Yeah I was wondering how many miles aprox. will the prc dual springs last with the ms3 cam? Thanks.

 

i hear 15-20 thousand miles.

I will change mine every 20 thousand in the ms4.. but I drive 1500 miles a year lol.

 

Better check them at 12-15k... the LSK lobes will beat up on a spring far worse than the XE-R lobes on the MS3.

 

thanks for the heads up.

every 12 it is!

 

Do you even know how an LSK lobe works? This is false.

 

On high lift cams, checking pressures every 12>15K is regular maintenance. How long they last is nothing but a guess. I know of some poeple running LSK on setups with over 30K miles. That doesn't mean they all last that long.
If you want long spring life, then proper install at specs and the way you drive them will be a factor.
