Brand New PERFORMANCE Valve Springs available by SPR Motorsports.
Valve springs and valve spring retainer are manufactured to a strict quality standard to ensure that you get the best quality for your dollar.
All 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). Our 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.
The valve 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.
For quality control, valve springs are also rattle tested on a specially designed machine which we can put a cam lobe into and run a complete set up (lifter, spring, retainer, push rod, rocker and valve) and check for harmonics. Finaly, the valve springs are also designed on SRAMA, a computer program from the Institute of Spring Technologies which gives us all stress and pound loadings from installed height to coil bind.
All our valve springs are chrome silicone and our retainers are all 4140 moly.
