Manley Small Block Chevy LS Series .700in Lift Single NexTek High Perf Valve Springs

Manley Performance is well-known for making strong internal engine components, and these NexTek single valve springs are a great example of that. If you're building a high-performance Small Block Chevy LS engine and need to handle .700 inch of valve lift, these springs are designed to do just that. They are built to keep your valvetrain stable at higher RPMs, which is crucial for making power and ensuring reliability when you're pushing the engine hard.

These springs use Manley's NexTek technology, which is an updated design aimed at improving performance and durability. They are a single spring design, meaning they are simpler and lighter than some dual or triple spring setups, which can be beneficial for certain builds. The material and construction are focused on providing consistent pressure and resisting fatigue, even under the demanding conditions of a performance engine. This attention to detail in their manufacturing means you can expect them to perform reliably.

When installing these, remember they are part of the valvetrain, so proper setup and matching with your camshaft and retainers are important for optimal performance. Ensure you consult the manufacturer's installation instructions for the best results.
