2014 Sierra/Silverado Front rotor Dimensions

[Pinnacle]

Does anyone here know the dimensions of the new rotors? I mean everything about them the offset bolt pattern(same as previous gen) etc etc. I'm on a mission to find out if the new rotors fit the 07-13 trucks, if they do its a big deal.

Looking at the part numbers of rotors and calipers on rockauto, the 13 and 14 trucks looks identical. I'd buy a cheap rotor from a local auto parts and compare it to what I have just to be sure.

The brake pads are the same part number for 2013 1500 and 2014 1500, so I am willing to bet that the new Duralife rotors are a direct fot for the 900's.

I'm also "pretty sure" but that wont cut it. I have been to every dealer looking for a 2014 rotor and none stock them. The offset of the new ones is what I'm after as the coil overs on the new trucks are different.

I just swapped out the OEM rotors/Pads on my GMT900 2013 Sierra with the 2014-2016 Duralife front rotors, and the 2014-2016 GM pads. The braking difference is noticeable. My original pads were only worn 1/16" in 23k miles including several road trips towing cars. The pad life on these trucks is very good. My original rotors were slightly warped, and thus beginning to shake at high speeds, especially when hot, so off they went.

 

 

 

The part numbers for those interested:

 

 

 

Pads 23135915 or AC Delco 171-1129 $112 list $71 wholesale

 

 

 

Rotors 23144340 or AC Delco 177-1163 $136 list $86.36 wholesale

 

 

 

This was 100 percent direct bolt on with absolutely no modifications necessary to the truck. This includes the supplied brake pad anti rattle spring clips.
