Crazy Crawler LaserFoam "Heavy Duty Class 1" 1.9 Foam Crawler Tire Inserts are precision cut open cell foam tire inserts designed for performance. LaserFoam inserts offer incredible lateral stability and sidewall support, yet still remain nice and soft on the contact patch. The material and cut shape ensure that the tire only rolls in the area of the tread that is in contact with the surface, creating great driving characteristics and an incredibly scale look. Plus, the soft open cell foam material allows the insert to fit even when internal weight is added.

These LaserFoams are RECON G6 Certified, and fit Pit Bull Braven, Proline Hyrax Class 1, and RC4WD Goodyear Wrangler MT / R tires and many other 4.19 size tires. These fit other tires as well, but the foam may require trimming (see fit list below). 

NOTE: The LaserFoam HD inserts should not be exposed to moisture for a long period of time.

101x35mm Class 1 LaserFoams are offered in three types:  

  • Basic: For light trucks (less than 7 pounds)
  • Heavy Duty (HD): For middle weight trucks (7-10 pounds)
  • WP Magic: For heavy trucks (10+ pounds)

Crazy Crawler LaserFoam Heavy Duty 1.9" Foam Crawler Tire Insert (2) (101x35mm)
Awesome foams that fit into my new tires for my Tamiya Toyota Hilux High Lift. Great support.

Crazy Crawler LaserFoam Heavy Duty 1.9" Foam Crawler Tire Insert (2) (101x35mm)
These are installed in a set of ProLine Hyrax Class 1 tires on a truck that weighs 7.5 lbs. The stock foams would let the tires fold under the wheels during harsh sidehill maneuvers. These crazy crawler foams are a huge improvement and offer better support and hold the tires in better shape on jagged edges and steep side hills. I will primarily use my truck for trails and rock crawling.
