I had Pitbull Growlers on my Rhino and they were awesome! Definitely not a pure mud tire le the outlaws ect. But if Bighorns are your fav's then your not looking or a mud tire. They did great in anything with a hard bottom and climbed outa holes better than any other tire I've had. On rocks and...
I haven't tried them but have heard good things about the axles Hunterworks sells. Price is really good compared to Yamaha. If you want bullet proof axles, Turners are the toughest, but you will break other stuff instead.
I had my last one installed at Hitch Depot in Red Deer. If I remember rite it was around $800 to cut off the bumper and build a new one that would handle the hitch. The did all the wiring too. Was pretty decent work. Done in a day.
I have a set of these doors that I used on my Rhino when I had it. They are built good and work well. I'll let them go for half what I paid if your interested.
I saw them too, Think they are crazy to be on there this early! lol Won't catch me on it until christmas. Way too many springs and open water to be safe on a quad or side x side.
