All Crower valve springs are wound from super clean, chrome silicone alloy devoid of impurities and chamfered to reduce imperfections and stress risers that could result in breakage. Crower valve springs are engineered for street or race applications and are the best value in the industry. For those with higher aspirations, Crower is pleased to partner with Eibach for the highest quality, race only valve spring available on the market. Drop-in installation, no machine work required.

Crower utilizes Ti-17 titanium material in the manufacturing process of their titanium retainers. Although harder and longer to machine, the Ti-17 is 8-10 points harder on the Rockwell C scale for added retainer life over conventional 6AL4V titanium commonly used by other manufacturers. The result is added longevity and durability. Crower converted to Ti-17 about two years ago and has seen no wear due to excessive mileage or high rpm's. All Crower retainers are made in-house at Crower using the latest CNC machines to insure quality and batch to batch consistency. A typical Crower titanium retainer weighs about 50% less than it's stock steel counterpart.
