It doesn't mean you have "lockers", it's just locked all the time. Its just 2 gears meshed together.
Companies call it different names, Final drive, rear drive gear ect.

Most are like the Eiger with a non-differential rear end. It does not make them tippyand dangerous - mostly because they are not very wide. Yes, one of the wheels will slip when in a turn - that's why ATV's are made for off road and not for pavement use.
One of the little Kawi's had a rear end dif - think it was the old 220. The slightly modified 250 probably still has the same rear end. They used to advertise it for utiility use on yards or golf courses. I think one of the old Yamaha Moto-4's had the same setup. There could be a couple more out there.

Yes there are atv's with differentials. Actually all irs machines have a diff but not all are limited slip. Polaris has an option on some of the quads to have a turf mode. This unlocks one side of the rear diff so it wont tear up the grass. A differential will have a ring and pinion. All IRS machines have a ring and pinion. There are just different setups on differentials but all are considered to have a diff.

Texasroadlawyer,
I dont recall saying anything about a solid rear axle so how was I wrong? I was talking about IRS machines. You have 3 different kinds of differentials. An open diff, limited slip and posi or locked diff. MOST atv's are locked differential. I am a certified mechanic and have been building 4x4 trucks for mudding and rock crawling for over 20yrs. Any time you need parts for the front or the rear it is called a differential nothing else! . A differential connects 2 seperate axles not one!.
A differential is a unit that takes the power of the rotating driveshaft at right angles to the rear axle and passes it to the axles. A differential will not only drive both rear axles at the same time, but will also allow them to turn at different speeds when negotiating turns.
.Just because it is or not locked does not mean it is not a diff. Yes you are right about the Outlaw it is chain drive and is not a true differential because there is no ring and pinion. A shaft drive is somewhat a diff setup but is not a diff because it still controls 1 axle.

Psycholic,
Before you put your 2c in you need to get your fact straight. Posi is not a Chrystler term it is a GM term. Chrystler called it sure grip traction!

I NEVER said posi was a locked diff. I said open diff, limited slip AND posi or locked!!! Thats 3 different kinds. Open diff being 1, limited slip and posi being 2, locked being 3. I have my facts straight!

OK maybe Im useing too much automotive knowledge and useing it in atv world. In automotive the final drive would be in the trans. This is the actual definition of the differential. It may or may not apply to atv's. It says a differential will drive both axles at the same time meaning locked or at different speeds meaning open or limited slip. I'll stay with my automotive definitions. If I am wrong in saying that all or most IRS machines have a diff I stand corrected but by going by the definition I still think they have diffs.

I've ridden one of the polaris 2 up atvs with the little pick-up bed/extra set deal and it had a turf mode switch which unlocked a rear differential. Really saved the grass in the yard and made the thing steer and handle easier I thought. Kind of a slick little deal if it didn't compromise the strength of the rear drive section.

The only two quads that have a rear diff, is one old bayou, and the polaris with box on back, im not aware of any other quad ( irs or solid axle) which have a differential in the rear. There are lots of irs quads which have a spool rearend ( outlander, outlaw, grizzly , kodiak, rincon and so on) in fact the only one which has a differential is that polaris .

A differential on an axle means one side can rotate at a different speed than the other side.

The kawie bayou 300 2wd had a locking rear differential.

common mis-use of the term. it should be called "final drive" or something of the sort.

my service manual calls it the final drive. it turns both axles at the same time, but not "also at different speeds"
the term "final drive" does not usually apply to the trans in heavy equipment, but the planetary on wheeled vehicles or gear reduction on tracked equipment. i suppose since it is the last gear reduction, "final drive" is the most proper, but rear diff is usually understood for what we are talking about.

The Jetmoto 250 hunter has a "open" differential in it. It works just like a car, the wheel in the air gets all the power and you dont move. It does make it very easy to turn though, and doesnt tear up grass turning either.

Hondabuster is correct about what a differential is...it allows wheels on the same axle to spin at different rates.
Jaybee is correct as well...there are very few ATV's with a rear differential...IRS or fixed axle...and like the Polaris (500?) it is for the purpose of not shredding the turf when you make a turn. 2Manytoys is incorrect, as all solid axle shaft drives also have a ring and pinion-based drive system, AND...I believe the Polaris Outlaw is a chain driven IRS without a differential.
The front is entirely a different(ial) matter, as many front differential units are in fact differentials that allow one wheel to turn at a different speed when going around a corner. Many times this means that one wheel will be underpowered when the front end gets stuck in mud (thus a 4wd is really just a 3wd)
A locking front differential does exactly that, locks both front wheels up with the drivetrain, making them both turn at the same speed at all times, which makes it tough to steer an ATV when it's locked up front

Please....skip the lesson...with the 4x4s you build, regardless of how you set up the differential, (open, posi, locked, limited, air locker, welded, etc) they NEVER have a solid axle in the rear (or front) that runs from one hub through the housing to the other.
So...what we're talking about is rear axles/drives, in response to MOTO's question.
Here's what you wrote
"Actually all irs machines have a diff but not all are limited slip. Polaris has an option on some of the quads to have a turf mode. This unlocks one side of the rear diff so it wont tear up the grass. A differential will have a ring and pinion. All IRS machines have a ring and pinion. There are just different setups on differentials but all are considered to have a diff."
Look again...you are directly asserting that there is a differential in IRS (and indirectly solid axles) when there is not one....a ring and pinion alone do not make a differential. Don't take my word for it, go to any online parts dealer and look at the schematics...any shaft drive, solid or IRS, will have a ring and a pinion gear. It's the spider gears and side gears that make it a differential, as they are what connect the ring gear to the seperate axle shafts
You also said
"A differential connects 2 seperate axles not one!. "
Now, if you take a moment to think about it, it makes no sense for an ATV company to build a rear differential in an ATV with IRS, since the rear wheels are turning at the same speed. And no, they are not all running two seperate axles into a housing. Once again, take a look at a schematic...say a Grizzly for example...There are no seperate speeds for either side because it has a solid axle running through the housing, with universal joints on each end.
Up front they are called "DIFFERENTIALS", because, by your own definition, there are two different axles that are turning at different speeds.
In the back they are called "REAR DRIVES" because there is only one axle (except for that special purpose Polaris you mentioned) that is being turned.

OK, a differential, (such as an ATV front axle), allows two drive shafts to spin at different speeds, so the name makes sense.
But if an axle, such as a live rear axle like a Vinson, or an IRS like a Grizzly, cannot spin their rear tires at different(ial) speeds, how can that be correctly called a differential? By locking a differential aren't you removing the differential? So can a simple ring and pinion rear axle is a "differential"? or is it a common misuse of terms? hmmmm

Actually, to be technical, the rear "differential" is actually called the rear drive, and the front is called the differential.
Posted by: v2rider
All irs models have a REAR DRIVE which looks identical to the front differential, and has the same fluid, and procedure to change as a front differential. Alot of people refer to it as a differential
Posted by: MotoF150
OK, stupid question, I had my 06 Suzuki Eiger jacked up on the rear axle and I noticed there is no differential, both rear wheels turn solid. I called the dealer thinking something is wrong with it and he told me thats normal and no ATV has a differential, I never knew that, he said thats the reason why they are dangerous and they tip over. Is this true? Is there any ATV with a working differential?

And POSI-traction was Dodges nickname for limited slip!
Posted by: Psycholic
And Posi is not a LOCKED diff as u described...It is a 'LIMITED slip' type---U could use some of your own '2 cent' advise!
