Introducing the worlds first Billet CNC Machined Valve Covers available to the public!
First on deck for late spring 2019 release - after months of development - the RMZ450 Billet Valve Cover.
- Billet 6061 aluminum which is stronger than OEM magnesium.
- Stiffer material - means we can add to the gasket compression to solve that oil weeping.
- In addition to the stiffer material, the structure was beefed up with ribs extending from the mounting holes to better distribute the bolt loading when compressing the gasket.
wrong with magnesium! Great OEM material choice for inexpensive
mass production. Light and easy to cast. But in this
application - we spent extensive time optimizing the geometry to provide
a stiffer structure within a few grams of being equal in mass to the
OEM cover. A valve cover can benefit from greater stiffness
because it needs to load and compress the rubber gasket.
fact for the day - heat transfer is greater with aluminum. Not a
significant factor on the top of the head but science is science!
up are the YZ250f and RMZ250. Eventually we will get to all of
them! Please feel free to pester us and help us keep the
priorities in the right order.
