Rear Spring Upgrade: XRAY 358280 Progressive Set

The XRAY 358280 Long Progressive Springs are a targeted upgrade to improve rear traction and handling balance. With a medium stiffness and three stripes for quick ID, they are suitable for fitting to the rear of XRAY XB808 and XB9 models.

Controlled Compression for Better Line Holding

These springs start with a forgiving initial rate to increase tyre contact during turn-in, then progress to a firmer rate that supports higher corner speeds and reduced roll. That progressive behaviour helps preserve predictability through a run.

Quality Matched for Even Behaviour

Each spring is measured and matched to its partner so both sides react the same under load. This matching delivers even damping characteristics and helps when setting symmetric suspension geometry.

Specifications

  • Compatibility: XRAY XB808, XB9
  • Position: Rear
  • Stiffness: Medium with 3 stripes
  • Quantity: Set of 2

A straightforward solution for drivers seeking steadier rear behaviour and cleaner corner exits with minimal changes to existing setups.

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.

How do progressive springs affect tyre wear?

Progressive springs can spread loads more evenly through a corner, which may reduce uneven tyre wear compared with very linear springs.

Can I mix these with different front springs?

Yes, mixing rear progressive springs with chosen front springs is common; tune front-to-rear rates to achieve the desired balance.

What maintenance keeps them performing?

Keep springs clean, inspect for nicks, and confirm they remain matched; replace if signs of fatigue appear to retain consistent behaviour.

Do these springs affect rebound tuning?

They can alter damper behaviour slightly, so you may need to adjust rebound and compression to suit the progressive rate for best handling.
