When my PS pump went out, I put on a reman one. Lots of people told me not too and they were right. The thing lasted a little over a year.
When it came time to replace that one, I had to decide if I wanted to put on: another reman, a new OEM unit, or put on a Saginaw pump. I went Saginaw.
I have been more than extremely happy with the unit (can you tell I like it?). With 33s, I felt the stock unit was barely adequit and with possibly larger tires in the future, would definately not be up for the task.
Anyhow, bought a bracket from Iron Pig Offroad. Also bought the wide Saginaw pump pulley so I could run a stock width belt. Easy bolt on. It was more work to take the old one off than put the new stuff on. Heck, the high pressure line even screws right into the Saginaw (I was surprised).
Anyhow, works great. Lots of boost. Some people don't like that much assist, I do.
