Force pistons?

[jason32038]

I've been meaning to ask this for a while but always forgot. What material are force pistons made out of? They seem ultra light weight and weaker than auto pistons. I have an 85hp.

Standard pistons are cast aluminum alloy. You can also get forged aluminum alloy aftermarket ones which are more rugged.
