XRAY XLP SPRING-SET PROGRESSIVE C=2.6-2.9 - 308166

The XRAY XLP progressive spring set delivers precise suspension tuning for competitive racing applications. These springs feature a progressive rate design with a C value ranging from 2.6 to 2.9, providing optimal balance between initial compliance and bottoming resistance.

Progressive rate springs compress more easily at the start of their travel, offering excellent mechanical grip over small bumps and surface irregularities. As compression increases, the spring rate firms up to prevent harsh bottoming and maintain consistent chassis attitude through high speed sections and aggressive transitions.

This spring set is engineered specifically for XRAY touring car platforms, manufactured from premium spring steel with precision wound coils. The progressive characteristic allows drivers to run softer initial rates for improved traction while maintaining the support needed for stability under heavy cornering loads and braking forces.

Ideal for medium to high grip surfaces where mechanical grip and predictable handling are priorities. The 2.6 to 2.9 rate range suits a wide variety of track conditions and driving styles, making these springs a versatile choice for both practice sessions and race day setup refinement.
