Bob Bunker Jr.

Bob Bunker Jr. is the son of legendary West Coast doorslammer pioneer Bob Bunker Sr. aka the "Folsom Flash". Bob Jr. got his start building doorslammer chassis' in 1983 while working for Chris Alston.

In 1988, Bob Jr. ventured out on his own starting Bunker Motorsports while refining his own, unique chassis design and perfecting it over the years.

Along with building hundreds of race cars over the past 30 years, Bob Jr. has also driven his fair share of cars  from a blown alcohol funny car and altered to a handful of Pro Modified cars ranging from a one-of-a-kind Lamborghini, a 1957 Chevy, 1941 Willys and he took over the driving duties of the iconic Bunkers Beast 1955 Chevy for a few years.

Stay tuned for a rebirth of the "Bunkers Beast / Folsom Flash" which is currently in the works. It is a car that has always been a staple to the entire Bunker family, and as a family a new version will soon hit the track!
