Make an appointment for Chassis tag tech for UTV Hammers, Every Man Challenge, and Race of Kings.

You will need to have your chassis inspected if it does not have a tag on if from 2022 or newer.

If you have a chassis tag, or are doing the desert race only, you do not need to make an appointment for a chassis inspection. Race tech will be done per the schedule on the website. You will need to have your chassis tagged to pass regular tech inspection during contingency day.
Cars without chassis tags will be failed until they pass chassis inspection.
