Rev Beyond Factory Limits – Safely
Factory valve springs weren't designed for high-RPM performance. These 60# over-stock valve springs let your 1989-1998 12-valve Cummins safely exceed 3000 RPM without float, bounce, or valve train failure.
What You Get:
- Set of 6 valve springs
- 60 lbs over stock spring pressure
- Direct fit for Dodge Cummins 12v diesel engines (1989-1998)
- Engineered for high-RPM stability and reliability
⚠️ Important: Two sets required for complete engine (12 total)
Why Upgrade?
Stock springs limit your engine's potential. Whether you're running aggressive fueling, compound turbos, or competition builds, these springs provide the valve control you need to keep your engine together under load. No more valve float. No more missed shifts. Just reliable power delivery when you need it most.
Fitment: 1989-1998 Dodge Ram with 5.9L 12-valve Cummins diesel
Note: Professional installation recommended. Valve spring replacement requires cylinder head disassembly.
