Awesomatix have introduced this AM180EVO SB bellcrank for the A800MMX single bellcrank steering (SB1). This Evo version is equipped with the same bigger bearings as the M5 version to further increase the reliability. Furthermore the height of the AM180EVO is slightly adjusted to avoid contact with P12X at certain setups. With this change, less bumpsteer shims are needed on the steering arm, which reduces the stress on this part. To keep the same bumpsteer value as with AM180M5 use 1,25mm less bumpsteer shims.
