Xray Progressive Shock System

New from Xray and made for the T4 touring car is the PSS Progressive Shock System. Designed to improve the steering characteristics and traction when running on asphalt tracks the system utilises machined and black anodised 7075-T6 cylinder swith three triangular-shaped milled out sections and specially made blank shock pistons. Different from a standard shock the milled out holes in the cylinder are responsible for the shock oil to pass the pistons and due to the design of the triangles the shocks work in a progressive manner with the damping becoming harder once the shock compresses. The inserts and pistons are designed in a way that PSS equipped shocks use the same oil weight as standard dampers to make setup and setup comparison easier. The Progressive Shock System set contains two inserts and two moulded and precisely ground pistons.
