Designed for big bore shocks, the XRAY 368273 Rear Progressive Spring Set helps improve traction and control in corners. The dual springs adapt to load changes so the rear end stays predictable through transitions.
These springs compress progressively, offering a softer feel at initial travel to increase bite then firming up as the chassis compresses to keep speed and prevent roll-oversteer. That progressive curve suits drivers who adjust setups frequently.
Springs are measured and matched to ensure identical performance across the pair. Consistent pairing reduces side-to-side imbalance and helps maintain setup consistency across race days.
