Product Description
Industrial Injection PDM-24VRH Dodge 5.9L Cummins 24V Race Head (1998.5–2002)
Build the top end your 24-valve Cummins deserves. The Industrial Injection PDM-24VRH is a fully CNC-ported race cylinder head engineered for high boost, high RPM abuse. Ideal for race, sled pull, and serious competition trucks, this head is designed to deliver repeatable airflow, sealing under extreme cylinder pressure, and long-term durability.
Why This Race Head
- Fully CNC Ported intake and exhaust runners for consistent, high-flow performance across all cylinders.
- Surface finish prepared to suit premium gaskets (MLS or fire-ring setups) for reliable sealing at big boost levels.
- Assembled with new valve seals and performance valve springs; ready to bolt on.
- Competition-focused design for 1998.5–2002 Dodge Ram 2500/3500 with 5.9L Cummins 24-valve.
Fitment
1998.5–2002 Dodge Ram 2500/3500, 5.9L Cummins 24V (ISB). Verify piston protrusion and head gasket thickness during assembly for optimal results.
Recommended Parts (CPP Diesel)
- ARP Head Studs (98.5–02 24V) — critical for clamping with MLS/fire-ring gaskets.
- Fire Ring Head Gasket Set (24V) — for extreme boost sealing.
- Heavy-Duty Pushrods (24V) — added valvetrain stability.
- Performance Valve Springs (24V) — control at high RPM/boost.
- High-Flow Intake Manifold (24V) — maximize CNC-ported airflow.
- Performance Exhaust Manifold (24V) — improve drive pressure and spool.
- Matched Injectors (98.5–02) — fuel to match the airflow.
FAQ
Q: Is machine work required before install?
A: This head arrives assembled with new valve seals and performance springs. Always check surface finish, piston protrusion, and choose the correct gasket thickness for your build. MLS or fire-ring setups are typical for high-boost builds.
Q: Do I need head studs?
A: Yes. We strongly recommend ARP head studs for any performance build using this head.
Q: Will this fit my 12-valve (1989–1998) or common-rail (2003–2007) engine?
A: No. This model is for the 1998.5–2002 24-valve ISB only.
