We are looking forward to seeing participants showcase the performance of their Trucks and SUVs. The rules this year are simple and straight forward. In future events the LS Fest drag race staff will consider additional parameters and rules packages. We look forward to seeing you and your truck or SUV at the race.
This class is a 1/8th mile heads-up small tire class designed for LS or current gen V LT powered vehicles. Engines are allowed the use of a single power adder which is restricted in size to maintain class parity. Come out and see impressive forced induction and/or nitrous powered LS beasts face off!
This is sure to be one of the most entertaining groups of cars on the property! Like every other class at LS Fest, these cars must be LS or Gen V LT powered to compete and are also required to have a clutch assisted “H” pattern shifted transmission. Other than the transmission and clutch restrictions, this class is unlimited! All NHRA speed/time safety rules will apply.
This class has been developed to accommodate the serious LS enthusiast that may not have a class specific build. The performances we will see in this class will be exciting to watch and compete. The class will be full of entries at different power levels but everyone will still have the same ET limit to adjust to. The entry must be LS or LT powered and be able to pass NHRA tech for ET and Speed. For any pair of entries that exceed 5.50 et during eliminations, the closest to 5.50 will be declared the winner as long as both entries left the starting line with green lights. Any run in qualifying that exceeds 5.50 seconds will be placed on the bottom of the ladder. Lane choice will be determined by gentleman’s agreement or coin flips for all elimination rounds.
