King of the Hammers

Mopar Power Goes Off-Road

For a second consecutive year, Mopar, Fiat Chrysler Automobile’s (FCA) service, parts and customer-care brand, supplied six GEN III 5.7 liter HEMI® crate engines to power the unique Spec class 4x4 vehicles to allow off-road enthusiasts to compete in the “Every Man Challenge” race category at the 2015 Nitto “King of The Hammers” in the southern California desert.

Hosted by the ULTRA4 Racing Series, the week-long event, featuring four competitive classes, combines desert racing and rock crawling and is built around what many consider the toughest one-day off-road race in the world. Held every February since 2007, the contest takes place on public lands in Johnson Valley, Ca. in an off-highway vehicle area known as “The Hammers.”

This year, competitors attempted to complete laps over the treacherous and variable terrain of a 215-mile race course. The circuit incorporates high desert track conditions with the infamous rocky canyons and trails from which the event takes its name. The event drew more than 55,000 spectators with an additional 700,000 tuned into the online HD broadcast that was steamed live on the ULTRA4 Racing website and also accessible via

The “4700 Spec Class” was created in 2014 for the “Every Man Challenge” race category with Mopar’s GEN III 5.7 liter HEMI® crate engine powering all six unique 4x4 entries that have been built with a custom tube frame design based loosely on a Jeep® Wrangler, and each equally outfitted with the same best industry-leading parts the off-road world has to offer.
