The Toughest Off-Road Race of the Year?

The Race We’ve All Been Waiting For

We’re kicking off 2021 with one of the biggest and toughest races of the year: King of the Hammers. Held every year on BLM land in Johnson Valley, California, the race has attracted the best and most extreme off-roaders competing in classes for dirt bikes, SXSs, ATVs, and the famous Ultra4.

In the Ultra4 class, “All cars must be capable of 4-wheel drive. Beyond that, the class is unlimited. These cars come in all shapes and sizes and are capable of speeds over 100+ MPH and still contain gear ratios as low as 100 to 1 for technical rock crawling.”
