FAQ
Will this fit my 2003–2018 Cummins?
Yes. It covers 5.9L (’03–’07) and 6.7L (’07.5–’18) Ram 2500/3500, plus Ram 4500/5500 (’08–’18).
How many do I need?
Six pairs per engine (one pair per rod).
What does “-.026 mm” mean?
It’s for crank journals ground 0.026 mm (0.001") undersize; confirms bearing sizing.
How is this different from HX?
H-Series is the base performance spec; HX variants add extra oil clearance on standard-size journals (not the same as undersize bearings).
Any install tips?
Measure journal size & bearing clearance, verify surface finish, and follow Cummins/MAHLE torque & lube specs.
