XRAY 358280 Long Progressive Springs Medium V2 Rear Performance Set  [XR-358280]

Upgrade Rear Traction with XRAY 358280 Progressive Springs

XRAY 358280 Long Progressive Springs are crafted to refine rear-end behaviour for competitive driving. The medium stiffness and three stripe marks make identification straightforward and they are intended for rear installation on XRAY XB808 and XB9 cars.

Progressive Action for Stable Corners

By offering a softer initial rate that firms up under heavier loads, these springs help the car hold the line entering a corner and then provide the support needed for higher exit speed. The progressive profile supports predictable weight transfer.

Consistent Pairing for Reliable Setup

All springs are individually checked and matched so each pair delivers nearly identical performance. That consistency removes variables when tuning dampers and spring preload for race day.

A practical upgrade to sharpen rear grip and improve corner exit stability without complex chassis changes.
