Yokomo YOKBM206 Shock End 4 / Ball Cup 12 Kit  [YOKBM206]

Damper end parts overview

Included are ball cup 12, shock end 4, plus two rod end offset pieces intended as direct replacements and tuning options for R/C shock assemblies. Labelled sizing corresponds with common ball-cup linkage designs and supports scale R/C fitment.

Replace these parts when worn ends lead to slack in the linkage or when minor changes to shock alignment are desired. The supplied offsets let you move the linkage pivot point slightly to refine suspension feel without major component swaps.

Fitting is simple: remove the existing end, preserve any spacers or washers, and fit the new item making sure the joint pivots freely. Work the suspension through its travel to check for binding and correct any misalignment.

These items are intended for upkeep and small setup changes rather than as a standalone high performance upgrade. They suit hobbyists doing routine shock service and incremental tuning.
