Manton is proud to present a premium valve spring assembly for the 6.6L Duramax engine platforms. This valve spring systemhas been engineered to work in unison with all of its included components to provide the most overall valvetrain stability. Our

complete kit will include valve springs, Billet steel retainers, Chromoly spring cups, and valve locks to give you everything youneed to upgrade the cylinder heads valve spring assembly.


When we engineered this spring package we made sure we designed everything with the capability to be used in applications from stock rebuilds, to all-out purpose-built race trucks. When the engineering team was approaching this project, we evaluated what we felt needed to be addressed in order to create a true performance, race quality spring package. We came up with higher boost capability, improved spring shape, and increased rpm capability. We started with the spring shape and used a design that would allow for maximum spring stability at high rpm, while also having a much lower amount of stress the wire will have to live with. This in turn increases service life even in low rpm applications. We have increased the valve spring seatpressure to 130 lbs to retain control of the valves to a higher PSI of boost. Our package will require the use of our lightweight Billet steel retainers that have been designed to mate perfectly with our conical spring shape. This retainer is much lighter in weight and stronger than the OEM retainer because of its reduction in size. Also being included are valve locks to pair with these new retainers.


All in all, we have set out to provide a spring package that will provide the most capability while still remaining a completely drop
in upgrade.
