Skunk2 Titanium Retainers B16A2 B18C1 H22A H22A1 H22A4 F20B

Titanium Retainers are light-weight, and very strong. Its a good idea to replace your factory retainers because if one of your OEM retainers breaks after installing a more aggressive cam, it will drop a valve into the engine and completely destroy the entire engine. Also, titanium retainers are lighter, and freeing up mass in the valvetrain will help free up robbed power in the engine.

Automotive Race Engineer and Published Author Herb Adams explains that reducing rotating mass from the assembly moving at engine-speed provides similar gains to removing 15 times its static weight from the chassis. While the retainers are not rotating, they are still a weight-component in an assembly traveling at engine speed. The lighter you can get engine components the better.

Skunk2’s industry-leading Titanium Retainers for Honda’s B-series and H-series VTEC 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.
