How many miles have u ran them, and who has had them checked to make sure the seat pressure is where its supposed to be? I haven't had any problems with mine, but they have about 15k miles on them now...

Are you referring to the springs that are good to .600 of lift? If so I think I have about 7k on mine and haven't ever checked the seat pressure. Why are you asking, does the manufacture recommend doing that after a certain amount of miles?

Mine have been in over a year now with > 10k miles. My cam has .598" lift on both sides

i have had mine for about 12k and no issues but i mostly baby my truck. i would think the lack of abuse would be a factor in durability.

I would agree. Does anyone on here have some 1218's with 20k + miles?

Crap

I'd like to see a PAC 1218 roll call, including cam specs/lobe design myself. I'm sure that we have members here with 20k + on them, hopefully they'll chime in.

yeah i happin to have some. when i got my motor the guy i got it from had swaped out the springs for the pac1218s bc he was supposed to swap in a cam some time soon. Well he never did and i ended up getting the motor and i dd it every day. I have probably put close to 30,000 on it since i have had it. Havnt had a problem yet. (knock on wood). But i do plan on installing a cam in a couple weeks, just finally got me a lil beat around truck. Might order new ones tho. that is alot of miles on somethhing aftermarket like that.

But im still running the stock lift lq4 cam to. Might not even be stressing the springs with it having low lift i would think. What about yall?
