Yokomo BD-S2W P3 O-Ring Collar (Thin) for BD7/BD5, 4 pcs  [BD-S2W]

Thin O-Ring collar for BD7/BD5

The BD-S2W thin O-ring collar is an RC-scale damper spacer designed to work with BD7 and BD5 compatible large-capacity shock assemblies. Its slim profile positions two O-rings to achieve the intended seal and preload geometry without adding excess stack height, making it useful when a two O-ring setup is required.

The part is supplied as a pack of 4 pcs to cover multiple dampers or spare needs. Installation is straightforward: the collar sits on the shock shaft where the O-rings meet the piston or shock cap, and its role is primarily to set spacing for tuning ride height and initial damper preload rather than to alter damping characteristics.
