Yes, there's a bushing (not really a spacer) made of FRP. It fits around the cast-in sleeve on the LCA and holds the helper spring in place.
It keeps the helper spring from grinding its way out through the bottom of the LCA.
The helper spring handles any misalignments (when the rear suspension is at full droop) between the main spring and the LCA spring seat, allowing the main spring to stay straight below the adjuster.
