2021 King of the Hammers KoH2021
King of the Hammers? It’s one of the meanest, ugliest, gnarliest races on the planet. What started as a group of friends racing through the car-size boulders of Johnson Valley, California, has evolved into a weeklong event complete with a pop-up city called Hammertown and no fewer than six individual races, all organized by the Ultra4 Racing.
“Innovating the off-road landscape and competing with Bronco’s higher-speed off-road abilities have always been at the core of Bronco brand’s heritage.”Dave Rivers, Ford SUV (Sport Utility Vehicle) marketing manager
“Our new Bronco 4600 racers underscore our motorsports heritage and how the all-new 2021 Bronco can be tuned from the showroom floor to compete in the grueling ULTRA4 stock class series.”
Like the first-generation Bronco that took the 1969 Baja 1000 outright, new Bronco 4600 builds on this winning tradition starting with a 2021 Bronco two-door SUV with stock powertrain running on a competition-tuned High-Performance Off-Road Stability Suspension (HOSS) System.
Ford Performance supplies modified front and rear modular steel bumpers and a Warn ZEON winch, while RIGID LED off-road lights improve night vision.
A custom roll cage by Geiser Brothers and first-ever FIA off-road-certified race shells from Recaro are added inside.
Teintes : Race Red, Oxford White, Velocity Blue
Bronco 4600 race vehicles feature a new livery leveraging factory 2021 Bronco colors – Race Red, Oxford White and Velocity Blue. The front design takes inspiration from the 1969 Baja 1000-winning Bronco, with matte black hood, plus white upper and red lower body lines that transitions into a more modern Bronco design scheme extending rearward.
“Our new ‘war paint’ scheme tells the Bronco race story – up front is chapter one that traces back to the victorious 1969 Bronco,Scott Guan, Bronco designer
then, as you travel along the side, the lines get more diagonal, more futuristic, signaling the future of the brand.”
“Bronco 4600 underscores how ready the all-new Bronco is for competition and how Ford Performance is committed to driving the brand’s success across multiple off-road series.”Mark Rushbrook, global director, Ford Performance Motorsports
“We look forward to off-road racing teams coming to this platform and to Ford Performance stepping up to continuously enhance the state of the art in off-road racing for them.”

Châssis Ford Performance Bronco 4600 ULTRA4

It also features Wilwood Engineering brakes and 35-inch BFGoodrich mud-terrain T/A KM3 tires mounted to Method Race Wheels 202 Forged Beadlock wheels.
