JConcepts has upped the ante with the release of the new stadium truck, low profile (or LP), hard density closed cell inserts. Black in color, the new inserts are designed in conjunction with insert guru’s Ryan Maifield, Spencer Rivkin, Jason Ruona, and Paul Wynn to bring a firmer touch and feel while providing durability. The stadium truck insert for the (#4049 Smoothie 2) has a smooth exterior for a clean and firm touch-off against the inside carcass on a low profile tire. The inside of the insert 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 high density material providing racers a durable option capable of being used in treaded or slick off-road tires in extremely high-traction conditions.

Features:

• Firm density material and construction

• Low profile (LP) size, shape, and profile, fits JC #4049 tire

• Precise contoured manufacturing
