Following the completion of Friday and Saturday’s Time Runs and True Street Eliminations, each LSX Truck Showdown driver will be required to select an Index and officially submit it to the LSX Event Coordinator prior to Saturday evenings qualifying session. There will be a single qualifier Saturday evening to establish a qualifying order. In eliminations on Sunday morning a 32 or less truck field will be laddered on a sportsman ladder. A 33 or greater truck field is randomly paired until the field reaches 32 vehicles or less. When the field reaches 32 vehicles or less a sportsman ladder for the number of vehicles remaining will be used to pair the vehicles.Vehicle placement on the ladder will be determined based on closest to index (without breaking out) for the last round that was randomly paired.
