The OP has a 2001 2nd Generation 4x4. There are no torsion bars.....
He does have coil spring and shock with 4 link front suspension.
Yes, a coil spacer is a cost effective list option. Take a look around as there are many offerings. For a year I ran 2.5" ones from Hell Bent Steel. If you have stock block in the rear, then I'd suggest only 2". This is so you don't get too nose high. I had other stuff on mine since I have an offroad edition ram.
No need to change shocks either.
