The front shocks are longer than the stock ones. Everybody has their own opinion on this but I discourage it, you take the risk of breaking your ball joints because they are going to be pushed further than they were designed. And if/when a ball joint does break you run the risk of getting hurt pretty bad.
The rear ones are also longer than stock, and 2002-newer ones have an offset piggyback reservoir that won't fit because of interference with the swingarm. The 2001's work but you have to figure out a new way to mount the reservoir because the hose is shorter than the warrior one. I didn't like the longer rear because it makes the back end sit higher which made the handling a little sketchy sometimes and it made it more difficult to keep the chain in adjustment.
