Don't know where you are but that looks like the older "K Bar S" or James duff suspension.
I don't think it is a lift though....you'd have to measure to be sure.
Having said that.,
I have the same front shock set-up. (mine works good, rides great, & articulates awsome) The forward-most front shocks are the add-ons., & I doubt they're available anymore. You can., however, put shock studs in the attach points & use a longer shock if you do a lift.
My upper shock mount had 2 extra holes drilled in them so I was able to lower the top mount position & just re-used those same shocks when I did my 2.5in. lift.
(dual shocks aren't really necessary.., but they don't hirt anything either)
The only reason I added a lift was @ my radius arm bushings blew out ...so while I had it appart I thought "what the hay" might as well do a small lift.
Sooooooooo..., You can do a lift now., later., or not at all....depending on your intended use..
HTH,
