I also have about 12 and a half inches of ground clearance

 

there is no way you have 12.5 inches of ground clearance unless you extended the swing arm alot!!!! theres not a lift out there to do this unless you built it your self, and if so it would be pretty cool, but i'd like to see pics. im thinking of doing that to my machine!!! just dont want to keep replacing u-joints!!

 

even if u extend teh swing arm u're not gunna get a complete 12.5 in of lift, u'll still have a solid rear axle with the same clearance as when u didnt lift it. to get an actuall 12.5 clearance u'd have to have irs. here is one. enjoy bad a$$ foreman
