Product Information

Crower is the only manufacturer that 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 used by all other manufacturers. The result is added longevity and durability. Crower converted to Ti-17 some time ago and has seen no wear due to excessive mileage or high rpm's. Next time you're considering a cheaper alternative, ask what material that manufacturer is using and, if they even know their metallurgy, we guarantee that the reply will be 6AL4V...then ask them about Crower's better Ti-17 material. 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 its stock steel counterpart. For example, the stock K20A2 steel retainer weighs a whopping 14 grams, whilst the Crower titanium retainer weighs in at a miniscule 7 grams. For every gram you can reduce from the valve area (valves, retainers, keepers), and you will pick up an average of 35-40 more rpm in valve control. So a 7 gram weight savings is equal to 280 additional rpm's before valve float.
