Has anyone used after-market piston rings and if so what brand and where is the best place to look for them? I do not want to use anything that is junk and or will not last in a performance engine. I am running 50 psi in my 97' 3500 4X4. 0 plate, 64mm turbo, 370 injectors, 3k kit, ATS 3 piece, 4" exhaust and I am upgrading the cam to a 188-220.

 

I'm using malhe pistons I got them from peak diesel from Harry, they have been great I was ruining a single 66mm turbo but it got so hot I cracked the head and melted the volute out of the turbo different head and twins on it now but those pistons have taken a beating are still going strong much cheaper than stock and seem just as good.

 

thanks for the info.
