An economical price but without compromising quality and performance. The shape is optimized depending on the model, some come in H-shape and others in I-shape. Depending on the application, turbo or naturally aspirated, the design is customized for weight and rigidity.

HEAVY DUTY Series Forged Connecting Rods:

Built from the finest raw materials with a specially optimized shape and fits 3/8" L19 bolts in all applications. The design of these connecting rods has been developed for each application individually in order to optimize the design based on each engine.

PRO SERIES 817M40T - EN24T ALLOY

Built from the finest raw materials with a specially optimized shape fits 3/8" L19 bolts in all applications. 817M40T steel is a steel with a hardness that is in the 248/302 HB range. 817M40T - EN24T can be further surface hardened to create components with increased wear resistance by induction or nitriding process.

Forged Crankshafts:

ZRP crankshafts are manufactured from 4340 steel. The crankshaft production process involves very detailed inspections to ensure they have the best quality and tolerances for a perfect fit.

• Multi-stage heat treatment.
• ION (plasma) nitriding for hardening.
• Heat treatment for superior wear resistance.
• Magna flux for a flawless surface finish.
• Shot peening for stress relief.
• Micro-polishing for longer bearing life.
• Finally, they are subjected to sound and X-ray testing to ensure a reliable final product
