Tune Rear Traction with XRAY 358281 Long Progressive Springs

For racers wanting sharper handling, the XRAY 358281 long progressive springs are engineered for the rear suspension on XB808, XB9, XB8 and XT9 platforms. Built with racing use in mind, they help refine turn-in and mid corner balance.

Progressive Action for Improved Corner Entry

The XRAY 358281 springs feature four identification stripes and a progressive rate that starts with medium firmness and firms up deeper into travel, delivering reliable initial grip and stronger support under heavier compression. This progression stabilises the car as it leans into corners and helps maintain speed through turns.

Matched Pairs for Predictable Handling

Each pair is measured and matched so both springs share the same damping characteristics, reducing variables during setup. That consistency makes suspension tuning more repeatable and gives drivers confidence over multiple runs.

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 these springs be used on the front end?

No. These springs are intended for rear suspension only on the compatible models listed. Using them at the front will change handling in unintended ways.

How do I identify the spring rate?

Look for the four stripes printed on the spring coil; that mark indicates the medium-hard progressive version of this long spring.

Will these work with different shock bodies?

Yes. They are compatible with standard rear shock bodies used on the XB808, XB9, XB8 and XT9, but you may need to tune spring preload and oil weight to match your setup.
