XRay Coil Shock Springs Set of 2 XR372175

The XRay SPRING 4.25 COILS 3.6x7.0x0.4MM C 1.1 - BLACK (SOFT) (2), part number XR372175, is a set of two black coil shock springs with a soft C=1.1 rate. These springs are intended for fine-tuning suspension response, with the softer rate supporting smoother handling and helping to reduce traction rolling in high-traction conditions.

Suggested compatibility includes pan cars and Formula front suspension applications. The spring rate is controlled by the wire thickness and the number of coils: softer springs have a lower C value, while stiffer springs have a higher C value. This gives you a straightforward way to compare spring options when adjusting the handling of a suitable model.

The springs are powder colour-coded for identification, with the black finish indicating this soft option. Their 4.25-coil design and stated dimensions provide the relevant details for comparing them with other XRay suspension springs. They are supplied as a pair for use when matching the spring choice across an axle or keeping a spare available during setup changes.
