Callies CSB6535ES3B9AH - 6.535" Compstar H-Beam Big Block Chevy Connecting Rod

Description

Better by design, Callies Compstar connecting rods offer high performance and a trouble-free engine build. Concerns about out-of-round, big-end bore sizing, repeatability, time-saving details, and upgrade costs are a thing of the past. These rods undergo a thorough stress-relief process along with burnishing of threads and bolt spot faces to ensure dimensional repeatability across repeated teardowns and reassemblies. Pin bushings are chamfered and honed, parting line edges are generously chamfered, and bearing locating tab slots are deburred to save you valuable prep time. Stroker clearances come standard, delivering high-strength reliability and peace of mind straight out of the box.
