i just put an 05 600 shock on my sv. all you need is the shock, and a . . . . .i believe 10mm x (fill in the pitch, i used 1.25) x 55 mm bolt. i could only find a 75, so i tightened her down (using red loctite, all i had at the time) and than used my dremel and chopped off the rest of the bolt pretty close to the threads and it cleared the dog bones easily. i weigh like 130 ish and i think the shock is a little too much at times. when riding over bumps, i frequently pop off my seat, i havent gotten around to adjusting the preload yet b/c i dont have a wrench thatll fit right on it, the sv one just slips off. over all, i think it was a good investment, 25 bucks for a brand spankin new shock. sorry for the ramble, im a little drunk already!
