Callies Compstar H-Beam Connecting Rods

Callies Compstar H-beam connecting rods are forged performance rods for engine builders who want dependable strength and a clean, repeatable build. They are made from heat-treated, stress-relieved 4340 steel. They are fully machined and shot-blasted for a stress-riser-free surface. Compstar rods are a popular choice for street performance, racing and stroker engine builds.

Key Features:

• 4340 forged steel H-beam design that is heat treated and stress relieved for strength and durability
• ARP 2000 series rod bolts positioned for pan rail clearance, with added stroker clearance designed into each rod
• Dimensional repeatability from a lengthy stress-relief process and multiple re-torque steps during manufacturing. Big end bores stay round through repeated assembly and disassembly.
• Less prep time because the common prep work is already done. Parting surface edges are chamfered, bearing tab slots are free of burrs, and pin bushings are chamfered before honing.
• Tight quality control, with rods final sized to a consistent tolerance and weight matched for balanced assembly

Compstar rods combine high quality and affordability. Their attention to detail and ready-to-use clearances give engine builders confidence in the finished engine.
