Sorry, no we do not make an extension for our crossbars. If you need longer bars to accommodate your load you will need to purchase new bars.
Our classic round bars come in the following sizes: 48, 58, 66, 78, and 86" lengths.
Our new aero bars (CoreBar, JetStream) come in the following sizes: 50, 60, 70". We also offer an 80" in the CoreBar.
