RE: After market shocks for hurricane XP or PRO
The shocks are just that. Shocks. They just dampen the impact. It's the springs job to push the rod back out.
As for stock oil wt. i think it's either 30 or 35. When i replaced my shock oil I got 45 wt. and i've been very happy with it. It's stiff enough for me to take jumps with but not so stiff that I can't stick my turns anymore.
If your chassis is hitting the floor when you drop it you may want to adjust the spring tensioner. On my car I just screw down a little collar and it compresses the spring down. I think on the hurricanes there's a plastic piece with a screw that you have to move down. I'm not really sure. But either way the concept is the same. Just make the spring shorter.
