If your running 30" tall tires I'd recommend one of the better clutch kits, such as DDPs secondary with new springs and weights for the primary. Its been a while since I bought one but I believe that kit is around $600.00 . It will smooth out engagement, improve your low end power, and improve belt life. High will be much more useable. The best thing you can do is call Dale, he is very helpful in setting you up with what you need.
