Power Driven is proud to announce we are now offering "Bolt On" Tool-Steel Roller Rocker Arm Assembly for 1998.5-2017 5.9L/6.7L Cummins diesel trucks. The rocker arms incorporate Proven Top Fuel and Blown Alcohol Fat Head Hemi Roller Rocker Arm Technology into our diesel rocker arms. Our rocker arm bodies feature a polished bronze bushing. These bodies are machined from proprietary-grade tool steel for specific characteristics when incorporating the heat treatment regimen.

This rocker arm assembly comes standard with all rocker arm hardware, which will include a full set of tool-steel adjusting screws, tool-steel corrected oiling trunnion bearings, tool-steel i-beam valve bridges, 12-point jam nuts, and 12-point rocker arm retention bolts.
