I went out of my comfort zone and got Fox 2.0 C shocks (HD) for my 800LE (50"). They suck up rolling terrain like PacMan, but in slower situations where there is a hole, or just over the top of a sharper bump, or protruding rock, the front end often goes CLUNK! I should mention that I removed the front torsion bar after it broke, and intentionally got these heavier springs and valving to supposedly make up for it.

I ride trails in a spirited manner, but rarely, if ever, leave the ground completely; lots of zero gravity, but no real jumping.

I reduced the supplied spring preload a bit, and increased the damping, which seems to have improved things. I’m thinking that rebound damping is the problem, and that these shocks/springs are snapping back too quickly after experiencing the unloaded side of a bump, or dropoff. Unfortunately, these do not have external rebound adjustment (the dealer I got them from is out of state, and they were not accurate in their description of the features). Grrr.

I’m quite sure the shocks are not bottoming, as they have substantial bumpers that would not allow such a violent "clunk". The rear shocks are not doing anything weird, but then, they are all bound up with a torsion bar.

Does anyone have experience with this and how to correct it, or am I a new inductee into the older-but-wiser (grab-your-ankles) club?
