Cummins ISX cheaper parts

[Optimanzltd]

In the past I have used PAI mack parts and cummins Big Cam III inframe kits and never had a problem. I also used to buy lots of detroit engine parts and especially fuel gear parts from Interstae Mcbee, and gentleman Casey Garcia used to call on us in New Zealand once a year, and never had an issue with them either. Big name developing a lot of stuff themselves. having said that I hope they kept up their quality and haven't gone to corporate.
