INSTALLED HEIGHT SHOULD BE CHECKED AND ADJUSTED AS NECESSARY.
These high rev performance silicone chrome valve springs help prevent valve float and improve power in race and street high-performance engines to 8000+ rpm.
Our shop has used these custom manufactured springs in customer performance engines all these years. These VSS12 springs work well at high RPM with both performance and race cams up to 12mm lift.
“I just installed your valve springs. I’m actually very impressed by the quality. I checked them with a Rimac spring tester and managed to pair them into 8 sets with less than 1 lbs. in difference between the sets. Regards.”
