ZRP RODS – PISTONS SET OPEL 2.0L 16V C20XE AND Z20LET

THE OPEL 2.0L 16V 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 CHOOSE A FULL-ROUND SKIRT DESIGN WITH A LOWER REINFORCING BAND, WITH OVERSIZED AND DEEPER VALVE POCKETS TO ALLOW THE USE OF HIGH-LIFT CAMSHAFT PROFILES. THEY FEATURE OFFSET PINS FOR QUIET OPERATION, AND THE WRIST PINS ARE MADE OF 9310 ALLOY. OTHER FEATURES INCLUDE ANTI-DETONATION GROOVES TO PROTECT THE FIRST RINGS, A GAS PRESSURE ACCUMULATOR GROOVE FOR IMPROVED RING SEALING AND VIBRATION REDUCTION.
