Billet DLC Coated Cummins 24v Rocker Arm Trunnion

Upgrade the reliability of your Cummins 24v valvetrain with our Billet DLC Coated Rocker Arm Trunnion—engineered to handle high RPM, increased valve spring pressure, and aggressive tuning without compromise.

Factory trunnions are a known weak point, especially in performance or towing applications. This billet replacement eliminates flex and premature wear while the DLC (Diamond-Like Carbon) coating dramatically reduces friction and heat, ensuring smooth operation and long service life under extreme conditions.

Precision-machined for a direct drop-in fit, this trunnion is the perfect solution for both daily-driven trucks and high-horsepower builds where durability matters most.
