Ultra4 Racing and Hammerking Productions are the founders and the driving force behind the toughest one-day off-road race on the planet: Kemcing of The Hammers. 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. This is truly the ultimate test of man and machine! 2015 was the eighth year of King of The Hammers.

To give these cars and their drivers a chance to showcase their unique capabilities, Hammerking has formed the Ultra4 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. The races take place on both public lands and in private motorsports parks across the country.

Out of the five classes of competition-Unlimted-4400, Stock – 4600 , Modified – 4500 , Legends – 4800. We will be competing in the 4500-ultra 4Modified class as this is class that every off road enthusiast can relate to and is relatively inexpensive to compete. In our opinion the 4500 class is getting ready to really take off. With Ultra 4, Dirt Riot and now even the Mint 400 is welcoming the 4500 class. Our goal is to showcase that with mostly off the shelf parts, a group of friends that don’t own a fab shop or major off road manufacture can be competitive or even win. We want to show that is truly a weekend warrior class and help manufactures show case there products. This is a great opportunity to show what your product can do.
