The Monster Jam Protectos are designed to fit Spinmaster and some Hot Wheels Monster Trucks, providing protection for your valuable vehicles. The trucks in the pictures are NOT included and are for reference only. They're manufactured by Monster Jam so they do a great job securing the trucks. These new protectos are essential for keeping your diecast trucks in pristine condition. The Hot Wheels trucks with the rounded blister and the long backer trucks don't fit. Some of ther newer Spinmaster trucks don't fit because they glue them on the backer off center, SO Beware! If you have any questions about what they fit just ask us. We have many trucks to test them out on for you. Thanks for looking!
