The Yokomo YX-22L rear roll shock mount is an aluminum, left-side bracket produced for competitive 1/12 YR-X12 chassis. It fastens the roll damper to the rear of the chassis and sets the geometry point used when tuning roll stiffness and balance.
When fitted, the YX-22L replaces the factory left mount and uses the same screw and boss locations on both YR-X12 and YR-X1219 variants. Take care to check the seating and alignment during refit to ensure the damper clears nearby components and moves cleanly.
From a durability perspective, this aluminum mount gives a solid platform that resists deformation under load, making it a common service or upgrade item for teams chasing consistent roll behaviour and improved lap-to-lap repeatability.
