JRspec Forged Connecting Rods for R32/R33/R34

Introducing a set of high-performance forged connecting rods by JRspec, designed specifically for R32, R33, and R34 models. These rods are crafted using advanced H-beam technology and are compatible with 2.5L GTS L6, 2.6L GTR 260RS, RB25, RB25DET, RB26, RB26DE, RB26DETT, RB28, and RB28DET engines.

Constructed from premium forged steel ANSI4340 (EN24), these rods offer exceptional strength, supporting over 200 HP per cylinder. The manufacturing process includes vacuum degassing and x-ray inspection of all forgings before processing. Each rod undergoes heat treatment and normalization, followed by stress-relief to ensure durability and performance.

Precision is key, with each hole honed twice to guarantee a perfect circle with a tolerance of 0.01 mm. The rods maintain vertical straightness to 0.01 mm, significantly reducing bearing wear compared to many branded alternatives. Every kit includes a connecting rod and end with a unique individual number, packed and balanced by weight end to end.

The heads are reinforced with high-quality bronze sleeves in the rear piston pin position, ensuring maximum strength. These connecting rods have been rigorously tested in a 1,500 HP Calibra Tsunami, proving their reliability and performance under extreme conditions.
