Question Shocks, upside down

Can anyone tell me if there is any benefit to mounting shocks upside down, or rather with the shaft side mounted to the axle. If no benefit, what's the difference?

When they fill up with water you will know the difference.

and you leave the shaft lower so your more likely to bend it or break it. Not worth it, and I cant think of any pro's.

It only works on motorcycles (and maybe, McPherson strut systems?) to reduce the unsprung weight.

Also some shocks are valved differently for compression and rebound.

On lots of race cars they are mounted upside down to reduce unsprung weight and also to make more clearance.

Thanks for correcting me... I was thinking of the entire shock like it was a suspension element when one end is actually fixed.

Thanks, I was thinking about mounting one of my duals upside down if there was a benefit.

Check with the manufacturer of your shocks. They will tell you if there is a benefit or not.

If you have a relatively light suspension (unsprung mass) in comparison to the weight of the shock body (back to the race cars and motorcycles and stuff like Ferrari) AND race AND need that last 1/10 in the lap, do it. (This is NOT the description of ANY truck I know!) It won't change the response of the shock. There are seperate internal valves for rebound and compression. The best shocks are the first place to start. Koni is the only MFG, I know of, that has both adjustable. I don't know if they even make them for trucks, they are really expensive. Rancho lets you adjust just compression with the RS-9000. Are you just musing, 351, or unhappy with what you have now?

Guys, let's not forget that most shock absorbers are specifically valved for compression and rebound and not normally 50/50. So if you want to muck with the orientation of your shocks you have to purchase ones specifically valved for the orientation you desire.

Had to jump in on this one.

But by the time I got back to finishing this one Ecuri nailed it on the head.

Upside down or right side up, compression is still compression, rebound is still rebound.
Some shocks aren't made to be used upside down though so that has to be checked into before just flipping your shocks over.

I had thought that some F-150s and Broncos came with the front shock (of dual option) mounted upside down. From the factory, that is. It would seem that mounting them upside down would make the shaft prone to bending(in a 4x4). Thanks for all the help, I was just curious. Always expanding my knowledge.
