Callies Compstar Sport Series connecting rods bring professional-grade engineering to the 1.6L EcoBoost platform found in the 2013-2019 Ford Fusion and Fiesta ST. Machined from fine-grained 4340 steel in an H-Beam profile, these rods ship as a four-piece set ready for high-output engine builds. Choose between ARP 2000 or Custom Age 625 bolt options depending on your power target and application demands.
Big-end bores that stay round, every time. Callies subjects each rod to an extended stress-relief process followed by multiple re-torque cycles. This combination burns off residual machining stresses and burnishes threads and bolt spot-faces so the big-end bore holds its geometry through repeated assembly and disassembly, a detail that matters in any serious rebuild environment.
Prep work done before the box opens. Pin bushings arrive chamfered and honed to proper high-performance oil clearance. Parting-line edges are generously chamfered to prevent bearing-shell scraping during installation. Bearing locating tab slots are de-burred so tabs seat fully on the first attempt, reducing bench time on every build.
ARP bolt hardware included as standard, not an upgrade. ARP 2000 or Custom Age 625 bolts come with the kit from the start, delivering superior tensile strength and clamping force at the rod-cap joint. Bolt placement is optimized for additional rotational clearance in stroker applications at the bottom of the bores and along the pan rails, eliminating the costly clearancing work that many competing rods require as an add-on.
Built with stroker clearance in mind. Contouring above the bolts increases cam clearance and reduces the amount of block clearancing required on the cam side.
Deformation-resistant Ampco 18 wrist pin bushings. Ampco 18 bronze material resists deformation under high-load cycling, maintaining pin-to-bushing clearance and preventing galling across extended use in boosted applications.
Product Benefits
- H-Beam Construction: Fine-grained 4340 steel provides a high strength-to-weight ratio for boosted and high-revving builds.
- ARP 2000 or Custom Age 625 Bolts: Select bolt grade to match the power level and application requirements.
- Dimensional Repeatability: Extended stress-relief and multiple re-torque processing keep big-end bores round through repeated rebuilds.
- Ampco 18 Pin Bushings: Deformation-resistant bronze material maintains wrist-pin clearance under sustained high-load use.
- Pre-chamfered and Honed Bushings: Ships ready to assemble with correct high-performance oil clearance already set.
- Stroker Clearance Standard: Bolt placement and cap contouring provide rotational clearance for stroker applications at no extra cost.
- Cap Gussets: Added material at the bolt spot-face area reinforces the cap where cross-section is thinnest.
- Specs: 134mm Length / 44mm Rod Journal / 21mm Pin.
Note: Fits 1.6L EcoBoost found in the 2013-2019 Ford Fusion and Fiesta ST. Callies Compstar Sport Series H-Beam rods are designed for High RPM N/A or mild boost applications. Verify dimensions are compatible with your build before ordering.
