specs are .561 .570 im looking to get pac1218 but seen some others with .650 lft for a lil cheaper. should i just run the pac1218?

 

Very highly regarded spring. My cam has right at .600" lift on both sides with PAC 1218s for over 2 years now. No problems. Ideally, I think I should have gone with the 1518s but SPDC didn't have them at the time. I was told the 1218s are good for .610" lift max.

 

why highly regarded

 

I went with comp 918 springs, picked em up for just over $100 max lift for springs is .625 and lift on my cam is .581- .594 haven't had any problems
