Performance Springs PSBH518 LS1/2 Beehive Spring Nitrided Ps Bh518

Performance Springs valve springs and valve spring retainer products are manufactured to a strict quality standard to ensure that you get the best for your dollar. Performance Springs valve springs come to you already scragged to save you time (scragging is a process where the spring is compressed to 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 from the Institute of Spring Technologies which gives stress and pound loadings from installed height to coil bind.
