Welcome to Filthy Motorsports.

Filthy Motorsports is a specialty off-road shop in Boulder, Colorado that specializes in serving off-road enthusiasts that prefer to do the work themselves. While we do offer installation and custom fabrication services, we believe that half the fun of four-wheeling takes place in the garage. To give you the best service possible, we're often available after-hours and on weekends via email and we're constantly adding products to our on-line store for fast, safe, and easy shopping.
