Certain aspects of the present disclosure provide a ramp for a hard disk drive. The HDD ramp generally includes a ramp body having a head separator fin, a gimbal limiter adjacent to the head separator fin which is thicker than the head separator fin, and a first chamfer at a transition between a first surface of the gimbal limiter and a first surface of the head separator fin. A hard disk drive including such a HDD ramp and a method for using the HDD ramp are also disclosed.
