You asked for it and here it is, the KORE3 billet hub kit for GM B/D-body tall-spindle applications. This hub kit picks up where our standard billet hub kits left off and have been optimized specifically for the Impala SS, Caprice, Roadmaster and other compatible models. KORE3 hubs are a clean, strong, lightweight solution for anybody wanting to run slip-on rotors on their GM B/D-body with the option to maintain ABS functionality and are designed to complement KORE3 C5/C6 Corvette based big-brake kits.

  1. Requires the use of modified C5/C6 rotors to properly mate with the 5 x 5" wheel pattern and Ø3.06" [77.8mm] pilot register. Click LH or RH for respective rotors.

  2. KORE3 HD 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 GM tall-spindles that used Ø1.250" (SET6) inner and Ø.844" (SET3/SET34) outer wheel bearings. KORE3 HD hubs are not compatible with early tall-spindle applications that use the smaller SET2 (.75") outer wheel bearings.
