Supertech Toyota Supra (A90)/BMW B58B Conical Spring Kit

Supertech is known for making well-built valvetrain components, and this conical spring kit for the Toyota Supra (A90) and BMW B58B engine is no exception. If you're looking to upgrade your engine's valvetrain for improved performance or to handle more aggressive camshaft profiles, this kit is designed to meet those needs. Conical springs offer a unique advantage by reducing mass in the valvetrain, which can help prevent valve float at higher RPMs and allow for more precise valve control.

This kit includes the conical valve springs themselves, engineered to provide consistent pressure across their operational range. The conical design means the spring gets progressively stiffer as it compresses, which is a more advanced way to manage valvetrain dynamics compared to traditional cylindrical springs. This can lead to a more stable valvetrain, especially when you're pushing the engine hard. The material used is high-tensile spring steel, chosen for its durability and ability to withstand the intense pressures and temperatures found within an engine's cylinder head. This means you can rely on these springs to perform consistently, even under demanding conditions.

When installing this kit, it's important to ensure you have the correct tools and follow the manufacturer's recommended procedures for valvetrain assembly. Proper installation is key to realizing the full benefits of these advanced springs and ensuring the longevity of your engine. This kit is a solid option for anyone serious about optimizing their Supra or B58B engine's performance and reliability.
