The Hamilton Cams 07-S-002 Competition Dual Valve Springs are the perfect option for your high performance 1989-1998 Dodge 5.9L Diesel. 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.
Features:
- 5,000+ RPM
- Competition Use Only
