XRAY Front Spring for 4mm Pin C=0,9 - Silver (2) XR-372191

The XRAY Front Spring C=0.9 is designed for racers running 4mm pin suspension setups who want precise control over their chassis balance. This silver spring gives you a specific spring rate that works well for fine tuning your front end compliance on different track surfaces. When you need a softer front to help your car rotate better in tight corners or generate more steering on low grip tracks, this is the spring rate that gets you there.

What makes this spring useful is how it lets you dial in exactly the front end feel you're looking for without making drastic changes to your setup. The C=0.9 rate sits in that sweet spot where you get noticeable improvements in corner entry without sacrificing stability on high speed sections. You get two springs in the package, so you can run a matched pair on both sides for consistent handling characteristics.

These springs are built to XRAY's usual standards, which means they'll hold their rate through multiple race weekends without sagging or losing tension. The 4mm pin design works with XRAY's current suspension architecture, making installation quick when you're testing different spring combinations at the track. For racers who are serious about setup and want reliable components that perform the same way every time you bolt them on, these springs deliver exactly what you need to keep your car competitive.
