So I put on the Fox racing shocks back during the summer.  After a couple of months I noticed the rear passenger side sitting lower.  I measured from center of hub to bottom of fender: drivers side rear = 26"; passenger side rear = 24.5".  The next time I was at the dealer I had them check it and they see the Fox shocks and immediately blame it on them.  I shake my head and leave, planning to swap the stock shocks back on and drive back to them (an hour away) to have them finally find the problem.  Well, I just got done swapping them and to my surprise it was the shocks.  When I measure it with the stock shocks on I get about 25.5" on both sides.  So, the dealers off the hook. 

Now, how do I fix the shocks?  There is a valve on them where I assume you can adjust the pressure.  But what goes in there and what pressure am I looking for?  I got them from Samco and I sent him an email last weekend but he has not replied yet.  Any thoughts?

Can anyone else measure their stock Adventure setup and tell me what they have?  And I also compared the overall legnths of the rear stock shocks and the Fox shocks.  They are identical, 24" from the center of bolt hole at the bottom to the centerline of the mounting spot at the top.

One of the fox shocks may have more pressure than the other.    I was looking around at rebuild instructions for the fox stuff and found most of their shocks are run at 200 psi of nitrogen.   I couldn't find the specs for those exact ones but for the most part they were at 200 psi.  Dont use air.  This is important.   Nitrogen is inert, and dry with no contaminants and is unaffected by temperature changes.  It will help keep the oil in the shock from foaming causing fade.   Im trying to find a way to reduce the size of the internal stopper in the fox shocks to allow for more travel but i cant find internal pictures or diagrams.

Nitrogen, right.  Any special way to measure the pressure?  Or just a normal pressure gauge that can get up over 200psi?  Do tire gauges go that high?

I have always used the regulator on the nitrogen bottle set it at about 210(the extra is compensate for the loss you get when removing the the air chuck)   Then just put the air chuck on the valve and remove. The whole process of filling or removing the nitrogen is extremely fast due to the very small quantity of nitrogen in the shock.  This also makes it almost impossible to check because even the act of putting a gauge on it changes the amount drastically. after doing this you can check the trucks level.  My truck measures: lft rr = 24.5 "  rt rr = 24.25"  with the adventure package
