Crazy Crawler LaserFoam Class 1 FT Pro HD10 1.9″ Foam Crawler Tire Insert (4) (4.19″ Tires)

The Crazy Crawler LaserFoam Class 1 FT Pro tire insert system is a modular tire insert option developed for competition and performance focused drivers running 4.19″ tires. The FT Pro system uses three user selectable LaserFoam rings in each tire – and each package includes four foams. The red “Spur Master” is the ring that provides the lateral stability. The Spur Master insert is supported on each side by your choice of “Heavy Duty” or “Basic” rings (purchased separately) that are added to the tire depending on the desired grip and weight of the model.

To finish off the package, choose “Basic” support rings for harder compound tires, lighter trucks under 7 pounds, or when you want maximum traction. Choose “Heavy Duty” support rings for softer compound tires, or heavier rigs that need more support. Additionally, choose from Heavy Duty and Basic in 10mm or 15mm widths as needed to tailor the insert for different tire widths, and fill out the tire perfectly. 

NOTE: Ideally, you want the insert to be slightly narrower than the width of the tire. Mix and match support rings as needed to create the optimal insert for your tire. Example: Combination for a 37mm wide tire:

• 37mm tire minus 2mm sidewall thickness = 35mm
• Heavy Duty 10 (10mm) + Spur-Master (10mm) + Heavy Duty 15 (15mm) = 35mm overall Foam width
• The LaserFoam HD and Basic inserts should not be exposed to moisture for a long period of time.
