Yerf Dog Spiderbox Refurb Package

American Made Go-Kart

Yerf Dog manufactured 75,000 Spiderbox buggies between 2000 and 2005.  The vast majority of these are still usable.  Even ones that people have left sitting in fields in the sun and rain for the past five or more years.  We hear stories everyday of people purchasing a Yerf Dog for $100, or $200 or $300 and are doing a complete refurb on it.
