1. They COULD perform better than the stock Fox Shocks
2. They will cost a SHIT TON of $$$
3. They will give you bragging rights
How badly do you want to spend more money?
Nah it's not a COULD...it's a WILL. Increased fluid capacity and better internals (valving, piston, etc). It'll be a solid upgrade guaranteed. It's also guaranteed they'll cost ya, but it's all about how hard you're pushing the truck.
