a little slow. Arizonazuk, how about a clear precise, how to order post. Thanks and whats the NEW price.

Here you go, this is dave's website.

http://www.asianautopartsofaz.com/

$990 (from$850) I tried since monday to get him on the phone. Got ahold of him today and found out that the first batch sold out yesterday. I guess I should have ordered earlier but it took me a while to get my spare T-case apart to send him my core. Just my luck.

they are still under priced..and cost less than any other gears that low.....for now.....

we're not Wal-Mart..our prices aren't falling....the next batch of 15 gear sets is on a slow boat to us now....then in a few weeks, more will be on the way....

it's close to Christmas....let the little woman spend a few dollars on the kids this year...then get the gears in time for Moab....

I agree that its a reasonable price for what you get, its just that I am always a day late and a dollar short, everything I buy goes on sale the next day and I am always in the wrong place at the wrong time! Once I sell my GRSII I'll call you again.

Hey Dave, you can let me 'borrow' a 6:1 case for a few months.. I'll sure as hell test if for you :D
