The XRay ULP Aluminium Progressive Shock System (XR308029) is an innovative upgrade for ULP touring car shocks, tuned to deliver improved traction and sharper steering on asphalt. Supplied as a set of two, it replaces hole-based damping with a precision insert to create a true progressive response.

How It Works

A CNC-machined insert with three triangular cuts is installed with the wider face at the bottom of the shock and the narrower face at the top. Used together with a piston without holes, damping is controlled by the insert rather than piston orifices. The result is softer damping at the start of travel for grip and compliance, firming up progressively as the piston moves higher in the body.

Materials & Build

Inserts are crafted from premium Swiss 7075-T6 aluminium with a durable black coating. Pistons are moulded using specialised composites, then precisely ground for roundness, stiffness and durability.

Usage Notes

  • Use with pistons without holes.
  • Install on both front and rear shocks.
  • For asphalt use only.
  • Use the same oil as with standard shocks.
  • Suggested compatibility: XRay ULP touring car shocks.

Innovative progressive shock system for ULP touring car shocks for improved traction and steering characteristics. Shock insert has 3 triangle cuts and is used with piston without holes. The hardness of the shock is influenced not by the holes in the piston but with the insert. The insert is mounted into the shock with wider surface on the bottom of the shock and narrower on the top.When the piston is at the bottom of the shock, it moves softer and dampening becomes harder when the piston is going to the top. This means that the shock dampening is softer in the first part of movement and becomes harder when the car is moving more. The shock inserts must always be used with pistons without holes, must be used both front & rear, and only on asphalt. The same oil is used in these insert-equipped shocks as with standard shocks. The inserts are CNC-machined from premium Swiss 7075 T6 aluminum, and are black coated. The pistons are molded using special processes & composites to ensure roundness, while maintaining maximum stiffness and durability. The pistons are additionally precisely grinded.
