Check out Eyeball Enginering in Las Vegas. Darrel races the pro class with the long travel arms and PEP shocks. He let me try it at Four Stroke Wars II in Glamis and they are like riding on butter. About $800 for the A-arms and than your choice of shocks.
Smitty
+2 A-Arms
i got the lone star +3 racea-arms with the standard +2+3off set wheel. i will have to pick the front end ofmy quad up to fully extend the a-arms to make it under 50". it's like 50 1/2 inches with the a-arms out level. my 250r has +2a-arms with the +2+3 wheels and it's 46 inches wide. both rear end measurements are 49 1/2 inches with 11' wide turfs. i had the same problem with my lower ball joints breaking on my laeger a-arms. i drilled and tapped the lower weak ball joint (volks wagon beetle tie rod end) and replaced it with a ricky stator 17mm ball joint. no problems since. my lone star a-arms already have the larger 17mm ball joints.
