Suspension supply is molded from medium hardness composite combination to improve dependability and strength. The medium composite provides exemplary performance on many different conditions because of the added benefit of increased energy. Back suspension system arm accommodates the multi-adjustable uprights. The external pivot of each and every arm utilizes small screws to secure the hinge pins and stop separation in a collision. This floating hinge pin reduces suspension bind. There are three different suspension system hands available: medium, hard and graphite, each appropriate various track conditions.
