White Washer Info, all you need to know!!!
We now have two white washers, the STD washer and the Thick washer. The std washer is to be used on every belt sold including OEM, our STD belt or any aftermarket belt you want to fix the inherent issue of belt overtravel except for the Gates brand it is too short for it to fix. For more info on belt overtravel, here is the complete article on that. Link to Overtravel Article
The STD washer is the only one you can buy off our site separate because you can use it with other belts as mentioned. The Thick Washer is only to be used with the new Quiet Thick belt and it comes with it so no need to sell one of them.
The Thick washer is ONLY to be used with our Thick Quiet belt because we intentionally shortened and widened it to spread the secondary clutch apart a fraction of an inch to stop the low speed squeal in some secondary clutches when you use a thicker belt.
The STD washer now comes with our HW-921K belt which is our STD belt used on most of the RZR's, Rangers and Generals. All have a overtravel issue so it is best to use the washer. I will say it is not 100% required with our STD belt even though it ships with it but if you are doing any high speed riding or high rpm in low range riding it could save your belt from the overtravel issue I mentioned earlier and linked to.
Why do other aftermarket belts not come with washers? Truthfully, they just copy what Polaris did on belt dimensions and you have to know they just got it wrong same as Gates has the XP 1000 belts and some of the other belts that the part number ends in 4140 or 4157, they are too short and blow pretty quick at higher speeds and pull inside teeth off.
The washers purpose is to allow us to make and use a belt that fixes the overtravel issue and low speed squealing coming from these secondary clutches all the while of allowing you to run a thicker belt that grabs better than the OE belt on most models.
