Whats the difference between the regular 1500 ls and the 1500 HD? is the suspension difference just springs and coils or is the front a completely different sub and crossmember? I am thinking about putting the hd stuff on my regular 1500

The 1500 HD has the 2500 Suspension & brakes.

if I wanted to do the swap is it as easly as just changin springs and leafs etc or is it a completely different crossmember assbly and steering etc.

1500hd also has the 14 bolt and the 4l80e trans behind the 6.0L
