My alt. is the CS series. CS144HO is the part name. Although, I doubt this is what you will want for your truck. Depending on whether or not you are going to add more amperage to your truck besides your compressors you may or may not need more than what I have. I'm sure you would be able to figure out your amp draw from the applications you will be having. And always, it does'nt hurtb to have more than what you need! No, my alt. was $400, not $500.
I just bought my weber carb for $320, a little piece of damn metal that I cannot comprehend on why its so much. Same with the alt. But it don;t matter to me, it is necessary IMO.
I just suggest getting on the phone and having someone help you pick one out. Regardless, you will get what your looking for! Good Luck!
