I was out riding today and saw 6 Firecats. I noticed that the front springs are different on some. Mine has the threads for adjusting at the bottom, where others are switched around and the threads are up to the top by the motor. Anybody know why that is ? I went to A.C. website and it shows that the correct way is threads down like mine is. 5 out of the 6 I saw today were the other way. Just wondering what that is all about. How is your sled set up ? Threads up or down ?
