The HK-003™ is a billet steel replacement rocker hook for the LSM PC-100™ or PC-100SLC™ .

Prior to 2014 our pressure testers had a stamped stainless steel hook. The HK-003™ is an excellent upgrade. It is engineered to provide a more responsive feel, produce less deflection, have more precise attachment to the back of the rocker, and not bend or deform under the higher seat pressures being used on many engines today. Comes with two new screws for attachment.
