Carrillo CR12535-8 PRO-H Connecting Rod Set GM LS XD 8-Cylinder

Designed for serious forced-induction and high-revving builds, these rods are built to withstand the punishment of boosted race environments where stock or budget rods simply fail.

Key Features:

• PRO-H H-beam design — optimized beam profile for superior strength-to-weight ratio under high cylinder pressures
• Proprietary Carrilloy steel — a chrome, nickel, moly, vanadium alloy meeting all VAR (vacuum arc re-melt) ASTM standards for maximum fatigue resistance
• CARR bolt fasteners — CP-Carrillo's high-strength rod bolts featuring asymmetrical threads for even thread engagement, increased clamp load, and improved fatigue life; rated for high-RPM use
• 2.100" rod journal — engineered for GM LS XD crankshaft journals
• 0.927" bushed floating wrist pin — precision small end bushing for full-floating pin operation
• Multi-step inspection process — each rod is magnafluxed twice and Rockwell hardness tested to validate heat treat; laser-engraved job number for 100% traceability
• Shot-peened finish — controlled shot peen operation introduces compressive surface stresses to maximize fatigue life
• Made in the USA — manufactured at CP-Carrillo's precision facility in Irvine, California

CP-Carrillo connecting rods are the benchmark for performance engine builders. Carrilloy steel forgings are manufactured from oversized billets to ensure proper grain flow and eliminate surface inclusions, delivering consistent strength and reliability from street performance to all-out competition use. Each set includes CP-Carrillo's moly-based fastener lubrication for proper installation.
