I have a 91 toyota pickup 2WD, and I wanted to put a 4" superlift, but I was wondering if I could since I only have a 2wd and not 4wd

the one I wanted to get is here: http://www.summitracing.com/catalogs/bigbook/2004/janfeb/310f.html

its the SLF-K307 1989-96 pickup 4-5" lift

I am pretty new to fixing up my truck and getting into lifts so I am not quite sure what to look for and get to lift it up 4". Any help would be appreciated.
