Tremors is a wooden roller coaster located at Silverwood Theme Park. It features four underground tunnels, the first of which goes under the ride's gift shop.In 2010, the ride was the first to receive "topper track," a new track system designed by Rocky Mountain Construction of Hayden, Idaho. The new system, similar to the company's new Iron Horse I-Box track system is designed to cut down on track maintenance, as well as daily wear and tear. Rocky Mountain Construction had previously assisted with the initial construction of the ride.
