1. Enhanced Performance: Nitriding is a process that hardens the valve stems and seats, reducing wear and tear and improving engine performance. This can result in smoother operation, improved throttle response, and increased power output.

2. Durability: Nitrided valves are known for their longevity. The nitriding process strengthens the valve material, making it more resistant to corrosion, pitting, and wear. This can extend the life of the valves and reduce the need for frequent replacements.

3. Improved Heat Resistance: Nitrided valves have improved heat resistance compared to untreated valves. This can help prevent valve failure due to overheating, which is a common issue with Harley-Davidson engines.

1. Cost: Nitrided valves are more expensive than untreated valves. The cost of the 18082-57a Shovelhead Panhead 1948-84 Harley Valves Exhaust Nitrided 1948-84 is likely to be higher than that of standard valves.

2. Availability: Nitrided valves may not be as widely available as standard valves. You may need to order them from a specialty parts supplier, which could delay delivery.

If you are looking to improve the performance and longevity of your Harley-Davidson engine, then the 18082-57a Shovelhead Panhead 1948-84 Harley Valves Exhaust Nitrided 1948-84 is a worthwhile investment. The improved heat resistance, durability, and performance offered by nitrided valves can help prevent engine failures and improve overall performance.

Details:

This is a brand new set of 2 standard size diameter black nitride exhaust valves for Harley big twin Panhead and Shovelhead motors from 1948 through some of the model's that may use these valves are shown on the list below. Tech note on black nitride valves black nitride is a hardening treatment that increases the surface hardness of the valve yet it keeps good ductility beneath the hard nitrided layer, unlike stainless valves which are more brittle throughout. The black nitride coating is applied to the whole valve while traditional chrome coating is only applied to the stem.

These valves are marked with the later part number because they are the later nitrided valves rather than plain steel valves. The black nitrided layer is adhered to a valve's base material at a microscopic level, so it can not flake or brake off.

A black nitride surface finish is also smoother than chromed valve stems resulting in less friction between the valve stem and the guide which reduces galling. This is the best delivered price on these parts on. It also makes the valve last longer with lead free fuels and fuels that contain alcohol.
