The Crazy Crawler LaserFoam Class 1 FT ProHD 1.9 Crawler Tire Insert Starter Set is a modular tire insert option developed for competition and performance focused drivers running 37mm wide, 4.19" tires. The FT Pro system uses three user selectable LaserFoam rings in each tire. The red "Spur Master" is the ring that provides the lateral stability, with 10mm and 15mm open cell rings on each side to fill out the tire.
The "HD" set is recommended for softer tires, and heavier rigs that need more support. Each package includes 10mm and 15mm widths. The 15mm wide insert can be added to the inside or outside position to suit the needs of the vehicle.
NOTE: The LaserFoam HD and Basic inserts should not be exposed to moisture for a long period of time.
