Callies Compstar H-Beam Connecting Rods Big Block Chevy

Callies Compstar H-beam connecting rods for Big Block Chevy engines are forged steel rods built for high-horsepower street, stroker and race builds. Compstar rods were designed from the start for stroker engines and higher power levels. Each rod is machined from heat-treated, stress-relieved 4340 alloy steel. They are often chosen for performance engine rebuilds and for builds that use a stroker crank.

Key Features:

• 4340 forged steel construction: Fine-grained 4340 material gives high tensile strength and fatigue resistance.
• H-beam design: A strong, proven beam style for high-output engines.
• Stress-relieved and heat treated: A multi-stage process helps the rods hold their dimensions through repeated teardowns and rebuilds.
• Shot-blasted, stress-riser-free surface: The rods are fully machined, and the finish adds surface strength and crack resistance.
• Stroker clearanced: The design gives clearance for stroker applications.
• ARP rod fasteners: ARP bolts clamp the rod and cap together at the critical mating joint.
• Bushed wrist pin end: Deformation-resistant bushings support floating wrist pins.
• Made with precision: The rods are finished and sized at Callies' plant in Ohio for consistent, repeatable results.

Callies has a long record of building connecting rods and crankshafts for performance and racing engines. Compstar rods give engine builders a dependable, durable rotating assembly component for a reliable build.
