Gravity RC B64 2mm diff shim
Gravity RC have introduced a new optional part for Team Associated’s B64 4WD off-road buggy in the form of a 2mm diff shim. The 3-D-printed part is conventionally used to raise the rear differential of the B64 buggy. The increased height of the diff will result in a more conventional dog bone angle at the desired ride height and will increase grip and overall consistency. The part is especially recommended in the rear, but also applicable for the front.
