- Connecting rods are double-forged to maintain superior dimensional consistency through improved grain flow
- Shot-peening eliminates residual stresses and smoothly blends the rod forging surfaces
- Corrosion-resistant surface treatment
- Top and bottom end rod bores case hardened to 58-62 RC to optimize bearing running surface
- Crank pin bearing radial running clearance is optimized to ensure maximum performance
- Precision honing ensures ultra-round bearing surface
- Precision-engineered oiling slots maximize rod strength and bearing life
- Double-drilled small ends provide the piston pin with extra lubrication and cooling, reducing distortion of top end due to thermal transfer from the piston
- Silver-coated bronze phosphor thrust washers with dimpled design increase oil retention and reduce friction between rod and washer interface
- Crank pin bearings are manufactured with the highest-quality hot-rolled steel — case hardened to 58-62 RC
