Thanks for all the replys. I've havent taken it out yet but just testing it in my yard I notice a difference. Its 3" wider in the front and 5" wider in the rear. Its now pretty close to the width of my Bombardier( sorry, I know I can't use that word on this site) . So as far as holding up we'll see in a couple of weeks in the dunes. But in the future no more spacers, I'll stick with wider rims. And as long as my wife doesn't get 5" wider in the rear I'll be OK.

 

You can get those valve stems from JC Whitney or ebay!

 

I went ahead and put mine on tonight. Took me and another guy about an hour and a half to get the spacers on. Only hard part was getting the races in the hub. I called NACs and asked them how hard it would be to put them on my raptor and he said I would not have any problems since the quad was new. Most people have problems when putting them on older quads. I got 6 inches in the rear and 4 on the front. Haven't rode it yet but I will Saturday

 

When you flip your front wheels, if you don't want to use flush mounts or can't get them, take the valve out of the wheel and install a new one with the stem pointed in. This will seal the hole. Drill the same size hole on the other side of the rim and insert a new stem. Now you can still fill your tire from the outside and if you want to switch back, just reverse the process. Just remember to use new valve stems every time you change.
