XRAY Progressive Springs for Rear Stability

The XRAY 338281 Progressive Spring Set is aimed at improving rear stability by providing a progressive rate from 3.7 to 4.7. This allows the rear to soak small bumps while becoming firmer under heavier cornering loads, helping the chassis stay composed.

Precision Matching for Even Performance

Springs are measured and matched so each pair shows the same compression behaviour. XRAYs quality checks focus on uniformity to ensure you get consistent feel and repeatable tuning results session after session.

Functional Finish and Laser ID

The pearl-grey coating combined with laser-engraved rate markings makes it simple to pick the right springs at the bench. The markings help avoid setup errors when swapping components trackside.
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.

Will these affect corner entry or exit?

Expect improved control during entry due to the progressive soak, and firmer support on exit under power. Adjust front rates to refine understeer or oversteer tendencies.

What maintenance do they need after racing?

Wipe clean of dirt and check for nicks or wear on the coating. Confirm the laser marking remains legible and replace springs if you notice uneven deformation.

Can these be used with aftermarket dampers?

Yes, they are compatible with most rear shock assemblies that accept standard progressive springs. Verify internal diameters and spring seat dimensions for a clean fit.

How do I choose preload with these springs?

Use minimal preload to start so the progressive action is effective; increase in small increments while evaluating handling to avoid masking the spring curve.
