Did you know that we can build almost every Forgeline wheel for centerlock applications? Even if you don’t see a centerlock version explicitly listed on our website, most of our models (with a few exceptions) are available for centerlock fitments. This 21-inch Forgeline one piece forged monoblock RB1 was engineered for a Dodge Challenger Hellcat with our Flush-Loc centerlock conversion kit and finished in eye-popping Transparent Copper!
