Ok, so we don't have any info on these rocker boxes by Rocket Bobs, other than the fact that they are available for Harley-Davidson Twin Cam motors. They are called 7075 Rocker Boxes, and they look dope as hell. We saw them posted on Instagram, and we wanted to share them with you. That's all we got at the time of this post. When we get more info, we'll post it. Until then, visit their website and demand more info!
