@Crusher Yes it will. The Assault Rear Fender should come with 70mm bolts to accomodate this new shock bracket. The shock bracket comes with 60mm bolts for those that are not running an Assault Rear Fender. Since the Clevis brackets for the SL and Base are different, this shock bracket will now allow the base model SLingshot to run the Assault Fender if desired.
Welcome aboard! Glad you came to the light!
