Eagle Chevrolet 305/350 Press-Fit I-Beam Connecting Rod Set (Set of 8)

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...

Eight-cylinder connecting rods serve the most popular domestic V8 platforms in the performance aftermarket, including GM's LS and LT families, Ford's Coyote and Boss 302, Chrysler's Hemi, and the classic small-block Chevy and small-block Ford families. Upgrading connecting rods is essential in any V8 build targeting sustained power output beyond what OEM powdered-metal rods can survive.Popular UpgradesH-beam 4340 connecting rod sets for the GM LS1 through LS9 family and LT1 and LT4 are the most popular V8 rod upgrades, supporting builds from 500 horsepower street cars to 2,000-plus horsepower drag cars. Forged small-block Chevy and small-block Ford rod sets have a deep catalog heritage dating back decades, with options from multiple manufacturers at various price points. I-beam titanium rods are used in naturally aspirated race LS and Coyote applications targeting maximum RPM on nitrous or high compression.What rod length do I need for my LS engine?LS rod length depends on the speci...

Eagle Specialty Products has been a trusted manufacturer of high-performance forged and billet engine components for over 35 years, producing connecting rods, crankshafts, piston rings, and rotating assembly kits that engine builders rely on when stock parts are no longer adequate for the power level being chased. The brand's 4th generation H-beam connecting rods, known as the 4D design, address the most common failure points in previous-generation rods by increasing big-end rigidity through thicker webbing and an improved beam profile that resists bending under high cylinder pressure. Eagle rods are 100 percent CNC machined from 4340 chromoly steel, include ARP 2000 rod bolts as standard, and are popular for both street-strip builds and dedicated track-day engines on a range of domestic V8, LS, and sport compact platforms. Builders who want proven rotating assembly reliability without custom billet pricing consistently choose Eagle as their go-to rod supplier.Popular UpgradesEagle'...

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...
