Bob Chandler: Full Biography

Bob Chandler is an American off-road racer and shop owner who built the first Bigfoot in 1975 and, in doing so, created the monster truck. He is in four halls of fame and led the sport’s safety body for decades.

Ferguson A former construction worker from the St. Louis area, he began racing his family’s 1974 Ford F-250 in 1975 and kept breaking it. Midwest parts shops did not stock what he needed, so he and his wife Marilyn opened their own with their friend Jim Kramer. The truck grew bigger as he tested parts on it, and it took the name Bigfoot from his heavy-footed driving.

Car Crush In 1981 he drove Bigfoot over two junk cars in a field and filmed it as a joke. A promoter saw the tape in his shop and asked him to do it in front of a crowd. He hesitated, worried about how destructive it looked, and then agreed. The first public car crush followed, the sport followed from that, and Ford backed Bigfoot from 1983 to 2005.

Safety By the mid-1980s there was a fleet of Bigfoots and a field of imitators. Chandler answered the arms race over size with Bigfoot 5 and the arms race over risk by co-founding the Monster Truck Racing Association in 1987. He taught himself computer-aided design, patented a suspension that transformed how the trucks handled, and co-invented the remote kill switch that every monster truck now carries.

The Career

Three Chapters That Defined Bob Chandler

Chapter 01

Ferguson

He was a construction worker who went four-wheeling at weekends, and he broke the family's 1974 Ford F-250 often enough that finding parts in the Midwest became the problem. He and his wife Marilyn opened Midwest Four Wheel Drive and Performance Center in Ferguson, Missouri, with their friend Jim Kramer, and the truck became the shop's test bed and advertisement. In 1979 he replaced its whole under-assembly with a military-surplus set with four-wheel drive, four-wheel steering and enormous tyres. The name came from his own driving: heavy-footed, and hard on parts.

Chapter 02

Car Crush

In 1981 he put two scrap cars in a field and filmed himself driving over them, for his own amusement. He played the tape in the shop, a promoter watched it and asked him to repeat it in a stadium. Chandler hesitated, because he did not like the destructive image it would give the truck, and then said yes. What followed is generally regarded as the first public car crush, and it created an entire sport. Ford sponsored Bigfoot from 1983 until 2005, and by the mid-1980s Chandler had a fleet of trucks and a field of imitators, many claiming to be the largest. He answered that in 1986 with Bigfoot 5, built around tyres bought from a Seattle scrapyard that the US Army had used on an overland train in Alaska.

Chapter 03

Safety

The more interesting answer to the imitators was engineering. Chandler taught himself computer-aided design, and in 1989 used it to draw a tubular chassis with a nitrogen suspension that gave four times the travel of anything before it, a design he patented and which every modern monster truck descends from. He co-founded the Monster Truck Racing Association in 1987 for the single purpose of safety, and led it for decades. With George Carpenter he co-invented the remote ignition interrupter, the kill switch that lets an official shut down a truck from outside it. Bigfoot stopped running Monster Jam events in 1998 after a dispute over image and footage licensing and has not returned, but it still tours, and Chandler is in four halls of fame.

Chandler is a builder and team owner rather than a career competition driver, so there is no season-by-season race record to give. This table lists the firsts, innovations and honours that his own hall of fame entries and the Bigfoot record agree on. The Off-Road Motorsports Hall of Fame credits him with the self-taught CAD work, the patented cantilever suspension, the tubular chassis and, with George Carpenter, the remote ignition interrupter kill switch; it describes the Monster Truck Racing Association as co-founded in 1987 for the sole purpose of promoting safety, and says he led it for decades. The first public car crush is usually dated to 1982, following the home video he made in 1981. Figures verified 19 August 2026.

Frequently Asked

Bob Chandler: Frequently Asked Questions

Who invented the monster truck?

Bob Chandler is generally credited with it. He began modifying his family's 1974 Ford F-250 in 1975, and by 1979 had rebuilt it on a military-surplus under-assembly with four-wheel steering and oversized tyres, producing what is regarded as the first monster truck.

How did Bigfoot get its name?

From Chandler's driving. He was heavy-footed and broke parts frequently, and the nickname attached itself to the truck.

What was the first car crush?

In 1981 Chandler drove Bigfoot over two scrap cars in a field and filmed it as a joke. A promoter saw the tape playing in his shop and asked him to do it in front of an audience. He agreed after some hesitation, and the first public car crush followed in 1982.

What is Bigfoot 5?

The truck Chandler built in 1986 around tyres he bought from a Seattle scrapyard, which the US Army had used on an overland train in Alaska. On its debut it took the title of the largest monster truck.

What is the MTRA?

The Monster Truck Racing Association, which Chandler co-founded in 1987 for the sole purpose of promoting safety in the sport. He led it for decades and it remains the sport's main safety authority.

What did Bob Chandler invent?

Beyond the monster truck itself: a patented tubular chassis and nitrogen suspension, designed with computer-aided design he taught himself, which gave four times the suspension travel of earlier trucks. With George Carpenter he also co-invented the remote ignition interrupter, the kill switch that lets officials shut a truck down.

Does Bigfoot race in Monster Jam?

No. Bigfoot stopped running Monster Jam events in 1998 after a dispute over the licensing of footage and images, and has not returned. It tours with other promoters instead.

Is Bob Chandler in any halls of fame?

Four: the Missouri Sports Hall of Fame in 2006, the International Monster Truck Museum Hall of Fame with its inaugural class in 2011, the Off-Road Motorsports Hall of Fame in 2013, and the SEMA Hall of Fame in 2019.
