Carrillo SC7116X-4 Pro-SA Super A-Beam Connecting Rod

Key Features:

• Super A-Beam design — increased beam thickness over standard A-beam for higher load capacity, reduced reciprocating mass compared to H-beam rods
• Proprietary Carrilloy steel — chrome, nickel, moly, vanadium alloy (4330M) meeting VAR (vacuum arc re-melt) ASTM standards, validated by independent metallurgists
• Oversized forging process — ensures proper grain flow and removal of surface inclusions generated during forging
• Multi-stage quality inspection — each rod is magnafluxed twice and Rockwell hardness tested to validate heat treatment; laser-serialized for full traceability
• Shot-peen finished — controlled shot peen operation relieves tensile stress and improves fatigue life
• Precision CNC machined — all critical dimensions validated with in-machine probing for tight tolerances
• WMC cap screw fasteners — H-11 tool steel bolts with 220,000 PSI UTS and patented asymmetric thread design for maximum clamp load and fatigue resistance
• Made in the USA

Carrillo Pro-SA rods are well-suited for forced-induction builds including turbocharged, supercharged, and nitrous applications where cylinder pressures exceed the limits of standard A-beam rods. Built to the same stringent tolerances as the Pro-H line, the SC7116X-4 delivers race-proven strength and durability for high-revving performance engines.
