JConcepts have released the new RM2 hard density closed cell inserts. Black in colour, 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 2wd / 4wd rear insert and 4wd front insert has a smooth exterior for a clean and firm touch-off against the inside carcass on an assortment of tires. 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.
