ULRTA4 vehicles are like a Tarantula, it will run, jump, climb straight up and roll over just to get back up! Go ahead and try to piss it off, you better hang on! One of the unique purpose-built vehicles in the world, the ULTRA4 car came to be with humble beginnings and has evolved into a formidable off-road machine in a few short years. Most drivers call them the Swiss Army Knife of 4 wheelers. The ULTRA4 is a cross between a Trophy Truck (that runs Baja) and a Rock Crawler, combined together you end up with a vehicle that runs across the desert at 100 mph+ and still contain gear ratios as low as 100 to 1 for technical rock crawling. Climbs a rock canyon some folks would not even walk up!
King of The Hammers is the toughest one-day off-road race on the planet, the best of the best. The ULTRA4 is powered by a LS7 450ci Big Block pumping anywhere from 720HP to 800HP+ making that canyon climb and over boulders with the Spider 9 Axle from Spidertrax.
The Tarantula behind the machine a Diff Shaft with 40 Spline Spool! The price doesn’t include the housing, frickin little monster!
King of The Hammers takes place each year in February, on public lands in Johnson Valley, CA. The race has evolved from 12 teams racing for bragging rights and a case of beer, to more than 300 teams competing before more than 35,000 fans in person and nearly 500,000 watching online. Due to the incredible success of King of the Hammers, Hammerking has created a ULRTA4 Racing Series with seven races held throughout the country.
To give these cars and their drivers a chance to showcase their unique capabilities, Hammerking has formed the ULRTA4 Racing series. The series challenges drivers to compete in a wide variety of terrain from endurance desert racing to competition-style rock crawls to short course racing. Hammerking currently produces seven races in the series.
