Supertech Nissan SKYLINE RB20 DOHC 24V (w/Hydraulic Lifters) Single Valve Spring Kit

This Supertech single valve spring kit is built with a specific spring rate designed to handle the demands of an RB20 DOHC 24-valve engine equipped with hydraulic lifters. The kit includes everything needed to replace the stock valve springs, ensuring proper valve control under higher RPMs and increased camshaft lift. When you're rebuilding the top end of your RB20, especially if you're upgrading the camshafts, the stock springs might not be able to keep up. This is where a well-built aftermarket spring kit like this one becomes essential for reliable performance.

Supertech uses high-tensile chrome silicon wire for these springs, which is known for its strength and ability to maintain its spring rate over time, even under repeated stress. This material choice helps prevent valve float, a condition where the valve doesn't close properly at high engine speeds, which can lead to serious engine damage. The kit is designed as a direct replacement for the factory springs, making installation more straightforward for a mechanic familiar with engine work. You'll want to ensure you have the proper tools for valve spring compression and removal, as is standard for this type of engine work.

This kit is a solid option for anyone looking to get the most out of their RB20 engine build, whether for street performance or track use. By providing consistent valve control, these springs help maintain engine power delivery throughout the rev range and protect your engine from potential damage caused by valve float. Always refer to the manufacturer's installation instructions for specific details and torque specifications.
