Refine Rear Balance with XRAY 358281 Progressive Springs

For hobbyists chasing tighter handling, the XRAY 358281 long progressive springs are tailored for the rear of XB808, XB9, XB8 and XT9 cars. They are engineered to improve corner stability while remaining predictable under load.

Medium-Hard Feel That Steps Up With Compression

These springs are marked with four stripes so you can identify them quickly. Their progressive profile starts at a medium-hard feel and increases stiffness as the spring compresses, which helps the car resist roll and stay composed through fast corners.

Consistent Matching for Track Reliability

Each spring pair is carefully inspected and matched to ensure the same damping on both sides. This matching process reduces setup guesswork and helps drivers dial in suspension settings with confidence.

Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Can I mix these springs with different front springs?

Yes. Tuning front and rear spring combinations is common practice. These are rear-specific, so pick a front spring that balances overall handling for your driving style.

How should I identify the medium-hard version?

The medium-hard long springs are identified by four stripes printed on the coils. That marking distinguishes them from softer or harder variants.

Do these springs need break-in?

No special break-in is required, but it is good practice to inspect springs after a few runs to confirm they remain free of nicks and that preload is correct.
