Skunk2 is proud to introduce its Alpha Valve Spring and Titanium
Retainer Kit for Honda’s K Series engines. Each kit includes
Skunk2’s high-quality dual valve springs and race-proven titanium
retainers that are the result of nearly two decades of racing and
engine building experience. Each Alpha Valve Spring is
manufactured exclusively from super-clean, chrome-silicone wire
milled in Japan. By using inner and outer springs mated together
through a slight interference fit and with differing frequencies,
Alpha Valve Springs are able to prevent valve float and maintain
valvetrain stability at engine speeds in excess of 10,000 rpm.
Skunk2’s industry-leading Alpha Titanium Retainers are designed
to significantly reduce valvetrain mass, resulting in more
horsepower and improved valvetrain stability. Similar to Skunk2’s
already popular Pro Series Titanium Retainers, Alpha Titanium
Retainers feature radius-cut edges for additional rocker arm
clearance and reduced weight, strategically positioned lightening
grooves, and reduced overall heights for better valve seal
clearance and even further weight reduction. Alpha Titanium
Retainers are manufactured using the latest 3D CAD (Computer
Aided Design) and FEA (Finite Element Analysis) to ensure that
each is optimized for strength as well as for reduced weight.
Skunk2 engineers then test and prove their designs on the engine
dyno as well as the race track. Once approved for manufacturing,
only medical-grade titanium that’s been ultrasonically inspected
and certified is used. Following CNC machining, each retainer is
then individually inspected to ensure proper hole diameter,
taper, and that each piece is free from machining defects to
ensure proper installed valve spring heights and pressures.
Finally, each retainer is serialized for your protection,
including valuable information, like material batch specifics as
well as production and inspection dates. Skunk2 designs,
develops, and tests its entire valvetrain lineup in-house to
ensure superior quality and maximum performance gains. During
development, each valvetrain component is tested both on the dyno
and the road, including 11,000 rpm drag racing engines and 17,000
rpm superbikes. Manufactured from the best materials available,
Skunk2 valvetrain components provide exceptional performance,
reliability, and quality and remain standard-issue on each Skunk2
vehicle that we build and support Features: Retainers engineered
from high quality titanium using 3-D CAD and FEA Springs milled
in Japan from super clean chrome-silicon wire Seat Pressure: 60
lbs at 1.600” Open Pressure: 220 lbs at 1.100” Coil Bind: 1.000”
Note: When using Skunk2 Titanium Retainers on 2004 and newer
engines, pre-2004 locks (keepers/cotters) must be used! Pre-2004
keepers can be identified by the absence of marks along the top
edge (2004 and newer keepers feature laser-etched marks along the
top edge). Proper retainer/lock selection is important due to
varying angle ratios between earlier and later lock designs. Use
of improper retainers and/or locks may result in serious engine
damage. Must Use Skunk2 PN 312-05-0010 (Spring Bases) to Install
