FAQ
Do I need one or multiple pairs?
Each connecting rod uses one pair (2 shells). A 6-cyl Cummins typically needs six pairs for all rods.
Will these fit my engine?
These fit 2003–2018 5.9L/6.7L Cummins applications that require .75 mm undersize bearings. Measure/confirm crank journal grind before purchase.
What’s the material and why does it matter?
A-Series bi-metal (aluminum-silicon) with tri-metal upper provides strong fatigue resistance and improved journal conditioning for rebuilt and workhorse engines.
Can I mix sizes across cylinders?
Yes—each journal can run its required size but never mix different sizes on the same journal.
