Standard issue with the AlphaX suspension is tipped up rails.
For a very short period, we offered the AlphaX w/o rails for the '06-'08 Polaris sleds only to be used with stock rails or aftermarket (customers choice).
Last season we offered a limitted number of straight rails. It was never advertised on our site, just word of mouth. You would know if you had straight rails because you would have asked for them...
If you have our kit and dont know what rails you have, then we'll just assume yours are tipped.
