XRAY 308039 Progressive Aluminum Shock Kit for T4 Touring Cars  [XR-308039]

Precision Dampers for XRAY T4 2017

The XRAY 308039 Aluminum Progressive Shock System is built to sharpen handling and traction on asphalt for the XRAY T4 2017 touring car. The design focuses on progressive damping to improve front and rear balance during aggressive cornering.

Progressive Insert Mechanics

The shock inserts use three triangular slots that interact with pistons that have no holes, creating a damping curve that starts soft and becomes firmer as the piston travels upward. Adjustment of the insert position changes initial compliance and mid-stroke support for finer on-track tuning.

Materials and Finish

Key parts are CNC machined from Swiss 7075 T6 aluminium and finished in a hard black coating for wear resistance. Pistons are molded from reinforced composites, then ground to ensure roundness and consistent stiffness for reliable damping performance.

For racers and hobbyists focusing on asphalt setups, this shock system gives measurable control improvements for the XRAY T4 2017 without complex alterations.
