Hello Larry,

I am really glad you found these brakes, they are exactly what you need when you are towing a heavy trailer!

The great news is that for the front of your 2021 Ford F-150, whether you have the 336 mm or 350 mm rotors, you will still use the same kit. You will want the Timbren BES Brake Upgrade Kit with Disc Brake Pads and Rotors - Front Wheels # T43HV.

Now for the rear, that is where you are going to need to do a quick measurement. I attached an image showing you exactly where to measure so you can easily figure out which size you have.

If you measure 336 mm, you will want the Timbren BES Brake Upgrade Kit - Rear Wheels # T65HV. If you measure 350 mm, you will want # T75HV.

And if you ever need replacement pads down the road, pun intended, you will want the Timbren BES Disc Brake Pads - Front Wheels # T67HV for the front and # T54HV for the rear. The rear pads are the same whether you have the 336 mm or 350 mm rotors.

I really like these brakes for a truck that is doing some heavy towing. The OnyxBite brake pads give you a stronger initial bite and are made to handle the extra heat you build up when towing, helping your stopping power stay more consistent. The G3000 premium raw iron rotors have the OnyxBond matte black coating to help fight off rust from road spray, moisture, and winter conditions. Basically, OnyxBite helps you stop and OnyxBond helps protect your rotors.

What kind of heavy trailer are you pulling around with your F-150?
