​The biggest, and most spectator friendly, race of the series is the Metalcloak Stampede. 

Racers from across the country, with famous names like Shannon Campbell, Loren Healy, Jason Scherer, Levi Shirley and Tom Wayes, converge on Prairie City SVRA in Rancho Cordova for two days of hard-charging fun.  (See Racer Bios)

Ultra4 Racing Cars are called "Unlimited" because their is no limitation as to how they are built. From awesome horsepower to massive tires, these purpose-built machines can do 150 mph one second and in the next second climb over massive boulders.

The Baddest Cars.
The Best Racers.
The Toughest Off Road Racing in the World.

Ultra4 Racing (website | facebook) started 10- years ago in Johnson Valley, California when a few guys got together and decided to race some of the hardest terrain in the world.  That race evolved into the world famous King of the Hammers. 

13 years later, Hammerking Productions, the team behind the King of the Hammers, runs races around the world including a series of races on the West Coast called the Lasernut Western Series - each race in the series is a qualifier for the following year's King of the Hammers.


But Ultra4 Racing is about more then just massive horsepower machines. It also has classes for UTV (fast little side-by-sides), Stock (basically a stock rig with some mods, but limited in motor and tire size), Stock Mod (modified stock rigs with bigger engines and 37" tires) and Legends (former Unlimited class cars that have some minor restrictions). 

Each of these amazing classes bring excitement and competitors from all over the region looking for their chance to win one of the toughest races of the year.

Sponsored by Jeep parts & accessories manufacturer Metalcloak, based in Rancho Cordova, just 10 minutes from Prairie City, the Ultra4 Stampede promises to be one of the region's top motorsports events.
