The Lowboy Fork Lowering Kit from Burly makes lowering your 39mm forks up to 2" a breeze. The perfect way to get that low stance you want, or level out your stance after installing a hardtail on your chopper. Kit includes two rebound springs and two 30.5mm OD progressively would fork springs, plus instructions for an easy installation. Progressively wound springs deliver a compliant ride, yet resist bottoming. See Additional Information below for fitment.
