What is the maximum RPM this valve spring kit can handle?

Manley designs these springs to handle aggressive aftermarket camshafts and high RPM operation, up to 10,000 RPM. This ensures consistent valve control under demanding conditions.

Does this kit include everything needed for installation?

This kit includes 16 valve springs and 16 titanium retainers. However, the valve locks are not included, so you will need to source those separately.

What is the benefit of titanium retainers?

The titanium retainers in this kit are heat-treated and CNC machined to precise specifications. This contributes to the overall stability and reliability of the valvetrain at high engine speeds.

About this part

Product Details

If you're pushing your 2003-2005 Dodge Neon's engine hard, especially with aftermarket camshafts, you need valve springs that can keep up. This kit from Manley Performance is built to handle the demands of high-RPM operation and aggressive cams, ensuring your valvetrain stays stable and controlled when you need it most.

These springs are made from a chrome-silicon alloy, which offers strong fatigue resistance and high tensile strength. This means they'll consistently control the valves even at extreme engine speeds, preventing issues like valve float. The kit includes titanium retainers that are CNC machined for precision, and the springs themselves are designed to work with aftermarket camshafts, giving you the confidence to rev your engine higher.

This kit includes 16 springs and 16 titanium retainers, but note that the valve locks are not included. Make sure you have these on hand before you begin installation.
