The BD-S2W P3 thin O-ring collar from Yokomo is a precision damper spacer designed to suit BD7 and BD5 compatible large-capacity shock assemblies. Its compact profile aligns two O-rings to produce the required seal and preload geometry without raising the overall stack height.
Provided as a pack of 4 pcs, the item covers the common need for multiple dampers. Fitting is done by placing the collar on the shock shaft where the O-rings meet the piston or cap; it is intended to set spacing for ride-height and initial preload adjustments rather than to modify damping performance.
