I've heard that if you get a aftermarket valve such as the Rat or Tornado it is recommended that you get an aftermarket hammer. Can anyone shed any light on this?
I dont think you HAVE to use an aftermarket hammer. But if you are building a custom cocker why not just drop in a hammer kit anyway. AKALMP makes a hammer kit if you have the tornado. It will work with the rat too though. I think a hammer kit is a good idea becuz it gets maximum performance out of the valve.
Yeah, Belsales stuff is sold by SP in the US. A shocktech or AKA hammer kit would do nicely as well. As far as valves, I've heard nice things about the Rocket valve by Maddmann, and want to try the RED valve if I get the chance.
