For many years Victory has produced Ti-17 titanium retainers for all extreme applications. Ti-17 alloy is far more superior than the Ti 64 (6AL4V) material used by the competitors.
There is no alternative to superiority, that's why we recommend Ti-17 for all retainers in 10,000+ RPM engines.
Prices vary per application so call or email for a price for your application or if you are ordering please specify what engine application your are using and what valve diameter as well as valve lock degrees you are using.
