Hamilton Cams Competition Dual Valve Springs
1989-1998 5.9L Cummins 12V
The Hamilton Cams 07-S-002 Competition Dual Valve Springs are the perfect option for your high-performance 1989-1998 Dodge 5.9L Cummins. There comes a point as rpm, lift, and spring pressures increase, that a single spring is no longer up to the task of controlling the valves. This is when it is time to use a dual spring. Our springs are made in the USA. They come with Retainers and 10-degree locks. These will need to be run without stem seals or your head must be cut for smaller seals.
- 5,000+ RPM
