I hear a lot of how pimp the ZPS system is and I've heard some about the Axis shocks. Both are suppossely Zero-Preload shocks. The Axis shocks are just as much or even more. Help

 

I can't comment on the ZPS shocks but I can on Axis. I have Axis fronts on mine and I have them set up for motocross. These shocks are top of the line. Their bodies and build is huge, way bigger than any other shocks. They are set perfect for me. They made my once good rear shock seem like crap now. Off big jumps it feels like they barely hit when the rear is bouncing back up in the air. I would highly recommend these shocks. I picked up my fronts for 800.

They will even send you a free brochure and stickers if you email them.
