Features & Product Details

This is the GSC Power-Division Single Valve Spring Set and Titanium Retainer Kit which are the result of some of the most advanced manufacturing techniques in the industry.

This provides the spring with the highest level of spring load retention while still maintaining good fatigue for the life of the spring. 

 

FEATURES:

  • Includes 16 cylindrical valve springs
  • Includes 16 titanium retainers that are CNC machined
  • Nano peened and batched according to seat pressure within spec
  • Max RPM: 8,200 RPM
  • Maz boost: 32 psi

    Recommended by my tuner for my EJ257 rebuild 2 years ago

    Installed these in a stage 2-ish Legacy GT during an engine rebuild. I street-drive the car and was recommended these over OEM ones. The car revs quite happily and it's quite smooth in power delivery now. Hard to explain just how much smoother the car feels when getting into any amount of boost, even at low RPMs. Would definitely recommend, even for a stock car. I also used GSC intake and exhaust valves.

    QUESTIONS & ANSWERS

    • Q: Jdm ej205  Ninjor3 years ago

      Hi there I was wondering if this fit a jdm ej205
    • Q: Are these a good suggestion?  biddyhound454335 years ago

      Planning on pulling my motor, and while the heads are out and going the machine shop, I figured upgrading the valve springs to allow for some additional revs would be a good idea. I plan on running a stock VF39 or possibly an EFR 6758 in the future. Would these be a good recommendation with a 7500-8000k rpm redline?

        A:  I would say that while these might do I would spend the extra 100 and do the beehive kit. In all honesty I would recommend contacting your engine builder though in regards to future plans and see what they say!

    • Q: Fitment with shim under bucket style   Lavjerj229427 years ago

      My 2004 Subaru wrx has the shim under bucket style for valve adjustment. Would these be compatible with that?

        A:  These springs and retainers are compatible with all the vehicles in the Confirmed Applications list, including 2004 WRX.
