A friend of mine has a BII and we found a 4in trailmaster lift for it used. My question is what else will we need that it don't come with?

It comes with:
4" coil springs
drop brackets
drop pitman arm
set of explorer leafs
add-a-leafs

I think all we would need would be new bolts (because most of his broke when taking it off) shocks, and extended brake lines. Speaking of which where would be the cheapest place to get shocks and brake lines?
