This KORE3 billet hub kit was designed for GM short-spindle applications, which includes all 1964-1972 GM A-Bodies, 1967-1969 GM F-Bodies, and 1968-1974 GM X-bodies. Please refer to the GM Big-Brake Application Chart for additonal compatability and application specific notes. KORE3 hubs are a clean, strong, lightweight solution for anybody wanting to run slip-on rotors on their GM short-spindle equipped car. Hubs were designed to complement the KORE3 big-brake conversion kits.

  1. Kit is provided with your choice of either ARP M12x1.5 press-in or 1/2-20 screw-in studs and bearing races pressed in as standard. Billet aluminum grease caps come as standard with this hub kit.

  2. KORE3 billet hubs are interchangeable with most GM, OE, short-spindle drum hubs, however the OE drum hubs must be modified in order to be used with the KORE3 big-brake upgrade. The outside diameter of the flange must be machined to Ø5.85" or else it may interfere with the rotor and not seat properly, resulting in a potentially unsafe condition.

  3. KORE3 billet hubs with a C5/C6 rotor in place increase track width .200" [5mm] per side over stock drum applications, making the overall track width .400" [10mm] wider than stock. Track width is decreased .240" [6mm] per side compared to the stock disc applications, making the overall track width .480" [12.2mm] narrower than stock.
