Supertech Toyota Supra 2JZ-GE/2JZ-GTE Conical Single Valve Spring Kit

This kit includes the Supertech conical single valve springs and retainers specifically designed for the Toyota Supra 2JZ-GE and 2JZ-GTE engines. These components are crucial for the proper operation of your engine's valvetrain, especially when you're looking to upgrade your camshafts or increase your engine's redline. The conical shape of these springs offers a unique advantage, allowing for a lighter retainer and a more compact setup compared to traditional dual springs, which can help reduce valve float at higher RPMs.

Supertech is known for producing well-built valvetrain components, and this kit is no exception. The springs are made from high-tensile steel, chosen for its ability to withstand the repetitive stress of opening and closing valves under demanding conditions. The retainers are designed to work seamlessly with the springs, ensuring a secure and stable valvetrain assembly. When installing these, pay close attention to the manufacturer's specifications for seat pressure and open pressure to ensure optimal performance and longevity for your engine. This upgrade is often part of a larger build aimed at extracting more power and reliability from the legendary 2JZ engine.

Upgrading your valve springs is a significant step in building a high-performance engine. It's important to ensure all other valvetrain components are in good condition and compatible with the increased demands. This kit is a solid option for enthusiasts looking to push their 2JZ engine beyond its stock capabilities, providing the necessary support for more aggressive camshaft profiles and higher engine speeds.
