You asked for it and here it is, the KORE3 billet hub kit for GMPU C10/G10 spindle applications with 5x4.75x2.78 wheel patterns and SET5(1.375")/SET3(.844) inner and outer wheel bearings. These hubs are compatible with with the heavy-duty 1971-1987 C10/G10 and 1971-1976 B-body applications, and are a clean, strong, lightweight solution for anybody wanting to run a high performance slip-on rotor brake kit. These hubs are designed to complement KORE3 C5/C6 Corvette based big-brake kits and are directly compatible with C5/C6 rotors without modfiication.

  1. Does not require the use of modified C5/C6 rotors since the wheel pattern and register diameter properly match the factory C5/C6 rotors.

  2. KORE3 billet hubs decrease track width .03" [.8 mm] per side over stock applications when used with C5/C6 components, making the overall track width .06" [1.6 mm] narrower than stock.

  3. Compatible with 1971-1987 GMPU C10/G10 spindles that used Ø1.375" (SET5) inner and Ø.844" (SET3) outer wheel bearings. These KORE3 hubs are not compatible with LD GMPU spindle applications that used the smaller SET6 (1.25") inner wheel bearings and had the thinner 1" rotors.
