Learned this one the hard way - aftermarket injectors vs OEM on a Cummins

Had to choose between saving $600 on a set of reman injectors or shelling out for new ones from Cummins direct. Picked the cheap route on my '05 Ram 2500 about 4 months back. Truck ran okay for maybe 2 months then started getting this weird stumble at idle. Pulled the codes and three of them were already throwing balance rate faults. Now I get to do the job twice. My buddy at the shop told me not to cut corners but I didn't listen. Anyone else been burned by aftermarket fuel parts on a common rail truck?

Read a thread where a guy had the same issue with reman injectors on a Duramax.

same issue with reman injectors" - yeah I've seen those threads too but honestly half the time its just people freaking out over nothing. Most reman parts are fine if you get them from a decent place. People love to blame the injectors but it could be anything like fuel pressure or bad lines or even just bad fuel. Ive run reman injectors on my old truck for like 4 years now with zero problems. Unless you're getting them from some random guy on facebook marketplace you're probably fine.

@averymartin people get way too worked up over reman stuff. A bad install or dirty fuel system causes way more headaches than the injectors themselves. Stick with a known brand and you'll be fine.
