This Yokomo YX-22L rear roll shock mount is a left-side aluminum bracket crafted for 1/12 YR-X12 competition chassis. It anchors the roll damper to the rear chassis and defines the leverage point used when adjusting roll control and rear-end behaviour.
Installation replaces the stock left mount and utilises the same chassis fixing points on the YR-X12 and YR-X1219 models. During refit, confirm the damper clears the surrounding layout and that all linkages articulate freely through the suspension travel.
As part of setup work the mount influences how damper inputs feed into the rear suspension geometry, so swapping or inspecting the mount is a practical tuning step for drivers seeking crisper turn-in and consistent roll management.
