MELLING AUTOMOTIVE PROD MRM-1731 Features:

Made In USA. The rocker arm ball (aka pivot and or fulcrum) is essential to dependable rocker arm performance. Damaged and / or worn rocker arm balls will increase friction and allow for erratic and inefficient arm movement leading to premature engine failure. A new Melling ball provides a proper base for accurate valve train adjustment. Melling rocker arm balls are manufactured to high quality and material standards. Melling recommends new rocker arm balls with every engine rebuild.
