A linear actuator extension assembly having a base housing, a driving member and a driven member having a housing. The driving member has a driving surface and a threaded lead screw disposed within the base housing. The driving surface is rotated about a first axis to actuate the threaded lead screw, thereby rotating the threaded lead screw about a second axis substantially orthogonal to the first axis. The rotation of the threaded lead screw translates the driven member housing relative to the base housing.
