This product has a complete different dimension as it has been advertised. I don't see any problem with the product itself: however, I am very surprised to see that it is much smaller than what has been described on Amazon. The actual dimension is about 8x7x2. You can find cheaper one in this dimension. I think the company is misinforming customer into buying this! By giving you the wrong information, it can charge you twice as much. Buyer be aware!

It works, had no fitment issues. The only complaint I have is some bent fins that were purely cosmetic and it feels cheap but on the bright side it was cheap and I have a swb regular cab so I can chalk it up to weight reduction. If it still works in 5 years I'll give it 5 stars
