Do these rods work for both 5.9L and 6.7L Cummins?
Yes—DC7559S is designed for 5.9L and 6.7L Cummins applications across 1989–2019 when used with appropriate pistons and clearances.

What’s the difference between DC7559S and DC7559H?
The “S” set includes CARR multiphase bolts; the “H” set uses H-11/WMC bolts. Both are Pro-H rods; choose based on your fastener preference and power goals.

Are bearings included?
No, bearings are not included. Reuse is not recommended—install new bearings to match your crank journal spec.

What power levels are these suited for?
They’re built for high-output street, towing, and competition builds. Final limits depend on tune, fuel, RPM, piston/weight, and assembly quality.

Do I need machine work?
All rotating assemblies should be measured and balanced by a qualified machine shop; verify big-end housing bore, side clearance, and pin fit during assembly.
