I removed this helix from my last sled thinking it would fit on the new one, no such luck. I purchased this as a kit last January and ran it for Three months before I put the sled away for the winter, it is in excellent condition. I am keeping the primary spring, pins and weights as I plan on purchasing DJs S8R and installing it in the new sled. This Helix will fit 03 to 06 Ski Doo 600, 700 and 800s with the button secondary. Asking $ 140 plus shipping or will trade for DJs S8R in comparable condition. I am located near SLC, Utah.
