Anybody knows where to get a 8/32 tapper? Haven't seen in hobby shops and as I'm living in the metric part of the world, the hardware stores are not stocking them as well.

DB3060 does work fine on the DB12RR. It will require longer ballcups but it works great. Let me see if i can repeat this problem and come up with a solution. I havent had any problems with mine so far. I will let you know what i can find.

Is the DB3060 a better shock by design? Do you recomend it over the Silva shock? Do you have a part number on those longer ball cups you mentioned? Just by looking at the DB3060 and the Silva, the DB3060 looks like a better shock. Thanks

I made a typo in my previous post. Part# DB3060 IS the Silva shock. I meant to ask if the shock which is part# DB3150 will fit on the DB12RR. Sorry. Just wanted to make sure I clarified what I was asking, Thanks.

DB3150 is a larger 1/10th macro shock. It will not work on the 1/12th. I will see what i can find on the 1/12th shock before you give up on it. It really is an awesome shock.

I was told to try the Hot Bodies 1/12th scale shock, but I heard it was the same shock as the Silva.

They are about the same. I am going to be looking into making some optional pistons for the silva shock. Try running 60 wt oil in the shock. I ran 35 wt when i 1st got it and it seemed to develope some air bubbles. With the piston having holes in it, it makes the shock need alot heavier oil to have the same feel as an IRS of VSC shock.

I have been running Losi 45 weight in it. Should I still go to 60 weight? How musc is going from 45 to 60 weight going to effect the handling? Is it possible that I have a faulty shock?

There isnt much that can be fault on the shock. If you install the shock shaft with a dry Oring you can damage the Oring but thats the only part that can leak.

45 wt. is going to be too light for most conditions. 50-60 wt. is going to be around 30-35 in the IRS shock. 45 is going to be more like 20-25 wt.
