I'll second that. there identicle to the F1 springs but a lot cheaper, and work great so far.
pm comp461 for a set of springs/retainers
zstroken are they titanium bridges??
Hmmmm, just noticed Hamilton springs are 110 pound seat pressure. Definitely not even close to F1 springs!
Not to hijack, but what kind of rpm will F1 springs support? I'm running them now and will be p-pumping the truck this summer...
Alloyed from Chromium Steel the Pro/SportsMan springs are designed to be used with the Helix 2 and Helix 3 camshafts. They control the valve train without any compromise. They fit in the stock location, use the stock retainers and locks and will not rip the stock valve seals up like a double spring will. They are triple shot peened, and special process hardened to proved a life long solution for the Cummins 24 Valve engine. RPM range is unlimited. Boost is unlimited. You will not float with these. The steel used is an ovate shaped wire, not round. This allows high lift cams to never coil bind and plenty of room to install even the most radical lift lobe camshafts.
