what am i supposed to belive here!!

ok i bought the hb alum shocks . i have heard all over this stinkin web differnt stories about shock weight oil i have heard from 15 to 65 weight oil in these things what is a good oil . I put 40w in and a little bouncy on rough dirt it falls over, dont know if holes in pistons are not good enough for that heavy of oil or not. also does not seem to rebound far enough. what should i try in theese things? also where am i gonna get rebuild kits for these?

The oil weight you need will be determined by your desired effect. The shock cylinder acts as a dampener to the spring. If you use a light weight oil, the shock will move faster but the spring will do most if not all of the work. If you use a heavy weight oil, the shock will react slowly and the cylinder will do most of the work.

I run 60 wt oil in my HB threaded aluminum shocks.

As far as rebound height, that will be determined by the springs you use and the pre-load spacers you use. More spacers means more pre-load and that should translate to more rebound height. If the springs suck, then you have to get better springs.

As for your observation that it was "bouncy", that means you used too light an oil and the springs were doing the work.

As for rebuild kits, contact Hot Bodies or ask at your LHS. Mine gave me a 1/10 scale shock rebuild kit when I asked for one.

do you use the springs that came with the hot bodies shocks and also is the 60 wt oil allow the a arms to move over stuff and not rock the truck from side to side?

I use the springs that came with the shocks, and I get good articulation from all corners. The A-arms have a good range of travel and move throughout that range smoothly. As for "rocking", I have not seen that out of my truck. The suspension is just right for my truck...which means not stiff enough to produce the "rocking" you describe.

question again when filling them is it true you want them to spring back when compressed about a half in? that is what the lhs stated for propper bleeding but i read different here and there
also maybe i forgot how this thing sat stock it just seems to rebound slowly and not very far when i push the truck down by hand

Proper bleeding of shocks can be a problem. If you do not bleed them correctly, you end up with an over full shock cylinder which causes them to not work correctly.

First fill the cylinder most of the way. Then you want to pump the cyclinder a couple of times to remove the air. Once you are fairly certain that you have all the air out. Fill the cylinder the rest of the way (right up to the top edge of the cylinder). Then slowly push the plunger up until you see the oil start to bulge out the top of the cylinder without spilling out. Then you want to put the cap on it and tighten it down. Clean it up, whiping any excess oil (and there will be some that spills as you put the cap on and tighten it down).

From there you can test the cylinder by compressing it all the way. It should rebound about 1/2-3/4 of an inch. This means things are good. If you compress it half way and get this kind of rebound, you have over filled the cylinder and can expect to rebuild it real soon after the first time you drive it hard.
