Carrillo SCR4236-6 Toyota/Lexus 2JZ Heavy Duty Pro-H Connecting Rods

Designed for high-horsepower and racing applications, these H-beam rods are built to deliver exceptional strength, precision, and long-term reliability under extreme loads.

Each rod is fastened with 3/8" CARR Bolts — a significant upgrade over the ARP2000 bolts commonly found in competing rods. The proprietary Carrillo bolt design is engineered to maintain clamping force and integrity under severe rpm and boost conditions.

Key Features:

• Heavy Duty Pro-H beam design — rated for up to 1,800 hp in the 2JZ platform
• Proprietary alloy steel — chrome, nickel, moly, vanadium composition meets all VAR (Vacuum Arc Re-Melt) ASTM standards
• Mar-aged heat treatment — delivers an Ultimate Tensile Strength (UTS) of 195,000 PSI with a yield of 182,000 PSI while maintaining critical low notch-sensitivity and ductility
• Oversized forging process — ensures proper grain flow and removes surface inclusions or conversions generated during forging
• 3/8" CARR Bolt hardware included — premium proprietary fasteners superior to standard ARP2000 bolts
• Pin oiling holes at 10 o'clock and 2 o'clock — optimized placement for high-power applications
• CNC machined with probing validation — all critical dimensions are verified at the machine center for consistent precision

Carrillo connecting rods are manufactured under rigorous quality control standards, with material validation performed by both the steel supplier and an independent metallurgist confirming all physical and chemical properties. CP-Carrillo holds ISO 9001 certification, reflecting their commitment to consistent manufacturing excellence.
