Supertech Nissan Patrol TB48 Dual Valve Spring Kit

If you're rebuilding the top end of your Nissan Patrol's TB48 engine, especially if you're planning on more aggressive camshafts or higher RPMs, a strong dual valve spring kit is essential. This Supertech kit is designed to handle the increased demands placed on the valve train under these conditions, ensuring reliable operation and preventing valve float. It's a critical component for anyone pushing the limits of their TB48 engine.

This kit features dual springs, meaning there are two springs working together for each valve. This setup offers superior control over valve motion compared to single springs, especially at higher engine speeds. The springs are made from high-strength materials, chosen for their durability and ability to maintain consistent tension over time and under extreme heat. This well-built construction is key to preventing valve float, which can lead to serious engine damage if the valves don't close properly. The kit includes the necessary springs and often retainers, though it's always good to double-check the exact contents to ensure you have everything for your rebuild.

When installing these, pay close attention to the manufacturer's specifications for seat pressure and installed height. Correct installation is crucial for achieving the intended performance and longevity. This Supertech kit is a popular choice for tuners and builders looking to get the most out of their TB48 engine, providing the robust valve control needed for modified setups.
