I have a 2003 tacoma 4x4. Stock suspension. I just dont understand why these shocks would not fit? please help quick i need to find new ones quick and i like these because they provide lift along with better ride

 

If you watch the video about them it says that and when I enter in my vehicle it tells me this product does not fit

 

I didn't see anything about it either, plus it's 4 wheel parts & not meaning to bash but the ones near my place suck, actually might as well be thieves those counter rats will try to sell you what makes them money, not what you want or need...

Piss on their video, what is it you want to do with your truck, pretty sure theres enough input here to steer you in the right direction & FWIW I'd deal with another shop if you have a choice...
