What brand of dual spring is this? (help identify)
What brand of dual spring is this? (help identify) What Valve Springs are these? (Help Identify)
I bought some heads, they have these dual gold springs on them, they look to be either Patriot Performance Gold or PRC springs. They are made by the same company I know but how am I to distinguish the two sets? Is there something in them that have a diff color? Im going to pull a spring and snap some pics, maybe I can find a local performance parts store who can match em. Any help is appreciated.
I found this info:
Here are pics of mine:
Here are manufacturer pics:
Patriot Gold
PRC
Patriot Extreme Dual Springs (silver inner spring/mine are gold)
So I see there is a diff in the locks, what will be the diff in the 10 degree versus stock valve locks?
Thanks
Mike

well the guy who sold them to me said they were PRC but he said someone told him that, as far as I know, Patriots Gold and PRC are the same company, so maybe the same spring from both company's, just a diff name? I just need to know because 1 was broken and I need to order a new spring.
Thanks for any help.
Thanks for any help.
Unless as stated the two brands are exactly the same, i found a guy here with a great pic, look exactly like mine, the only difference is that my inner spring is also gold, not silver and he says:
Patriot Extreme Dual Springs

Yours are definitely PRC. The Patriots use the larger super 7 locks and PRC re-uses the stockers. If you look at your pic versus the pic in post# 7 you can see the difference in retainer diameter.
