They should have come with new Big Bore shocks. I imagine any nylon bushing with the proper ID would work though...
They are listed separate as well:

I'm using the springs on mine with white long springs instead of the softer ones it came with. They are about as stiff as the short ones.

Pretty sure I have a few sets of the tubes around... no clue where though. When I got my flux hp, it had RPM arms on it and they would twist so much on hard landings that it would snap the shock end off. The only way to get the shock ends was to buy that $16 parts tree. I spent $32 to have spares... after I busted my 4th one, I bought a full set of stock arms and ditched the RPM arms. No busted shock ends since.

Are you going to use a 4 shock setup or 8? When I had RPM arms on mine with 4 shock setup, I kept snapping the shock ends off on the front shocks whenever I landed funny or big jumps. The arms twist/flex too much and snap them in half repeatedly. I'm assuming an 8 shock setup would help put the load on both sides of the arms and help with the issue.
