Fixing to install f13 cam and prc spring kit and was wondering how many miles i can put on these springs with the f13 cam before they'll need to be replaced?thanks

 

I'd say near 20-30k

 

We have customers with 20k plus using our Patriot Gold spring. Other "gold" springs have not been on the market long enough to get this type of mileage on them.

 

When putting aftermarket springs, one should do a yearly maintenance and measure the springs.
Now as it has been said many times before, this does not mean you'll change them, but it will give you an idea if anything is going wrong (weakening springs)
this should be done just like changing oil etc.....
Call it mod maintenance.

 

Sound advice.

 

what do you check for and how do you do it...specifically...thanks

 

You have to have a spring tester, basically a scale that measures how much pressure a spring exerts at different heights.

 

and you can get them where...and how much

 

Summit carries a couple of different ones:

PRO-66774 up to 300lbs
PRO-66775 up to 700lbs

Both are $214.88.

 

why does everything have to be so much money

 

Unlike the "other" gold springs on the market, the PRC springs were tested by PRC prior to taking them to market. The customer was not the guinea pig. Not every company can say that. We also know they work well because we run them on our personal vehicles. We just finished putting together an '01 WS-6 T/A that we recently bought, and we're running a hydraulic-roller camshaft with .640" lift. The difference is having enough faith in the products you sell to run them on your personal vehicles.

always soo much tension... fwiw i am running the prc's and have had no problems in about half a year or so not sure how many miles...but i drive it about 200 a week...so i'd say around 5,000miles

 

heheh...no kiddin' I'm getting tired of this PRC vs PP spring issue...it's freaking childish as hell...

What's not childish is my idea: Let's arrange a romantic dinner for Gunnar and Trevor. That will help them in achieving the truce...

 

no tension here It's just part of defending a product after another vendor goes out of his way to discredit it. We run what we sell, and I think that's worth something to customers to know that a vendor trusts a product enough to run it on their own vehicles.

Somebody is testing out some new springs that are about to be released

 

Its pretty bad when the springs way outlive the heads they are on.

 

that's most likely the funniest thing i have ever heard...

 

A digital bathroom scale on a drill press with an old valve in the chuck as a ram has served me well as a spring tester.

 

To bad you guys sold them.

 

Hmmm who could that be? I thought the Z just sits there and looks pretty now.
