Where can I find these aftermarket parts??? I can't seem to find any places on-line that carry them. Any suggestions?
The springs are available at your Polaris dealer, they are stock Polaris parts (albeit not for the 900).
The torque arm relocation is a modification, not a part. Info on how its done here: http://www.snowest.com/forum/showthread.php?t=364552&highlight=5%2F8+relocation
