Supertech Nissan Patrol TB48DE Black Nitrided Exhaust Valve - Set of 12

If you're rebuilding the top end of your Nissan Patrol with the TB48DE engine, these black nitrided exhaust valves from Supertech are a solid option. This set includes 12 valves, enough to replace all the exhaust valves in your engine. They're made to handle the demands of a performance-oriented rebuild or a refresh of a high-mileage engine.

The black nitriding process hardens the surface of the valve, making it more resistant to wear and heat. This is especially important for exhaust valves, which endure higher temperatures than intake valves. The material itself is well-built to withstand the repeated impact of seating against the valve seat. These valves are designed as direct replacements for your stock TB48DE exhaust valves, meaning they should fit right into your existing valve guides and work with your stock or aftermarket valve springs and retainers.

When you're putting an engine back together, using new, well-made valvetrain components like these can make a noticeable difference in performance and longevity. Make sure you have all the necessary seals and hardware before you begin assembly.
