Progressive Rear Springs from XRAY

The XRAY 338281 Progressive Spring Set is built to sharpen rear traction and improve stability. These springs use a progressive compression range from 3.7 to 4.7 so the initial travel remains supple while the rate increases under heavier loads, helping maintain balanced handling across mixed surfaces.

Matched Pairs for Predictable Response

Each spring is checked and matched to ensure paired units share the same damping characteristics. XRAY applies careful measurement and inspection so you get consistent behaviour from left to right, which is essential when dialing in chassis balance for competition.

Clear Identification and Robust Finish

The pearl-grey coating and laser engraved markings make it simple to identify the correct springs during setup changes. The finish helps resist wear and keeps your springs easy to sort in a busy pit area.
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 springs fit my existing rear shock bodies?

These springs are intended for rear suspension use and fit standard rear shock assemblies that accept matched internal springs. Check your shock internal diameter to confirm compatibility before fitting.

How should I adjust for different track surfaces?

Start with the softer initial compression for low-grip or bumpy tracks to boost traction, then move toward the firmer part of the range for high-speed sections where roll control is needed. Small incremental changes work best.

Do these springs require special maintenance?

Keep them clean and inspect laser markings periodically. Replace springs if you notice visible wear or if matched characteristics drift after heavy use.
