DLC Coated trunnions are now available for your 1998-2020 Cummins.Â
These trunnions feature improved oiling to help keep an oil film between the trunnion and the rocker arm as well as DLC coating for additional protection.
Other companies relying on Nitriding are trusting sub-standard surface treatments. Go with the best trunnion at a lower price than the competition.
Pictured above is our trunnion with comparison shots of OEM pieces with wear.
