Only the 2001 will fit, and it would be a good idea to have it rebuilt, and have them replace the reservoir hose with a 250R type hose(the longer length of hose will give you more mounting options). Since those are rebuildable, you could have them resprung and revalved for your setup and save some cash as opposed buying a set of aftermarket shocks.Ī good one for the rear, if you can find one since they are getting pretty rare now, is the 2001 660 Raptor rear shock. But a good idea for saving some cash in the long run would be to get the 450R, YFZ450, or '05 style Z400 shocks. Your best bet is prolly to get a set of good +2 or +3 300EX control arms, find a relocator bracket, and throw on a set of 16.25 through 16.75 inch shocks(i.e. Ask roostin_dale, he'll tell you what he thought of the setup. Some people will say that it works, others will tell you that it doesn't. I also don't recommend doing the 400 a-arms on a 300. If I rememeber correctly, the axle carrier is about 2 inches wider than the 300's, so you would have some serious chain alignment issues. The 400 swingarm has a linkage for the rear shock and the 300 does not, so you would have to weld on a linkage mount to your frame, and then find a linkage to work, then have a custom shock built specifically for that setup. The swingarm won't, at least not without major modification.
