This aluminium spacer set is intended for 1/10 scale YZ-2 series models to adjust roll behaviour by lifting the gearbox mount by 2.0mm. The spacer installs under the gearbox and changes weight transfer and roll centre margins without modifying suspension geometry directly.
Fit the spacer under the gearbox, above the rear suspension mount and ahead of the rear brace. Adding this shim alters chassis roll response, which can reduce rear roll and help dial in mid-corner balance depending on other tuning choices such as anti-roll bars and shock settings. Fitting requires basic removal of lower chassis fixings to raise the gearbox and insert the spacer at the mounting interface.
