FAQ
How many do I need?
Most builds use six bearing positions; order the quantity needed for your rods and configuration.
Is this an OEM replacement?
It meets or exceeds OE specs and is designed for performance use; verify standard journal size before ordering.
Will it fit both 5.9L and 6.7L?
Yes—see the fitment years above for Ram 2500/3500/4500/5500 models.
What surface finish/clearance should I aim for?
Follow Cummins/Clevite specs for oil clearance and journal finish; H-Series works well with medium-to-high RPM builds.
