GM Quad shocks?

[WhiteBurb]

I'm getting ready to lift the truck 4" and have a question I couldn't find the answer to on a search.
My truck already has dual shocks on each front wheel from the factory. Which shock position is considered the primary and which is the auxillary? I'm switching to single and just want to make sure I put it in the right spot, or will it really matter?

Thanks.

The shorter length, or the forward mounted one is the primary.

If I were you, along with others who would agree with me, I would use the longer mounted, rearward position shock so you can have a longer travel shock instead.

Thanks. I got the longer one for the rear. Its only temporary anyways, until I get enough $$ for some MX6R or 5150's attached to Ford mounts.
