Product Overview
Tier 4 Diesel Rocker Arm 4003905, Vacuum-Remelted Steel & Harmonic Damping Technology for Cummins
Tier 4 Diesel Rocker Arm 4003905, Vacuum-Remelted Steel & Harmonic Damping Technology for Cummins
In the brutal arena of diesel valvetrains—where lesser arms bend or shatter—these rockers are kinetic sculptures of vacuum-remelted 4140 steel. Designed for Cummins M11 engines pushing 500+ hp, they transform camshaft whispers into explosive valve action, surviving 1.5 million cycles without flinching.
Engineering Secrets Unlocked
Harmonic Assassin
Tuned inertia pads absorb 9 kHz valve spring surge (killer of pushrods).
Friction Slayer
Micro-grooved roller paths retain oil films at 150°C—reducing wear 60% vs. OEM.
Overhead Crusher
Forged arch bridge design deflects 0.01mm under 6G vibration—protecting valve tips from mushrooming.
Extreme-Duty Provenance
Australian Road Trains: Endured 800,000 km of Outback corrugations—zero spalling.
Tier 4 Final Rebuilds: Outlasted factory arms by 2x in DPF-regeneration heat cycles.
Arctic Drilling Rigs: Operated flawlessly at -45°C while competitors shattered.
