4Piston Racing is proud to introduce a superior valve spring at a competitive price point. Many of the K-Series valve springs currently on the market were developed so long ago that they did not consider the RPM range and camshaft size of today's Honda K-Series performance engines.

It features their nitriding treatment and Pro Polish to deliver a motorsport grade spring that will withstand rigorous endurance applications. The retainers are a premium Titanium manufactured right here on their Mazak SYNCREX Swiss lathe to tolerances that only this type of premium equipment can achieve. You will be happy with the packaging and presentation, and even happier with the performance and longevity. This is the spring that you will find in 4Piston Racing's highest level endurance race engines.

**4P has had some questions and comments regarding the higher seat pressure of these as opposed to other lower pressure offerings on the market. The whole reason they made this product was because those lower pressure springs are insufficient to control the valve. 4P's higher pressure spring is made to make your valvetrain last LONGER.**

- 16 Pro Polished Dual Valve Springs
- 16 Spring Seat Locators
- 16 Titanium Retainers
You can use any 7 degree valve lock (keeper) with these retainers. OEM, Ferrea, Supertech, or 4P.
