What is the main benefit of using titanium retainers?

Titanium retainers significantly reduce the mass in your valvetrain. This weight reduction allows the valvetrain to operate more stably at high RPMs and can lead to an increase in horsepower.

Are these retainers compatible with all Honda/Acura engines?

This specific set is designed for Honda/Acura K VTEC engines, and also compatible with B and H VTEC engines. Always check the detailed fitment list to ensure compatibility with your specific vehicle's engine.

Does this set include everything needed for installation?

Product Details

Starting with medical-grade titanium that's been ultrasonically inspected and certified is how Skunk2 builds its Alpha Series retainers. This material choice is key to significantly reducing the mass in your valvetrain, which translates directly into more horsepower and better stability at higher RPMs. These retainers are designed for a range of Honda and Acura vehicles, including popular models like the Civic, Accord, and RSX.

Skunk2 uses advanced 3D CAD and FEA to optimize each retainer for both strength and weight savings. You'll find radius-cut edges for extra rocker arm clearance and strategically placed lightening grooves. The reduced overall height also helps with valve seal clearance. Each retainer is meticulously machined and inspected to ensure the correct hole diameter, taper, and spring heights, all critical for proper valve spring pressures.

Because these are a performance-oriented component, they're tested extensively on the dyno and even on the race track, pushing engines to 11,000 RPM. This rigorous testing ensures the reliability and performance gains you expect from Skunk2 Racing. You'll want to refer to the manufacturer's installation instructions for specific details on fitting these to your B or H VTEC engine.
