Compatible Models

We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.

Compatible equipment / model
Vehicle/engine Selected Dodge Ram 2500/3500 applications with 5.9L Cummins engines using the 3935945/3935946 rocker design

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.
