2023 Sport Modified (Sport Mod) Monster Truck
Rules & Class Information
This class is in the spirit of the first generation of Stage 3 monster trucks that participated in the Penda Series era in the 90’s. This is intended to be a more budget friendly version of the modified class, wherein the trucks are also easier to control due to lower speeds. Vehicles in this class can participate in general freestyle, with Pro Mods.
These rules were decided and voted on by the competition committee and are good for the 2023 Calendar Year. All rules are subject to changes, additions and/or subtractions based on new technology, parts and/or chassis’ at any time and at Trigger King RC’s sole discretion.
All vehicles must have a minimum of 2 solid axles. Motor on Axle (Clod Buster) gearboxes are legal. Shaft driven trucks are legal.

Most scale appearing Clod Buster sized monster truck wheels are legal. Any Losi LMT short-course style wheel/tire is NOT allowed.
