JConcepts has upped the ante with the release of the new Dirt-Tech closed cell inserts for their 1/8th truck wheels. Black in color, the new inserts are designed in conjunction with tire insert guru, Brian “Dirt” Kinwald to bring the ultimate touch and feel while providing utmost durability. The 1/8th truck insert has medium sized cuts on the outside which touch off against the tire inner carcass providing a cushy response and feel. The inside has horizontal channels cut in a 360 pattern to soak up the large impacts and help create forward bite and increase acceleration.
The JConcepts design, with custom sculpted features, are blended into the newly developed material providing racers a durable option capable of being used in medium to extremely high-traction conditions. Testing has shown great results when used in these conditions and in popular tires such Hybrids, Stackers and Black Jackets.
