Wilwood Rotor-GT48 SPC-37-LH 12.88 x 1.10 - 12 on 8.75in (Black Electro Coat) for 2008-2021 Ford F650/F750

This Wilwood GT48 left-hand directional rotor provides reliable stopping power for medium-duty Ford F650 and F750 trucks. Measuring 12.88 inches in diameter by 1.10 inches thick with a 12 on 8.75-inch bolt pattern it fits 2008-2021 4x4 models in rear disc brake conversions. Curved vane design and slotted surface channel heat away from friction zones to deliver consistent brake performance under heavy hauling or towing.

Key Features

  • GT48 Curved Vane Core: Internal vanes direct cooling air through the rotor to dissipate heat quickly and resist warping during prolonged heavy-duty use

  • Type-3 Black Electro Coat Finish: Shields against corrosion and rust in road salt or wet environments to prolong rotor service life
  • Directional Left-Hand Design: Rotation-optimized vanes sweep debris outward for even pad wear and peak braking efficiency
  • Precision Dimensions: 12.88in OD x 1.10in thick with 12x8.75in bolt circle for direct fit in Wilwood heavy-duty rear brake kits
