These ZRP H-shaped forged connecting rods, designed for your Nissan RB28 engine, are intended for engine tuning projects based on the Nissan RB26. With their specific length of 119.50 mm, they provide a suitable solution for creating a reinforced moving assembly for tuned and heavily loaded engines.
Manufactured from high-strength 4340 steel, these ZRP connecting rods undergo a multi-stage heat treatment and shot peening to enhance their fatigue resistance. Their H-shaped design combines mechanical strength with weight optimization to withstand the stresses encountered in high-performance engine builds.
Each set includes 6 matched connecting rods with a weight tolerance specified by ZRP of ±1 g. The connecting rods are equipped with ARP2000 fasteners, and ZRP also offers an upgrade to ARP L19 fasteners for engines subjected to particularly high engine revs or supercharging levels.
The manufacturing process includes precision CNC machining, connecting rod small ends with radial grooves that serve as oil reservoirs, centering rings to ensure precise repositioning of the connecting rod cap, and Magnaflux testing of the forged connecting rods.
