Full race model pistons are custom forged pistons but available off the shelf. These are single ring, high
compression, lightweight pistons which feature a highly efficient dome design that maximizes squish
without compromising performance. Lateral gasports are added to maximize ring seal while a skirt
coating is included to provide additional lubrication, minimizing friction in extreme conditions. The full race
pistons come complete with high performance rings, lightweight pins and locks.
