How would I go about lifting a 1992 Falcon about 2 inches? What products should I use and would I find any problems when doing so.

what chasis? sedan, ute or wagon (as the suspension is different).
are you lifting it from stock?
King Springs do raised springs both leaf and coil.
I suppose you'd need longer shockabsorbers to but.

It is an EB, sedan, falcon. Doing it from stock, just do alot of gravel and dirt driving.

Get raised King Springs then (you can find the part number on there website).
Monroe GT Gas (35-0191) for the front and either GT Gas (15-0202) for the rear or get there Gas-Riser Shock Absorber (MGR-109) (pump up air suspension).
Hope that helps.
