FAQ

Do these rods require any machine work?
Most performance builds blueprint bearing clearances and check side-clearance and balance; consult your machinist for your target power level.

Are H-11 bolts reusable?
Rod bolts are a critical fastener; always follow CP Carrillo’s torque/angle and replacement guidance for your duty cycle.

What power can these support?
Support limits depend on tune, RPM, fuel, and cylinder pressure. Pro-H H-11 sets are commonly used in high-horsepower street and competition Cummins builds.

Will they fit both 5.9L and 6.7L Cummins?
Yes—this set is specified for 1989–2019 5.9L/6.7L Cummins applications. Verify piston/pin specs and bearing sizes during assembly.
