First up, a new set of Diamond Forged pistons, flat top, .020 oversize, 3.572 bore size, 10/28/16 production date. Got them yesterday and I ordered the wrong ones. I paid extra for the top ring gas porting for better ring sealing, speaking of rings these do not come with any because they want you to get the right type for your application, standard 1.5 top,1.5 middle and 3mm bottom size. These come with valve reliefs at .150 for the intake and .050 for the exhaust with extra material under the cuts for extra strength on the underside of the pistons which is pretty slick. Comes with 8 wrist pins at .866 diameter with Spirolox lock rings. The pins are offset .040 to keep the pistons from knocking from rocking. They are made from 2618 aluminum for high pressure use and weigh 366 grams each. These are unmolested, no scratches no mounting or sizing, fitting, measuring, brand new new in the box with all paperwork and production information. I paid 804.99 for them and will let them go for 700.00 Next up are a set of stock size cast hypereutectic flat top 3.552 bore with stock NPR rings. These are coated on the side and ceramic coated on the top and are stronger than stock with pins and circlips. These are unmolested too so no mounting or bore scratches I paid 260.00 for these and want 200.00 for them.
