Designed by ZRP engineers and manufactured in Germany from high-silicon, low-expansion 4032 (T6) alloy. This allows the engine builder to use a smaller piston to cylinder clearance, resulting in a better seal. This minimizes cold start knocking noise, common in engines using forged pistons, providing quiet operation and low oil consumption. We have chosen a full round skirt design with a reinforced lower band, with oversized and deeper valve pockets to allow for the use of high-lift camshaft profiles. They have offset pins for quiet operation and the piston pins are made of 9310 alloy. Other features include anti-detonation grooves to protect the top rings, a gas pressure accumulator groove for better ring sealing and vibration relief. Premium Japanese quality 1.00mm x 1.20mm x 2.80mm ring package included. Product Features and Design Anti-detonation grooves for extended life and performance Gas pressure accumulator groove in the second ring land for extended life. Horizontal pin bore grooves designed to allow oil to enter between the piston pin and the pin bore area.
