YZ-2 Gearbox Spacer Set 1.0mm - Z2-302S1 by Yokomo  [Z2-302S1]

Gearbox height changes to tune rear roll balance

This Yokomo Z2-302S1 spacer set is an RC accessory designed to alter the vertical position of the gearbox on YZ-2 chassis to influence rear roll balance. The kit contains 4 pcs of spacers, each 1.0mm thick, intended to sit below the gearbox, above the rear suspension mount, and beneath the front brace to provide coordinated height adjustment without cutting or reshaping existing parts.

Installation is straightforward: add the spacer(s) where indicated under the gearbox and at the listed mount locations to raise the gearbox by 1mm per spacer. Make small, incremental changes since rear roll center and driveline geometry will shift; test with one spacer first and assess handling before stacking more pieces.

Note that changing gearbox height with this set will also shift the relative position of the motor and the shock tower. If you plan to change motor or shock tower position as part of the setup, use the separately sold Z2-304C-2 in combination, and consider fitting a compatible 3G motor mount to maintain correct pinion alignment.
