Hunterworks and Polaris Belt Dimension Info

This is information about why Polaris uses different belt dimensions on the Ranger and RZR 900 to RZR 1000. Hunterworks is working with an  belt manufacturer who will remain nameless on our own belts.  I have been talking with engineering extensively on this subject as we prepared to manufacture our own belts.  We have tested in the dunes in Calf., Moab and in the Southeast. We even bought a new 18 RZR 1000 test in house on, we have a Ranger 1000 too here.  A more detailed dimension article with pics can be found by clicking HERE

General and Ranger 1000 info updated: 6/2019

As of today we are adding our quiet thick belt to the application guide for the Polaris General and the Ranger 1000. On the Ranger 1000 this is the 17 models and the 18 crew only, so the old body style only. The new body style uses the same belt as a turbo.  This Quiet Thick belt might be come the belt of choice for these vehicles since most times they are not wide open machines, need the most belt grip they can get and want to get of the low speed squeal if you have it.

Turbo RZR

Let me address it first, the belt we sell is the thicker belt from the two OEM belts, the 16 model (thinner) and 17-18 Model thicker.  Polaris made a change in 17 to the thicker belt for better durability and we did the same thing in our belt but we are running them on 16 as well.  So you could consider our belt a HD belt for a 16 model and technically the 17 and 18 too as we are about .028" thicker in the cross section over the 17-18 belt.

Ranger 1000

This vehicle needs a special note too before we get started. The 2017 Ranger 1000 three seat and the 2018 Ranger 1000 Crew ONLY use the same belt.  The 2018 Ranger 1000 New style 3 seat and 2019 Ranger Crew new style use the same belt.  The 18 Ranger three seat and 19 Ranger 1000 three seat and 19 Crew use the 2016 Turbo belt.  Basically they have a totally new Ranger 1000 for 2018 but the new crew didn't come out until 2019 model.  

The belt for the new style is the same as a 16 Turbo, we will be using the 17-18 turbo belt dimensioned belt on this model, it will be thicker so I supposed would call it HD on the new style Ranger and it will grip this belt better too.

The old style Ranger 1000 gets our std belt talked about below which is HD for it.  

RZR/Ranger 800

Our 800 belt is equal in dimensions to the S belt 3211162 that considered the HD by Polaris for all vehicles that do not come with that belt.

Non-Turbo Belt Info

I guess before we start I need to give you a list of vehicles this information is about.

The following list is all models of every kind in each line. 

11-14 RZR XP 900
15-19 RZR 900
13-19 Ranger 900
16-19 General
16-19  RZR S 1000
17 Ranger 1000 and 18 Crew Ranger 1000
14-19 XP 1000 and XP4

Shocker, you can use one belt on every single model listed above if you want to.  The pulley or clutch diameters are the exact same on the primary and secondary on every model, the engine to transmission distance which is 10.5" is also the exact same on every model and the space between the two halves of the primary clutch are also the same.  If all of that is true, why does Polaris use different belts on each model? The simple truth is MONEY!! 

Example: A RZR XP 1000 compared to say a Ranger 900 belt cost Polaris roughly $4 more per belt, does not sound like much but multiply that times 100,000 then that is $400k, then if you put a XP 1000 belt on a Ranger 900 it would last a really long time.  There is a ton of engineering that goes into polaris's belts for each model to save them money. 

What Polaris is doing is making belts that are just good enough for each of the applications, keeping their cost down and keeping you buying their high profit belt. 

The actual difference between the belts is for the most part thickness.  The "Pitch Width",  for lack of a technical explanation, is the working part of the belt. All the above mentioned belts, the pitch width is the same but because they are thicker than the area below and above that line.  Read our Detailed Thicker Belt Tech Article for a couple pictures and deeper explanation. 

What we are doing, is to offer two different belts, one of them the thinner one will be very close to a OEM XP 1000/1000S belt in dimensions and we will use that one belt on every single model listed above including the XP 1000/1000S then ONLY for the XP 1000/1000S we will have a thicker belt also.

The thicker XP 1000/1000S belt will be great for high load vehicles, like big tires, rock crawlers, mud guys, slow riders etc. It is not for high speed riders, never run this belt longer than 1/4 mile at top speed as it might blow on you.   By making it approximately .050" thicker we can make it considerably more durable as in tensile strength.  One way these vehicles destroy belts is by crushing the belt, it folds inward, exposes the cord section to less pressure and you get what we call "cord fly out".  So by making it just that much thicker it holds up much better than the OEM belt in these applications.  In some in-house testing where we tested this thicker belt on a XP 1000 it held up twice as long in series of high stress controlled test.

The STD belt which is about the same as stock and thinner than the thick one would be for XP 1000/1000S who mostly drive fast, desert guys, duners, fast cross country types. This belt would be better for someone who knows they have a high heat situation too.  This belt is the right size for durability and runs cooler due to it being thinner than the thick one.

Just to make the decision on which of the two belts you should buy for your XP 1000/1000S simply consider this.  The Thick one will be the belt of choice for slower high load people and the STD will be for anyone who runs wide open or in the desert/dune to aid in cooling. We do not suggest you do any high speed or top speed riding with the Thick, can create too much heat and cause issues.  For all other machines other than the XP 1000/1000S the standard dimension belt is not standard to you and is thicker than yours so it will be considered HD for you and no matter what it will hold up better than your OEM. 

To be able to run any belt by anyone at top speeds I highly suggest you read this

Why you are blowing belts at high speed

As part of our in-house testing we installed one of our sample belts on a Ranger 900 and it made a very big difference on engagement, I was able to drive extremely slow up a pond dam in high range with no jerking.  The added thickness gave a ton more belt grip, which in turn increased the clutch to belt contact, it was smooth as butter.  Basically this belt will be overkill on all the models except for the XP 1000 and it will be equally as good and slightly better than the OEM Polaris belt for the XP 1000. I then installed one on our own Ranger 1000 and it did away with jerky starts and I was able to drive in low around 1700 rpm fully engaged.

I know so far in the explainations right above this, sounds like we are only talking about the XP 1000/1000S, not true.  The thinner of our two belts is still thicker than all of the models mentioned and will be considered HD or overkill for all those models.  Just for comparisons sake, I did a crude measurement on that ranger belt and the one I put on it, ours was .100" thicker so it will be considered very HD for that Ranger and the std one for the XP 1000/1000S. 

Hope all of this does not confuse you, just trust that Hunterworks has a good reputation, we have been doing clutching for 15 years and we will not put a bad product out there.  We are however the very first in the industry to do this for the Polaris line of UTV's, our belts are exclusive to us in design and dimension.  For comparison sake, Can-Am uses the same belt on 500 ATV all the way to a Maverick or at least they did up until 2013. 

We will still list belts on our site by vehicle to make it easy, ONLY the XP 1000/1000S models will have the choice of thick or standard. 

So here is the simple or short version, you can run our STD dimensioned belt on all those models, it would be considered a HD belt for all of them except the XP 1000/1000S or call it overkill for all of them but the XP 1000/1000S , we are not concerned about saving $4 here and we are not selling a 100,000 belts in a year, plus we are selling you our new belt for less than the OEM belt costs.  The thicker XP 1000/1000S belt would be considered HD on the XP 1000 and 1000S.  We simply want to be selling the best belt available period! 

We are not competing with other aftermarkets belts, we are competing with the OEM as they seem to be considered the best but no longer.

Also, our belts do not work with the Duraclutch due to ours and theirs being custom sizes and it needs the exact belt.
