just that they don't say anything aboutthem being reinforced.

I think I'm going to sprng for the rering kit which includes all the bearings for $133.

Stock TGP pistons arent anything special, they just have an extra ring on them

IIRC the stock TGP pistons (MAHLE) not only have an extra ring. They also have larger pin bosses, a skirt below the wrist pin, a 2" oil return, and seem to be built a little tougher overall. :D

Mahle pistons don't have an extra ring. There a standard 3 ring piston. The 4th ring myth is not a ring at all, its a band. It doesen't even go all the way around the piston. Picture it as 2 segments of a thick hose clamp cast in the inside of the piston skirt.

 

Here's the difference.

 

Mahle / TRW

Skirt below the wrist pin. Yes / no.

Steel band cast in skirt between and into pin bosses. yes / no

Huge pin bosses. Yes / no.

Oil return per side. 2’’ / 1’’.

Weight 494-496 g / ? felt lighter.

Appearance Stout / like for a toy.

Cost 98 / 120-130

 

 

Don’t know that the TRW pistons wouldn’t be fine. That’s the problem, just don’t know. I decided not to use them.
