Got my PRC duals in awhile ago, about to do my ms3 install this weekend...



Can't help but wonder- have any of you had binding problems with them? It seems like the 2 springs could possibly bind on one another. Or am I just over worrying?

Any spring can bind with too much lift. Where the springs installed at the correct install height? What is the lift on the cam? What's max lift on the springs?

Anything can break if setup wrong.

Like I said in the first post,

Ms3 cam... .609 lift. Not installed yet..

I was just making a general inquiry as to if anyone has had the small inner valve spring bind on the larger outer valvespring, in a dual spring setup.

Just curious.

Like I said.

If you have the right spring, setup correctly then it shouldn't bind.

You also didn't mention the lift in your first post or what PRC springs you had.

Never heard of that without the inner one breaking.

Wouldn't the inner and outer spring be designed for the same amount of lift? What's the point of an outer spring that's good till .650 and an inner spring that goes to .600?

I guess I don't understand the question.

Yes they are designed for the same lift. He wants to know if they have ever interfered or "gotten in the way" of each other.

Ive ran prc on several engines, Ranging from turbo 6.0s to .619 lift cams. No problems ever.

Did I read it wrong the first time or was the question rephrased?

If I'm not mistaken, they are coiled in opposite directions and therefore can not bind each other (UNLESS one breaks)...

dude yes i did... I said I had the MS3 (really popular cam figure'd ppl would know.. but irrelevant to the question anyway which was specifically about the springs)

I also said I had Prc Duals.. which was the title of the thread.


So yes.. I did say both of those things...

guess I should have said .650 lift duals??

Still, irrelevant though, because All i'm inquiring about is if people have ever had

PRC DUALS (brand specific) bind upon themselves.


Let me "rephrase it"..


Have the 2 springs ever bound on each other and caused issues ?

Pro_built7

iTrader: (9)

Yes. exactly.

Good to hear.

I honestly don't know how to rephrase it any easier.

2 springs in a dual spring right....

can the inner spring bind on the outer spring causing breakage...


I didn't rephrase anything

Ive run the PRC duals on several setups without problems, 7000rpm on a cam with .629 lift to a 5.3 turbo setup pushing 20psi...

prc duals here on a trex 608/614 lift.no coil bind.

They are designed to work together. There should not be any problems with the springs interfering with each other.

Like they said, the springs wind in opposite directions and cannot bind on each other. It is a tight enough fit that sometimes they'll feel like they won't move in and out when pushing them by hand, but that's a much different force/pressure than when installed and running too. You should be good to go with the MS3, no worries!
