ZRP RODS – NISSAN RB26DETT PISTONS SET

NISSAN RB26DETT PISTONS ARE DESIGNED FOR MODERATE TO HIGH-PERFORMANCE TUNING, PRIMARILY FOR ROAD RACING OR CLUB RACING CARS LOOKING TO DEVELOP THEIR ENGINES FOR HIGH MILEAGE AND/OR STREET USE. DESIGNED BY ZRP ENGINEERS AND MANUFACTURED IN GERMANY FROM HIGH-SILICON, LOW-EXPANSION 4032 (T6) ALLOY. THIS ALLOWS THE ENGINE BUILDER TO USE A TIGHTER 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 HAVE 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.
