Product Overview
These retainers secure the rocker socket/ball interface so the rocker assembly stays correctly located during valve operation. Cracked, brittle or missing retainers can allow unwanted movement and should be replaced during rocker or cylinder-head service.
The set quantity of 12 is appropriate for common 6-cylinder Cummins rocker arrangements using two rocker positions per cylinder. Confirm your engine generation and rocker design because the 5.9L platform changed substantially across production years.
