THE DAWG
Don't equate my amusement with the sales effort to any particular expectation of failure with the part Mike. I don't see a problem with the part vis-a-vis its basic function. I don't see enough to justify the price difference; but that's my own relative judgment.
The hyperbole about performance gains and noticeably better running engines coming from the chain tensioners is still, to me, more smoke than fire. But that doesn't mean as a chain tensioner they aren't a perfectly satisfactory part. That being so there's no particular reason not to go with them if one is wanting to do every possible thing they can (the manufacturer notwithstanding).
Personally I don't see in the cost versus benefit analysis enough to justify paying such a premium over the stock part. The stock part hasn't been doing a bad job. And these are new enough we have no idea what their wear pattern or duration will be over time.
The (albeit normal) hyperbolic advertising claims are amusing. The sales claims from the shops to sell the more expensive and higher margin part are amusing as well. Though not unexpected. It really is just part of doing business (at least here in this market; though across the larger markets as well). I still remember magnets for fuel lines and finned widgets for air cleaners and myriad other gadgets on gas station shelves in the 60s and 70s. Claims are easy.
In this case the part is actually (probably) a perfectly satisfactory part. There won't be issues with its use. I just don't see the likelihood that its benefits over the stock part (minimal or more) justify the price premium. Hell, I look for reasons to find alternatives to MoCo branded parts. But not at the expense of a keystone markup or more for the privilege. For Willie's sake, this is HD pricing we're taking about pricing at a premium over
