What is the main benefit of using titanium retainers?

Titanium retainers are significantly lighter than steel ones. This reduced mass helps decrease valve float at higher engine speeds, allowing for more consistent performance when the engine is revved hard.

Are these retainers compatible with stock valve springs?

These retainers are designed to work with specific valve springs for K20A and K20Z engines. It's recommended to consult Manley Performance's technical specifications or your engine build plan to confirm compatibility with your chosen valve springs.

What vehicles does this set fit?

This 16-piece set of Manley titanium retainers is designed for the 2006-2011 Honda Civic and the 2002-2006 Acura RSX, specifically when equipped with the K20A or K20Z engine.

About this part

Product Details

If you're rebuilding the top end of your 2006-2011 Honda Civic, especially for a performance build involving the K20A or K20Z engine, you'll want to pay close attention to the valve train components. These Manley titanium retainers are designed to work with your valve springs, holding them securely in place under demanding conditions. Titanium is a strong, lightweight material that can handle the heat and stress found in a high-revving engine, helping to ensure reliable operation.

Manley Performance is known for making well-built engine parts, and these retainers are no exception. They are made from titanium, which is significantly lighter than steel retainers. This reduced mass at the top of the valve stem helps to decrease valve float at higher RPMs, allowing your engine to rev more freely and consistently. This set includes 16 pieces, enough for a complete 4-cylinder engine build.
