I had an 94 S10.... and lowered it  3inches in front and rear............and then raised it back up.......... you will need the stock size coils and (possibly...front spindles)..depending on what lowering componets  that were used ~ .... and stock sized shocks....in the front and in the rear... you would need........ stock size shocks...... and stock length... u Bolts........... ~

 Good Luck on Raising your S10 back to stock ride height!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
