UPDATED 10/1/2019: "WHAT IS TUFF TRUCK RACING" VIDEO ADDED TO THE FRONT PAGE AND A NEW OCTOBER VIDEO OF THE MONTH
WELCOME TO

Tuff Truck Racing is a form of Off-Road racing that is usually broken down into different classes such as:
STOCK
MODIFIED
2WD STOCK
4WD STOCK
Every event has a different way of operating as far as what classes they will have but those 4 mentioned above is a good hint.
The ways of racing Tuff Trucks have even more variety. There's time trials, head to head racing (with or without qualifying), fastest total times with multiple runs, call outs for a driver to challenge another driver regardless of class, and even wheel to wheel with multiple vehicles running at once! I seriously don't think I can name all of the ways a race can be ran.
PENALTIES
Penalties during Tuff Truck runs are usually handed out for hitting cones on the course, not having both front wheels hitting a ramp, running the course the wrong way, etc.
Penalties can range from time added to a run to a disqualification.
STOCK CLASS
The Stock class usually consists of vehicles that are taken off of the street mostly because they are unable to pass inspections but people some times will take their daily driver and participate in the event. And yes some times it doesn't end well for that participant.* The Stock class has a little flexibility when it comes to modifications but not too much. You are allowed to use aftermarket suspension parts but most events will limit how much lift you are allowed to use for around 4 to 6 inches whether it's by shocks or springs. For engine modifications you are allowed to do a little work but again nothing too drastic such as a intake, air filter, headers, throttle bodies, or carburetors. The motor, drive line, frame and some times the body structure as well must be exactly how it was offered by the factory. However one thing you are able to do though is mix factory parts for your vehicle. For example certain Jeeps are made with 4 cylinder, 6 cylinder and v8 motors. If you had a Jeep that was currently a 6 cylinder you could take that motor out and give it a v8 as long as it was a v8 that was offered by the factory. The same can be applied to the drive line.
*Here is an example of some one who took their daily driver to run Stock Class Tuff Trucks at the Bloomsburg 4 Wheel Jamboree in Pennsylvania and it did not end well for him.
MODIFIED CLASS
The Modified class has less restrictions but some events will even have no rules restricting the modifications to a vehicle at all so the possibilities are endless. Some of these modifications include King Shocks as well as custom mounting, fiberglass bodies, non factory motors capable of more than 500 horsepower, bigger and reinforced axles, and modifying tire threads.
In this class you can find Ultra4 Cars, Trophy Trucks, Stadium Super Trucks, PreRunners, Baja Bugs and even stock class vehicles entering to try and beat the modifieds WHICH THEY CAN!*
*Here is an example of a Stock Class vehicle beating a HIGHLY modified vehicle. Watch this Stock class Subaru Brat with less than 100 horsepower beat a Modified Class Truck with more than 500 horsepower.
