revmax 478-501b, billet 300m intermediate shaft, 47rh 47re 48re billet shaft, dodge cummins transmission shaft upgrade, heavy duty intermediate shaft 5.9 cummins, performance transmission hard parts

The factory intermediate shaft is one of the known weak points in high-horsepower 47RH, 47RE, and 48RE builds. The REVMAX 478-501B Billet 300M Intermediate Shaft is engineered for serious diesel power—whether you're towing heavy, running compounds, or pushing elevated torque levels through your Cummins.

Manufactured from high-strength 300M billet steel, this shaft dramatically increases torsional strength and fatigue resistance compared to stock components. It’s a critical upgrade for performance transmission builds where reliability under load is non-negotiable.

Key Benefits:

• Precision-machined from premium 300M billet material
• Significantly stronger than OEM intermediate shafts
• Ideal for high-torque street, towing, and competition builds
• Designed for performance 47RH / 47RE / 48RE applications

Fitment:

• 1996–1998 Dodge Ram 2500/3500 – 5.9L Cummins – 47RH
• 1996–2002 Dodge Ram 2500/3500 – 5.9L Cummins – 47RE
• 2003–2007 Dodge Ram 2500/3500 – 5.9L Cummins – 48RE

Recommended for performance rebuilds and upgraded clutch/valve body builds where intermediate shaft integrity is critical.

FAQ

High-horsepower Cummins builds can twist or fail factory shafts. A 300M billet shaft dramatically increases strength and reliability under heavy torque loads.

For stock applications, it is not typically required. It is highly recommended for performance builds, heavy towing, or trucks exceeding factory torque levels.

Yes. This shaft is designed for 47RH, 47RE, and 48RE transmissions in 1996–2007 Dodge Ram 5.9L Cummins applications.

Yes. Installation requires full transmission disassembly and proper measurement. Professional installation is strongly recommended.
