Kore3 GM Tall Spindle Front Hubs with 5 x 4.75″ Bolt Circle, Pair.  Billet 7075 aluminum hub, billet aluminum dust cap, M12x1.5 ARP Studs, Timken Bearings and Races.  Fits GM B-Body ’77 – ’96 including Chevy Impala, Chevy Caprice, Buick Roadmaster, Oldsmobile Delta 88, and Cadillac Fleetwood.

This KORE3 billet race hub kit was designed for GM tall-spindle and GMF3 spindle applications with the larger .844″ outer bearing journal diameter. Please refer to the GM Big-Brake Application Chart for vehicle compatability and application specific notes. KORE3 hubs are a clean, strong, lightweight solution for anybody wanting to run slip-on rotors on their GM tall-spindle equipped car. Hubs were designed to complement KORE3 big-brake kits. Notes:
Hub kit is provided with ARP wheel studs, bearings, and seals based on what is selected from the pull down menu below. Wheel studs options are 1/2″-20 screw-in ARP Wheel Studs or M12-1.5 press-in ARPwheel studs. Press-in studs are installed by KORE3 while screw-in studs are shipped loose. Billet Grease Caps are included as standard.

KORE3 billet hubs decrease track width .03″ [.8 mm] per side over stock applications, making the overall track width .06″ [1.6 mm] narrower than stock.

All GM tall-spindles with SET6 inner wheel bearings are compatible with KORE3 tall-spindle big-brake conversion hub and bracket kits. GM made two primary versions of the tall-spindle (non-ABS), Ø11″ and Ø12″, as they are typically described by the nominal diameter of the brake rotor that originally fit each respective spindle. Thus, GM Ø11″ and Ø12″ tall-spindles are virtually the same spindle, just with slightly different cast caliper mounts to accomodate different size rotors. Again, the Ø11″ and Ø12″ dimensions denote the nominal rotor diameter, not the spindle itself. Since the cast caliper mounts must be removed (cut) from the spindles for installation of the KORE3 big-brake caliper bracket kit and C5/C6 components, either tall-spindle is equally suitable.

Note: GM tall-spindles came in two variations with respect to the outer wheel bearing size. The outer wheel bearing journal diameter of the spindle may be either Ø.750″ [Ø19.05 mm] or Ø.844″ [Ø21.44 mm], and these hubs are only compatible with the .844″ variants.

Kore3 GM Tall Spindle Front Hubs with 5 x 5″ Bolt Circle, Pair. Billet aluminum hub, billet aluminum dust cap, M12x1.5 ARP Studs, Timken Bearings and Races. Fits GM B-Body ’77 – ’96 including Chevy Impala, Chevy Caprice, Buick Roadmaster, Oldsmobile Delta 88, and Cadillac Fleetwood.

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.

Notes:
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 – we offer our in-house CNC machined PowerStop rotors.

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.

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.
