6MIK have introduced the new quick change gearbox cover for the HB Racing D819RS, D819 and E819. Suitable for both front and rear gearboxes, the part is3-D–printed by using a high-quality and ultra rigid fibre material resistant to temperatures of up to 180 degrees Celsius. The gearbox replaces the standard part and allows to remove your differential very easily and quickly without removing the lower arms, making it very easy to remove the differential for maintenance or to change the setting.
