Carrillo SCR4890-1 Pro-SA Connecting Rod Nissan VG30 VG33 6.070in 3/8 WMC

The Carrillo SCR4890-1 is a single Pro-Super A (Pro-SA) beam connecting rod engineered for the Nissan/Infiniti/Datsun VG30 and VG33 engine family. Featuring a 6.070-inch center-to-center length, a 22mm full-floating wrist pin bushing, and a 3/8 WMC (H11 tool steel) rod bolt, this rod is purpose-built for high-horsepower, high-boost, and high-RPM applications.

The Pro-SA beam design bridges the gap between Carrillo's Pro-H and standard Pro-A configurations. With an increased beam thickness over the Pro-A, it delivers a higher load capacity while remaining lighter than a traditional H-beam rod — making it an ideal choice for turbocharged and supercharged builds where both strength and reduced reciprocating mass are critical.

Key Features:

• Pro-Super A (SA) Beam Design — increased beam thickness for higher load capacity vs. standard Pro-A, lighter than Pro-H for reduced windage
• 6.070" Center-to-Center Length — correct OEM replacement length for VG30/VG33 applications
• 22mm Full-Floating Wrist Pin — bronze bushed small end for superior wrist pin lubrication and longevity
• 3/8 WMC Rod Bolt (H11 Tool Steel) — 220,000 PSI ultimate tensile strength fastener for reliable clamping force at extreme RPM
• Advertised Weight: ~534g — lightweight design for reduced rotating assembly mass
• Carrilloy Proprietary Steel — chrome, nickel, moly, vanadium alloy meeting VAR (vacuum arc re-melt) ASTM standards
• USA Manufactured — forged and machined at Carrillo's Irvine, California facility
• 100% Magnaflux Inspected — each rod is magnaflux tested twice and Rockwell hardness tested during production
• Shot Peened Finish — enhances surface compressive stress for maximum fatigue resistance
• Spec Card Included — every rod ships with a specification card listing part number, critical dimensions, weight, and job number for traceability

Each Carrillo connecting rod is manufactured from oversized proprietary steel forgings to ensure proper grain flow and eliminate surface inclusions. The result is a consistently balanced, race-proven rod trusted by professional engine builders worldwide. Sold individually (1 rod).
