Callies COMPSTAR Connecting Rods
Designed and produced with engineering and finishing advancements, Compstar connecting rods have what it takes to make your engine build trouble-free and your finished product reliable. Produced from heat treated and stress relieved 4340 material, our H-beam Compstar rods are fully machined with a shot blasted Stress Riser free surface. Finished and sized in our plant in Ohio, every detail of this highly stressed component has been carefully analyzed to maximize repeatability and dependability. ARP 2000 bolts are standard. All lengths are stroker clearanced. See for yourself why Compstar can improve your bottom line and reputation!
Big End Bore Sizing
Compstar rods maintain dimensional repeatability through use of a lengthy stress relief process, and multiple re-torque processing. The combination of the release of residual machining stresses and burnishing of threads and bolt spotfaces ensure that big end bores stay round regardless of how many times your rods are disassembled and re-assembled.
Compstar connecting rods have the most common prep work already done for you! Pin bushings are chamfered and honed for proper high performance oil clearance. Parting line edges are generously chamfered to resist scraping during insertion of the bearing shells. The bearing locating tab slots are de-burred to ensure the bearing tab is fully seated for trouble free installation.
No Costly Upgrades
Compstar rods were designed with higher HP stroker motors in mind from the start. Bolt upgrades and stroker clearance (normally additional cost options with other MFG's rods), are standard with Compstar rods.
The Compstar engineering staff has worked very hard at reducing weight without sacrificing strength and durability. 3D solid modeling software has enabled us to refine our design while monitoring predicted weight, resulting in a very high strength to weight ratio.
ARP 2000 bolts are standard unless noted otherwise.
All Rods have 7/16 Rod Bolts (exc. SBC w/Honda Journals which have 3/8 rod bolts)
HD Series Connecting Rods
Compstar Heavy Duty connecting rods are built for high horsepower, high RPM, big displacement engines. Numerous design features found only on more expensive custom connecting rods have been incorporated into the Compstar HD Rod. As demanded by their High Value design criteria, Compstar engineers carefully examined every square millimeter of these components, leaving nothing to chance. See for yourself:
These added features combined with recognized precision by Compstar make the HD connecting rod the best High Value rod in the market today.
