Performance Springs Behive Valve Spring Kit 95lb. Seat, .500" Lift - PSBH103-24

Performance Springs valve springs and valve spring retainer products are manufactured to a strict quality standard to ensure that you get the best for yourdollar. Performance Springs valve springs come to you already scragged to save you time (scragging is a process where the spring is compressedto solid before checking loads). Springs are scragged individually to ensure each spring is to solid height before checking, unlike most that are scragged to a height somewhere close to solid.

Spring wire is also double eddy current tested to a depth of 40 microns and any wire detected with flaws is sprayed, the coiling machine picks this up and rejects these sections. These valve springs are also rattle tested on a specially designed machine which Performance Springs can put a cam lobe into and run a complete set up (lifter, spring, retainer, push rod, rocker and valve) and check for harmonics. Add to all this, the fact that our valve springs are also designed on SRAMA, a computer program fromthe Institute of Spring Technologies which gives stress and pound loadings frominstalled height to coil bind.
