Product Details

Supertech is known for making well-built engine components, and this dual valve spring kit for Opel Z16/Z18 LER/A18XER 16V engines is no exception. If you're rebuilding the top end of your engine or looking to handle more aggressive camshaft profiles, a strong valve spring setup is crucial. This kit is designed to work with your factory valve seats, simplifying installation and ensuring compatibility with your existing cylinder head components.

This kit includes dual springs, which means you get an inner and outer spring for each valve. This setup offers improved stability at higher RPMs by reducing the chance of valve float, especially when you're pushing the engine harder. The springs are made from high-strength materials, built to withstand the repeated stress of opening and closing valves under demanding conditions. Using the factory seat means you don't need to machine the cylinder head to fit new spring seats, which can save on labor costs and complexity during your build.

When installing this kit, remember that using the factory valve seats is part of the design. This makes it a more straightforward upgrade compared to kits that require specialized seats. Ensure you follow the manufacturer's instructions carefully for proper installation and to achieve the intended performance benefits for your Opel engine.
