Carrillo SCR5518-4 Pro-H Beam Connecting Rods Toyota 2ZZ-GE Lotus Elise Exige

Designed for high-power forced induction builds, these rods are rated to handle 1,000+ horsepower while maintaining precision tolerances straight out of the box.

Key Features:

• Pro-H Beam design — Carrillo's strongest rod configuration, engineered to withstand extreme cylinder pressures and high RPM
• 5.433" rod length — direct replacement center-to-center measurement for the 2ZZ-GE application
• 20mm wrist pin bore — bushed, full-floating configuration for reduced friction and maximum durability
• 3/8 CARR proprietary rod bolt — Carrillo's highest-grade fastener, included with each rod
• ~453g advertised weight per rod — optimized mass for high-revving applications
• Carrilloy steel alloy — a proprietary chrome, nickel, moly, vanadium alloy meeting all VAR (vacuum arc re-melt) ASTM standards
• UTS of 195,000 / Yield of 182,000 — achieved via mar-aged heat treat process while maintaining low notch-sensitivity and ductility

Every Carrillo rod is manufactured in the USA from oversized proprietary steel forgings to ensure correct grain flow and eliminate surface inclusions. Each piece is magnafluxed at least twice during production and Rockwell tested to validate the heat treat process. CNC machines equipped with probing verify dimensional integrity at every critical step.

Small End Note: All 2ZZ-GE aftermarket connecting rods feature a wider-than-stock small end for maximum durability. This is fully compatible with all aftermarket 2ZZ pistons. Use with OEM pistons requires slight machining of the piston pin boss for clearance. Old manufacturer part number: TO-2ZZGE-65433S-04.
