when do i need to upgrade shocks?

i was thinkin about droppin my ride 2 inches... do i need to upgrade my shocks.. or can i ride the stock ones?... cuz on my Altima, i rode on stock shocks with a 2in drop

when lowering your vehicle that much, it is always a good idea to upgrade the shocks and struts as well. if by chance your spring rate is greater than your shock/strut rate, the shock/strut will bottom out, which is what causes the awful "rice hop"

u can used ur stock shock....but lower spring will blow ur shock sooner than stock spring...less life time with lower sping.....so u should change your stock shock to performance stock
