Koswork O-Ring 8x1mm for Lower Cap 12mm & 13mm AE RC Shock Part - KOS04809

The Koswork KOS04809 O-Ring set provides 8x1mm replacement seals for the lower shock cap on 12mm and 13mm Associated Electrics shocks. Keeping the lower shock cap properly sealed is essential for consistent damping performance — a worn or damaged O-ring allows shock oil to leak, leading to uneven suspension response and loss of feel on track. This is a direct replacement part for AE-compatible builds running Koswork or Associated shock assemblies.
