The XRAY 308039 Aluminum Progressive Shock System enhances steering feel and traction on asphalt for the XRAY T4 2017. Its progressive behaviour helps maintain balance through mid-corner transitions and exit traction.
Each insert features three triangular cuts that alter flow characteristics while working with solid pistons that have no holes. This produces a gentle initial response that firms progressively as the shaft moves, allowing more predictable handling on smooth surfaces.
Inserts are CNC machined from Swiss 7075 T6 aluminium and given a protective black surface. Pistons are produced from engineered composite materials and are ground precisely to retain concentricity and stiffness for repeatable damping.
A good upgrade for drivers seeking finer damping control on asphalt, this unit improves the XRAY T4 2017 handling without major setup changes.
