I like these trucks on 35s personally, it just looks right. Get a 4-6 inch lift kit. If you get a leveling kit, you would be wanting a bigger lift eventually. I have a 6 inch and i already want a 10-12:D
Ok I thought you were doing on of the jiffy lube type of "engine flushes" that makes sense. But still you can mix dino and synthetic without really needing to do an engine flush. If the oil is nasty, which in diesels it tends to be, then maybe its not that bad of an idea.
never heard of them. maybe they get their products cheaper so they sell it to you for less. Although I would tend to agree with you on the fact that if its made cheaper then it is cheaper, that may not always be the case.
if you haven't changed them yet, you might want to with a 2002. I believe they last up to 4-6 years with constant use, but that is not to say they can't last longer. If your starts are ok then there should be no problem.
