A diesel engine with a i6 design. Used in most dodge ram heavy duty trucks. The engine itself is to powerful for the ram to handle.

Something every girl wishes her man would be driving. The most bad ass diesel engine money can buy especially the 5.9 12 valve which is way better than a power stroke or duramax which usually has 8 cylinders while the inline 6 only has 6 cylinders because the only V that should be in your truck should be riding shotgun. The only reason i would not buy a cummins is if it was a 53 block or you see a typical teenager is selling in and the only upgrades are a 5 inch straight pipe to a 8 inch tip and a 6 inch lift with a edge computer system that makes it roll coal which usually means there is something wrong with it and the dip shit wanna be country boy wasted his dads money and a HELL of an engine.
damn Henry do u hear that hummin?

yeah that must be a cummins.

(5 seconds later) yep there she is smokeing out a 6 ohh

A fairly reliable engine provided you carry gallons of oil with you when your rear main seal blows out.
