if i were you I would go with the Rocky-Road lift
well from what i know the 2" spacer Revtek Lift does not come with shocks nor does not require that you replace them. you can get it for about $270.00. the Rocky-Road 2.25 Lift also does not require shocks but they do sell a package with replacement shocks for $296.00.
if i were you I would go with the Rocky-Road lift. it is a better ride and it comes with shocks, it is a easy spacer install if you have the right tools for the job "spring compresser" lol for 30 bucks more its worth it
Do you have QT1??
or you could just buy the 4" super lift it comes with shocks but that a bit of a price tag and a bit harder to install lol
