Optimise Rear Handling with XRAY 358281 Progressive Springs

The XRAY 358281 long progressive springs are developed for rear fitment on XB808, XB9, XB8 and XT9 cars, giving drivers a predictable, rising-rate characteristic that helps with turn-in and exit stability.

Stepped Damping Curve for Corner Stability

These four-striped springs start with a medium-hard response and increase stiffness through travel, supplying initial traction followed by greater support under heavier loads. The stepped damping curve helps the car remain composed during aggressive cornering.

Precision Pairing for Even Response

Every pair is measured and matched to ensure the same damping behaviour on each side, helping to eliminate inconsistencies and allowing drivers to focus on fine tuning spring preload and shock settings.

Are these designed for offroad or onroad use?

They are designed for offroad rear suspension on the listed buggy models, where progressive support helps with jumps and rough corner entries.

Will the four stripes wear off?

The stripe marking is durable, but like any spring, heavy use and abrasive contact can dull the print. Periodic inspection is recommended to confirm identification.

What adjustments complement these springs?

Try altering shock oil weight and piston choice, plus spring preload, to match track grip. These changes work together with the progressive rate to tune balance and response.

How important is matching pairs?

Very important. Matched pairs keep left and right behaviour even, which is crucial for stable handling and predictable lap times.

Can I use these springs with aftermarket shocks?

Yes. They are compatible with many shock setups, but confirm spring length and mounting fitment before installing to ensure correct geometry and travel.
