Product Information

Product Details
Part No. G12256SD
Warranty Details (2 YR REPLACEMENT IF DEFECTIVE)
Carquest Frontline brake rotors are manufactured to withstand severe-duty use, making them the ideal choice for police, emergency vehicles, fleet and severe duty applications. Machined, balanced and with more carbon content, Frontline severe-duty castings meet or exceed original equipment specifications, delivering better stopping power, superior heat dissipation, and high tensile strength. Carquest Frontline rotors are fully coated to protect against corrosion and rust build-up, which can shorten rotor life. These rotors are the preferred choice when looking for the best performance on severe-duty applications.

Product Features:
  • Designed for severe duty performance
  • Coating promotes unrestricted heat venting by preventing rust and corrosion build-up
  • Manufactured to exact quality and dimensional specifications for superior stopping power
  • Exceeds ISO manufacturing guidelines (International Organization for Standardization)
  • Optimal metallurgy and casting thickness to prevent warping
  • OE vane configuration to dissipate heat and increase pad life
  • Proper harmonic design helps to reduce brake noise

GREAT PRODUCT
Verified Buyer -
Young lady at the counter was very helpful.
Good Product non caring store ( not this one)
Verified Buyer -
These are rotors.
Time Will Tell
Verified Buyer -
Just installed these on my Dodge Ram 1500 last week before a trip in the mountains. They appear to be very well made and my truck stops very well. Since I'm running these with ceramic brake pads, the real story will be how well they hold up over time and if the black finish actually helps prevent rust as claimed. But for now, they are working well.
Rotors installed easily
Verified Buyer -
So I just installed these on my 2007 Chrysler Aspen. The previous rotors were out of spec by at least 3/16 of an inch. Obviously the pads and rotors where in poor condition and you could really feel it when you were breaking. So I'm hoping in the next year or two things will improve greatly with these rotors. Time will tell.
