Carrillo BMW/Toyota B58 - CC 5.828in Pro-H 3/8 WMC Bolt Connecting Rods - Set of 6

CP-Carrillo pistons and connecting rods are manufactured to motorsport tolerances and built for high-power, high-RPM applications. Each component is custom-machined to order, making Carrillo parts a preferred choice for professional engine builders, drag racers, and road racing teams worldwide. Popular Upgrades The most popular Carrillo parts include custom forged connecting rods in H-beam and I-beam configurations for high-boost and high-RPM builds, custom forged pistons with precise compression height tolerances, and matched piston-and-rod sets for complete rotating assembly upgrades on turbocharged, supercharged, and naturally aspirated engines. What makes Carrillo connecting rods different? Carrillo rods are made from aerospace-grade steel or billet aluminum and manufactured with tighter tolerances than most production rods. They are rated for significantly higher RPM and load cycles than OEM components, which makes them a standard choice for builds pushing 600 horsepower and be...

Performance connecting rods are a foundational upgrade for any engine build that will push beyond factory power limits. OEM connecting rods are designed for stock power levels and cast iron construction that may not handle the combination of high RPM, forced induction, and increased cylinder pressure present in a serious performance build. H-beam and I-beam forged steel rods provide the tensile strength and fatigue resistance needed to survive those conditions reliably.Popular UpgradesH-beam connecting rods forged from 4340 chromoly steel are the most popular choice for turbo and supercharged street builds targeting 500 to 1,000 horsepower. I-beam rods are preferred in applications where compressive loads exceed tensile loads, such as naturally aspirated high-RPM engines and certain diesel applications. Lightweight titanium rods are used in maximum-effort race engines where rotating mass reduction at extreme RPM is the priority.What is the difference between H-beam and I-beam connec...

Connecting rods and push rods are critical internal engine components that transmit force within the combustion cycle. Connecting rods link the piston to the crankshaft, while push rods in overhead-valve engines transfer cam lobe motion upward to the rocker arms and valves. Upgrading both types with forged steel or chromoly alloy components increases durability and allows an engine to handle sustained high-RPM or high-boost operation.Popular UpgradesForged 4340 chromoly H-beam connecting rods are the standard upgrade for any performance engine build targeting more than 400 horsepower, replacing the cast or powdered-metal OEM rods that cannot survive the fatigue cycles of performance use. Performance push rods in hardened chromoly with specific wall thickness and length specifications are essential for LS and small-block Chevy builds where custom camshafts alter valve train geometry. Matched sets in the correct length and diameter simplify assembly and ensure consistent valve train g...

Six-cylinder connecting rods cover inline-six and V6 engine platforms used in a wide range of performance vehicles, from the Toyota 2JZ and BMW S54 to the Nissan RB26 and GM's LY7 and LFX V6 engines. These engines are frequently pushed far beyond stock power levels with forced induction, requiring connecting rods that can survive the increased tensile loads without fatigue failure.Popular UpgradesH-beam 4340 chromoly connecting rods for the Toyota 2JZ-GTE, BMW S54 and S55, Nissan RB25 and RB26, and various Chrysler and GM V6 platforms are the most popular six-cylinder rod upgrades. The 2JZ in particular has an extensive aftermarket rod catalog, supporting builds well past 1,000 horsepower on the factory block when paired with quality rods and pistons. I-beam rods with ARP bolts are used in naturally aspirated high-RPM race builds where lightweight construction and compressive strength are the primary concerns.What rod bolts should I use with aftermarket six-cylinder rods?ARP 2000 or...

This engine parts collection covers oil catch cans, thermostats, thermostat housings, radiator components, coolant accessories, engine covers, fuse box covers, cap covers, throttle bodies, supercharger pulleys, idler pulleys, tensioner pulleys, and engine bay dress-up parts for trucks, SUVs, muscle cars, boosted builds, high-horsepower street cars, and performance vehicles that need better reliability, cooling, airflow, oil control, and under-hood styling. The collection is particularly strong for Dodge Challenger, Charger, Durango, Jeep Grand Cherokee Trackhawk, and Ram TRX platforms running 6.2L Hellcat, 6.4L HEMI, and 5.7L HEMI engines, where oil catch can and cooling upgrades address known OEM weaknesses in the PCV and thermal management systems. Import performance platforms including GM LS-based builds, Chevrolet Camaro, and Corvette applications are also represented through Mishimoto, CSF, and ZPE GripTec product lines. Builders who invest in engine bay organization and reliab...
