Product Details

The Callies Compstar CSA5850CS2A2AH H-Beam connecting rods are engineered for high-performance small block Chevy applications requiring precision, reliability, and exceptional strength. These forged 4340 steel connecting rods feature a 5.850-inch center-to-center length with a 2.0-inch rod journal diameter, making them ideal for stroker and high-horsepower builds.

Key Features:

  • Forged 4340 steel construction with heat treatment and stress relief for maximum durability
  • H-Beam design optimized for high-revving naturally aspirated and mildly boosted engines
  • 5.850-inch center-to-center length with 2.0-inch rod journal diameter
  • ARP2000 7/16-inch cap screws for superior tensile strength and clamping force
  • Bushed small end with chamfered and honed pin bushings for proper oil clearance
  • 0.960-inch pin end width compatible with Forged Side Relief (FSR) style pistons without modification
  • Stroker clearance design with optimized bolt placement for increased cam and pan rail clearance
  • Typical weight of 587 grams per rod

Callies Compstar rods feature dimensional repeatability through extensive stress relief processing and multiple re-torque cycles, ensuring the big end bores remain round after repeated disassembly. Bolt spotface gussets increase strength and dimensional stability in critical areas. The parting line edges are chamfered to resist scraping during bearing installation, and bearing locating tab slots are deburred for trouble-free assembly. Fully machined with a shot-blasted, stress-riser-free surface finish.
