Skunk2’s industry-leading Titanium Retainers for Honda’s K-series engines are
designed to significantly reduce valvetrain mass, resulting in more horsepower
and improved valvetrain stability. Unlink other retainers, Skunk2 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.
All Skunk2 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 are
free from machining defects to ensure proper installed valve spring heights and
pressures. Finally, each Titanium 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.
Although retainers may appear easy to make, they remain a critical engine
component where quality control is crucial. Material flaws and improper
machining can result in incorrect valve spring installed heights and potential
retainer failures. Skunk2 cautions enthusiasts from using retainers made from
companies that claim to have engineering capabilities but do not have practical
engine building, CAD modeling, and machining experience.
Note:
- 42
percent lighter than OEM steel retainers.
- Pair with Tuner Series or Pro
Series Valve Springs for the ultimate valvetrain.
Please note: When using
Skunk2 Titanium Retainers (P/N 308-05-0410 or 308-05-1410) on 2004 and newer
engines, pre-2004 keepers (cotters) must be used (Honda P/N 14781-PR7-A01).
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). For
applications where 2004 and newer keepers are used, Skunk2 Titanium Retainers
(P/N 308-05-0410 or 308-05-1410) must be used. Proper retainer/keeper selection
is important due to varying angle ratios between earlier and later keeper
designs. Use of improper retainers and/or keepers may result in potential engine
damage.
