There were a few different FOX shocks available for the Predator; I dont think any of them are as adjustable as the DS450 shocks.......One thing about some of the Pred shocks were that they were upgradeable with genuine Polaris (FOX) external ressi's.........that will just blow out the cost though.my friend has a predator and his stock shock fits the 700xx without modifing anything...they are fox not KYB... so here it is the girl question... what is the difference between these shocks and is it a bad thing to have to modify them?
