The XRAY 308039 Aluminum Progressive Shock System improves traction and steering on asphalt for the XRAY T4 2017. It delivers gradual damping buildup to keep the car composed through corner entry and exit.
Each insert is cut with three triangular slots that interact with holeless pistons to create a staged damping response. Moving the insert changes the initial compliance, allowing drivers to tune responsiveness for different tracks.
Inserts are CNC machined from Swiss 7075 T6 aluminium and finished in a durable black coating. Pistons are molded from advanced composite material and precisely ground to ensure concentricity and long-term stiffness.
An effective upgrade for enthusiasts focused on asphalt performance, this kit helps dial in the XRAY T4 2017 for sharper handling with minimal fuss.
