Hamilton Cams Competition (Up to 6,500 RPM) Valve Springs - 89-98 Cummins 5.9L 12V - 07-S-002

Hamilton Cams Competition Dual Valve Springs
Fits: 1989-1998 Dodge 5.9L Cummins (5,000+ RPM)

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 steam seals or your head must be cut for smaller seals.

Features:

• 5,000+ RPM
• Competition Use Only
