ZRP RODS – PISTONS SET OPEL 1.6L Z16LER / LET

The Opel 1.6L Z16LET pistons are designed for moderate to high-performance tuning, primarily for road racing or club cars looking to develop their engines for high mileage and/or street use. Designed by ZRP engineers and manufactured in Germany from a high-silicon, low-expansion 4032 (T6) alloy. This allows the engine builder to use a closer piston-bore clearance, resulting in better sealing. This minimizes the slapping noise during cold starts, common among engines using forged pistons, ensuring quiet operation and low oil consumption.
We chose a full round-skirt design with a lower reinforcing band, with offset pins for quiet operation, and the wrist pins are made of 9310 alloy. Other features include anti-knock grooves to protect the first rings, and a gas pressure accumulator groove for improved ring sealing and vibration reduction. Includes a pack of premium Japanese-quality 1.00 mm x 1.20 mm x 2.80 mm rings.Product Features and DesignAnti-knock grooves for long life and high performanceGas pressure accumulator groove in the second ring for increased wear resistance.Horizontal slots in the pin bore designed to allow oil to penetrate between the pin and the pin bore area.Precision CNC machined ring groovesHigh-silicon/low-expansion 4032-T6 alloyHoned pin boresFull-round skirt with lower reinforcement band for high HP/boost applicationsPistons designed to optimize squish for longer engine life and increased power potentialOptional coatings offered on requiredBlast Off Bronze Thermal Barrier CoatingStealth Black Side-Skirt and Under-Crown Moly CoatingAdditional InformationApplication1.6L Turbo Z16LET (Corsa OPC), 1.6L Z16/A16Bore Size79.00mm, 79.50mmWeight Gr.276, 282Stroke 81.50mmOffset Ratio8.5:1OEM Offset Ratio8.8:1Height Comp. 28.00mmAction 129.75 mmPin diameter 19.00 mmClearing the bridge 0CCS Dome -5.0CC, -5.6CCSet of rings 21-GNH7900, 21-GNH7950Wrist Pin Pn WP019
