Hopefully someone can answer this. I plan on changing out my rotors for OEM type replacements. The 04 FX4 supercab has 80K miles and has had the same rotors since they were replaced under warranty at 15K miles. Truck now only sees 2500-5000 miles per year now and I really have an itch to replace the truck with a newer model. I've used the Wagner thermo quiets since 2006 and plan on using them again with the new rotors.

So.. with that said. I've done some searching on sites like rockauto and noticed that some rotors are separated by HD payload and non HD payload. What is the difference. Also.. I'm pretty sure the stock rotors are the 12.99" rotors, but can someone just verify that for me.

Thanks...

HD payload F150's have 7 lugs, regular payload F150's have 6 lugs.

 

I would agree on the 7 lug wheels being the difference.

I know the front brake pads are the same HD payload or Standard F150
