I can't figure this out.....I wanted to buy Bosch QuietCast rotors for my 2003 F250 4x4. O'Reilly's website shows part number 20010312 is for 4x4 front with 13" diameter. However, this same part on ebay, Bosch, Amazon, and others says that 20010312 does not fit my truck. Has anybody replaced a stock 13" rotor on their truck with 20010312 as a direct fit replacement or is O'Reilly's website incorrect?

Thanks,

Accordng to Amazon, you should be using the Bosch 20010365 QuietCast Premium Disc Brake Rotor for the front and the 20010310 for the rear.

 

Right - that's the confusing part. I have 16" rims and 13" rotors. That part (20010365) is the 14.5" diameter rotor, which is for 17" or 18" rims, as I understand it.

I wonder if 2003 F250s had different sized rims from the factory - some 16" and some bigger than 16"??

 

This may or may not apply in your situation. But it's been my experience that the application charts on ebay, Amazon, etc. are often vague and inaccurate.
But if reford's taken the time to look into it and post, I'd go with his numbers.

 

Thanks, I've never had a problem with O'Reilly, Advance or Autozone indicating that a part fit and then it didn't. I've not bought enough from the ebay/amazon type stores to know. But what I do know is that the part Amazon says fits, does not. There's not enough room for a 14.5" rotor plus the caliper on a 16" rim. At this point, I'll probably just go with Wagner or something else.....

Thanks for the inputs,
-Chris

 

Just as an update for future searchers, O'Reilly's database was correct for my truck and the 13" rotors worked just fine. part number 20010312.
