ZRP Con Rod Kit Volvo B5254 143.00 Pin:23.00 I-Beam

The I-Beam Heavy Duty series Connecting rods are aimed for the High HP/Boost applications. Built from the finest raw materials 4340 high tensile steel with a specially optimised shape for high performance and extreme durability. These rods have a Tapered Pin End, so they are compatible with OEM pistons. The bushings are made from AMPCO 18 material for excellent resistance to wear and fatigue and have radial grooves for oil reservoir. They are shot peened to relieve stress from the material and multi-stage heat treated to increase rigidity. The tight tolerances in the production process ensures a perfect fitment while optimising the oil clearances. Bend and twist is tightly controlled. Each rod includes ARP 2000 cap fasteners that are rated at 220,000psi, ARP moly and full fitting instructions.

Additional machining processes

• Rifle Drilled for maximum lubrication to increase wrist pin longevity
• 'Straight Cut'Pin End - Suitable for aftermarket pistons.
• Dowel sleeves for perfect fit and accurate re-assembling
• Lipped Cap Relief for improved big-end integrity at extreme application
• Grooves in Thrust Face for weight reduction
