Race valve springs for S63TU from Arsenal Motorsports

[Sticky]

This is a valve spring kit Arsenal is marketing with these claims:

- Conical Race Valve Springs
- 6AI-4V Titanium Retainers
- 33% stiffer & 25% lighter than OEM components
- Uses factory keepers!


Conical Spring Benefits:

Vastly improved harmonic stability with inherent self-dampening design
Smaller design = weight reduction throughout the entire valve train system
Applications for high RPM and boost pressure, more stable at higher cylinder pressure, and back pressure.

State of the art manufacturing and engineering production processes
Titanium retainers is machined smaller diameter to fit Inner top diameter of conical valve spring. which will also reduce weight.

Ultimately, less weight=less wear=reliable=more capable power gain
The S63TU Cylinder head has a small port design from the factory ( which is better for EPA regulations, but not for true power) , and high back-pressure condition from stock form. Our valve springs kit will handle much better in these extreme conditions as well as more boost to come.
