xtra 10 vs xtra 12

I have an xtra 12 suspension on a yamaha ss440. Darn thing runns like a champ! But the problem is, one rail skid is broken nd the other is cracked. About to go any minute. Ill need to get both replaced either way. I found used ones on ebay for 55 bucks plus 20 shipping. Or can just get a complete xtra 10 for around 150 bucks. I think the xtra 10 would b a better ride for my sled but how much better? Is it worth thedifference in cash nd driving to pick it up. One more question would the track on the xtra 12 fit on the xtra 10?
Any addvise or opinions a greatly appreciated.

The Xtra-12 suspension is a "falling rate" suspension. As it compresses, it gets weaker, which is great for trail riding. It is designed for smooth operation. The xtra-10 suspension is a "rising rate" suspension and gets stiffer the closer you get to bottoming. It is designed to take bumps and abuse much better than the xtra-12.

Whether one or the other is better for your needs will depend on how you like to ride.

If the suspensions are designed for the same length track (usually 121", but sometimes 133.5 or 136") the track will fit either. Most single rider sleds had the 121", the 2-up sleds such as the Indy Classic had 133.5".

Check here for the donor sled, it should list the suspension length and type.
