RC racers wanting tighter control will appreciate the XRAY 368482 Rear Big Bore Conical Spring Set made for the XB2 series. These springs are paired and measured to ensure equal length and matching damping, helping you keep predictable balance and traction during laps.
Each spring is marked with laser-engraved stripes that show firmness, so you can quickly pick the right rate for track conditions. At 57.5mm with a two-dot firmness code, these springs are intended to refine rear suspension behaviour without sacrificing durability.
