Supertech Nissan SKYLINE RB25 DOHC 24V (w/Solid Lifters) Dual Valve Spring Kit

Supertech is well-known for making a wide range of performance engine components, and this dual valve spring kit for the Nissan RB25 DOHC 24V engine with solid lifters is a prime example of their focus on the performance aftermarket. If you're building a high-revving RB25, you know how critical it is to have valve springs that can keep up with aggressive camshafts and higher RPMs. This kit is designed to handle those demands, ensuring your valvetrain stays stable when you push the engine hard.

This kit includes dual springs, meaning you get an inner and outer spring for each valve. This setup offers increased stability and better control over valve motion, especially at high engine speeds. The springs are made from strong, high-tensile wire, which is crucial for maintaining consistent pressure and preventing valve float. They are designed to work with solid lifters, which are common in performance builds where precise valve control is paramount. You'll want to make sure you have the correct camshafts and retainers that are compatible with this type of dual spring setup to get the most out of it.

When installing this kit, it's important to follow the manufacturer's specifications for spring height and seat pressure. Proper installation is key to achieving the performance and reliability you're looking for from your RB25 build. This kit is a solid option for anyone serious about getting the most out of their Nissan Skyline's engine.
