The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.

Hamilton Cams Competition Dual Valve SpringsFits: 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:
