• GEOSPEC coating: provides superior corrosion protection over zinc or conventional painting.
• Premium iron castings: built with G3000/G11H18 iron for strength, stability, and durability.
• OE vane configuration: matches the original vane configuration to promote proper heat dissipation.
• CNC-machined and mill-balanced: 100% precision cut for smoother stopping and reduced vibration, with a non-directional finish that promotes faster break-in.

This is a blank rotor with no drilling or slotting, and it installs ready to go with no additional pre-degreasing preparation needed. Sold individually; for even, balanced braking, replace the rotors on both sides of the front axle as a matched pair.
