Is there a "performance related" reason everyone runs nitrogen shocks upside down? Ive been running mine upright both on the front and rear, but I notice nearly everyone runs them upside down.

I come from non-adjustable shocks on sprint cars where we ran them upright to keep moving weight to a minimum.... So I am a little curious if there is a reason to run the gas-filled shocks upside down or if its mainly to protect the shafts, etc. from rocks?

I'm old so the reasoning might be different today, when we first started inverting shocks we were trying to reduce unsprung weight

Oops, I just read the rest of your post. (see I told you I was old) so I have nothing, however it raises my curiosity also

I think what red's trying to say is that when we were kids, what you call "upside down" was "rightside up"...

It's because the shock adjusters are on the eye that is attached to the shaft (opposite end of the nitrogen bulb). If you mounted them with the shock "right side up" it would leave your shock adjuster cable going up and down with the axle, instead of stationary if they are mounted "upside down."

Ok that makes sense! We aren't allowed to run in car adjusters so that isn't an issue. I was more concerned on whether they needed to be upside down for the nitrogen to function where it needed to beproperly, or anything like that.

And a lot of guys just do it to make the numbers hard to read, I also do it to keep the unsprung weight down, if it makes that much difference, and as Studley says, with the adjuster cable being where it is, it do make a difference in how you mount them! Bob

Your all too old to be worried about which way to mount your shocks. Rocking chairs don't have shocks.

Jimmie, you got that right, but I can't help it, just wish I were up to it, I got enough tube here in the shop to build one more new car, but I don't know how long it would take, and I'm not sure if any of my Dr's would approve it, but what do they know, if I get my back, knee's and eyes, OK, my shoulders need some work too, but if that all magically comes together, I just might do it, NOT! Have a good day, Jim, maybe we'll see ya again someday! Bob
