Well short story here. Bought my first RZR about a month ago. New 2010 RZR S. I knew I would be going to the mud parks so I pulled the stock Bighorns and put on some ITP SS108 black wheels with 29.5 Outlaws skinny/wide combo. I read on here that they do not rub but my front left does rub some in certain turning conditions.....I could crank up the Fox's a little but gonna just put on a Racertech 2" lift and forget it. I wanted it waterproof to the HILT because of past machines I have owned. I would say I wasnt gonna go deep and then you got half a case of adult beverage in ya and you forget all that. I followed the directions on here on how to snorkel. They are VERY GOOD and after reading some install articles on aftermarket kits Im glad I did it. On to the vent lines. I put the Arctic Cat or CanAm accordian bellow thingys on the front and rear diffs to eliminate having to run those lines. I put a 'T' on the tranny and tcase lines to combine them to one and put a screw in barb in my clutch snorkel below the bed line. I ran the gas tank vent to the airbox snorkel and also put the screw in barb to keep it below the bed. The TB had a check valve on its vent so left it alone. Added a dab of silicon on the back of the speedo and put dielectric grease on all the electrical connections. AS for the radiator I ordered the billet cap from Rubber Down Customs but still have not got it in the mail. After many hours of racking my brain on the airbox I decided that a new box was in order. I really wanted the DFR snorkel box but at $500 bucks I just couldnt see that happening. I got the UMP and added the 6" rubber cap from Futuregarden.com. The only hitch I had on installing the UMP box was the clamp that went from the boot to the TB. It just was a little too big for the size of the lip on the TB.....kinda squished some rubber out. It worked but I think a narrower clamp would be better. I smeared silicon on both the box side and the TB side. Okay after all that we went to River Run in Jacksonville this past weekend and had a blast. Went thru everything I put it thru minus some bottoming out and having to get winched. Put it thru water up to my stomach and never had a hitch at all. Went thru a hole that a mud hole in 2wd that a Kodiak with Outlaws all the way around couldnt pull in 4wd. Overall I was really impressed with it. Put it in 4wd only a handfull of times just for "insurance" reasons. The rest just walked the dog in 2wd. Only things I wanna change on it is put some sort of stereo on it, UHMW skids, better CV guards, Racertech lift and a front bumper. Other than that I wouldnt change a thing. Sorry for the long rant....LOL!
