Norris Titanium Valve Spring Retainers - MADE IN USA
Proven facts: A ligher valve train provides higher revs, allows lower spring pressures, gives better horsepower, and results in less wear. If you want the very best in strength and the lightest valvetrain possible, our CNC-machined valve spring retainers are the best in the business. They are tested to over 9000 RPM's and will stand up to the most grueling of applications. They're thicker than our competitors, fit better, and are precision-tapered to provide a superior grip. You'll feel the difference immediately as you're installing them.
These are simply the best titanium retainers on the market, made right here in the USA.
Coupled with our SUPER DUTY aluminum pushrods, 75 gram lifters, and HD valve springs these are the cat's meow for performance applications.
