Cummins 4995602 Genuine Complete Rocker Assembly

Got these to replace my galled ones. Updated design from the older plastic tips and these had updated oiling grooves on the trunions. Check them carefully. The wonderful tooling they use in india left me unimpressed. Had to polish trunion surfaces on 3 out of the 12 arms. (I replaced the trunions with the upgraded mantons as well). Otherwise, XDP shipped them quickly and received them undamaged.

I ordered 6 rocker arm assemblies for my 5.9 on a Monday. I paid for 3 day shipping to be assured they would be here by Friday for the weekend. They shipped 4 from Las Vegas that were here on Wednesday and back ordered the other 2. I called to see if the other 2 would make it by Friday and it didn't seem to be the case. I wanted a full refund of the shipping and was told that it would be prorated since 4 did come right away. It wasn't until I threatened to return all six within the 30 day period and order them from somewhere else that I was assured the last 2 would be overnighted to me by Friday at their expense. It took some arguing and going to a supervisor. The rocker arms are by the same manufacturer but are of different eras or something. I think that will be OK. They made good ultimately.
