This is a pack of two JConcepts Dirt-Tech Short Course Closed Cell Tire Inserts. Gray in color, these inserts were developed in conjunction with tire insert guru, Brian “Dirt” Kinwald to deliver incredible performance, while at the same time providing the durability that racers demand.

The SCT insert has deep cuts on the outside which touch off against the tire inner carcass providing a cushy response and feel. The inside diameter of the insert has horizontal channels cut in a 360 pattern to soak up large impacts and help create forward bite and increase acceleration. The custom sculpted JConcepts design has been blended with a unique medium/firm density material to provide racers with a durable option that is an excellent choice for medium to extremely high-traction conditions.   

  • Medium | Firm density material and construction
  • Extremely light-weight
  • Versatile size, shape and profile, fits vast majority of tires
  • Precise contoured manufacturing
  • Durable material, can be reused
  • Gray color for easy identification
