1989-1998 Cummins Performance 150LB Valve Springs (24G801)
Description
150 lb seat-pressure performance valve springs for the 1989-1998 Dodge 5.9L 12V Cummins (and the 3.9L 4BT Cummins industrial engine). The OE springs lose their grip on the valves once boost climbs past ~45 psi or RPM climbs past ~3200 — valve float costs power, throws timing off, and in the worst case lets a valve hit a piston.
These springs are sized to hold the valves shut at 60 psi of boost and 4000 RPM. They're the standard upgrade before pushing more fuel through a 12V or before installing a performance camshaft. Set includes both intake and exhaust springs for a full head.
Features
- 150 lb Seat Pressure
- Holds Valves at 4000 RPM
- Holds Valves at 60 psi Boost
- Includes Intake & Exhaust Valve Springs
- Fits 1989-1998 12V 5.9L Cummins
- Also Fits 3.9L 4BT Cummins (Industrial)
- Part Number: 24G801
Notes
- Required before installing any performance camshaft on a 12V — stock springs don't have enough seat pressure to hold the valves on a hotter lobe profile.
