And therefore . . . ? I'm not sure if this is meant just to provide a link to the kit, or to respond somehow to the warranty discussion?
I'll go ahead and address it like it's going to the warranty issue. Yep, from the webpage: "The Lift Kit warrantor is the Lift Kit manufacturer, not Mopar, Chyrsler Group LLC, or the dealership selling the product."
The PDF of the "limited lifetime warranty" manual available on the website won't open for some reason, but the Mopar performance parts catalog (which sells these lifts) is clear that they're sold with no warranty of any kind whatsoever by Chrysler or Mopar.
So again, as far as I know Mopar lifts come with no warranty from Chrysler. Any warranty you have on the parts is from the manufacturer (as would be true of any brand of lift) and any warranty you have on the install is from the dealer (as would be true of any reputable shop).
Thus, unless you're getting some kind of crazy deal from the dealer (unlikely, even if you believe you are) or unless you're simply willing to pay for the convenience of getting a lift installed by the dealer rather than having to do it yourself or find a new shop, there's really no reason to get a Mopar lift.
