Shock Inversion

The only benefit is if you need to clear a suspension component.

Gas shocks don't care what position they are in: even horizontal, as in the steering stabilizor.

Most shocks can run inverted. Racers do this to decrease unsprung weight (every pound counts on a race vehicle). Others do it for clearance, some for looks. Do not invert a Black Diamond XT shock (trust me on this) they don't work.
