Ultra4 Cars For Sale

The name of this class says it all: these cars really do go beyond all others, exceeding expectations! The Ultra4 Series, governed by Hammerking Productions, contains four classes: 4600 cars (also called "stock") are built on stock production chassis and bodies with few modifications permitted, allowing drivers to compete in vehicles that closely resemble their street-legal cousins; 4500 cars ("mod" class) are also built on stock production chassis and bodies, but are allowed limited modifications; 4800 cars, or the "legends" class, are a tamer version of the 4400 cars, the class that is essentially unlimited and the "King" of the series. All classes run at the King Of The Hammers (KOH) races held in Johnson Valley, Ca every February.
