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 additional compatibility 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. Notes: Kit is provided with your choice of either 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. 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 OD of the flange flange must be machined such that the face diameter in contact with the rotor is no greater than Ø5.69" or else it may interfere with the rotor and not allow it to seat properly, resulting in a potentially unsafe condition. 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.
