Nissan GTR VR38 DETT I-Beam Heavy Duty Connecting Rods

The I-Beam "Heavy Duty" series connecting rods are engineered for high horsepower and boost applications. Constructed from 4340 high tensile steel, these rods feature a specially optimized shape for enhanced performance and durability. The "straight cut" pin end increases durability, designed for use with aftermarket pistons. Bushings made from AMPCO 18 material provide excellent resistance to wear and fatigue, with a radial groove acting as an oil reservoir. Shot peened to relieve stress and multi-stage heat treated for increased rigidity, these rods ensure a perfect fitment with optimized oil clearances. Bend and twist are tightly controlled.

Technical Features

• I-Beam shape for extra rigidity.
• Two-piece forging for great strength.
• Shot peening for improved fatigue life.
• Magnaflux inspection ensures material consistency.
• Double ribbed caps for added support.
• Multi-stage heat treatment for maximum strength and dimensional stability.
• CNC machining for superior tolerances, precise to 0.0002".
• Center to center maintained under 0.001" tolerance.
• Finite Element Analysis (FEA) for stress analysis.
• Optimal balancing for weight matched sets of ± 1 gram.

Additional Machining Processes

• "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 in extreme applications.
• Grooves in thrust face for weight reduction.

Each rod includes 3/8 ARP 2000 cap fasteners rated at 220,000 psi, with an optional upgrade to ARP L19 material rated at 260,000 psi. The kit is supplied with ARP moly and full fitting instructions.
