just wondering if all TRW pistons are forged?thanks

No.

Actually I believe they are.
Under the new corparate name Federal Mogul, their cast pistons are made by Sealed power, their hypereutectics are made by Sterling, forged will be TRW (though they don't use that name any more)

Like rust said. They don't use the TRW brand name no more.

The forged ones are sold under the name Sealed power forged or power forged

The cast ones are sold under the Sealed power brand

And the hypers are sold under two brand names. Sealed power and Sterling
