So... I was drooling over some pictures in the Post Your Pics thread, when I realized that some of the shock on some of the trucks are oriented differently than others. I know that some conversions and lifts, require special shocks, but in general, with stock replacement shocks or stock length ranchos, which end of the shock should be closer to the body and which should be closer to the road? I searched for a while, but couldn't find the answer, and am hoping someone can tell me whether it matters or not. Thanks.

 

Depends on the design of the shock. Some need to be can-down. others can be mounted either way. I know the Rancho 5000/9000 type shocks are designed for can down operation, since if the can is up, the shock valve at the end of the can may not be under the fluid level and damping will not be as solid. So the real answer is to check with the shock mfg. to see what they recommend.

 

In general most non gas-charged shocks should be installed can-down, and gas-charged shocks (for example RE monotubes) can be installed can-up if you want. As 4Crawler said it's best to check with the manufacturer. The benefit to can-up is that is slightly reduces your unsprung weight.
