Is anybody out there running their front shocks upside down?

Do they feel that they work well that way?

I am interested if you noticed any difference from the correct, as built, direction.

I would think they would NOT work as good as the right way .Its not like a motorcycle fork that is inverted they are made to work that way.

What flipping your shocks does is it lightens your "unsprung" weight by bolting the heavier body side to the frame, and the lighter shaft side to the suspesion. The shock itself will still react the same way, compression is still compression and rebound is still rebound. Unless you are a serious racer that has gone to every extreme to lighten your unspring weight, you won't notice any difference. Also I wouldn't recomend flipping any shocks that are not gas shocks, as they tend to begin leaking around the shaft seal much sooner than normal. I don't think the front Raptor shocks are gas charged.

EDD your point is exactly correct. The action is too fast.

I put my shock on a shock dyno in both configurations and they were completely different.

Basically upside down they lost almost all the compression damping and the rebound damping had a huge delay. I think they start sucking air when they are upside down.

I will try to post the shock dyno data but I don't have a website. I can scan the data and send it to somebody if they want to post it. It is really interesting.

My recommendation is not to run them upside down.

i hit a little 15 foot double on my raptor with my shocks flipped, I wouldnt advise anyone to flip them, I'm lucky my frame didnt take a dump on me, or a shock bust, I got lucky, cuz as soon as my tires thought about hitting the ground they were bottomed out. and it wheelied when it sprung back up and almost flipped back.

fipped the springs and nearly flipped myself. bad idea. it made the front end feel like an old shoe. the steering was stiffer and really made me tired. bottomed out like they were blown out. ruined a day of riding.
