Product Details
If you're working on a Chevy LS, LT1, or LT4 engine and looking to upgrade your valvetrain for higher performance, this Manley valve spring and titanium retainer kit is a solid choice. It's designed to handle the demands of more aggressive camshafts and higher RPMs, giving you the stability and durability needed for racing or serious performance builds. This kit takes the guesswork out of matching components, so you can be confident everything works together seamlessly.
Manley uses a special chrome-silicon alloy for their NexTek? valve springs, which are shot-peened to military specifications. This process greatly improves their resistance to fatigue and ensures they maintain consistent pressure even at extreme engine speeds. The kit also includes titanium retainers, which are CAD-designed to be as light as possible without sacrificing strength, helping to reduce valvetrain mass. You also get CNC-machined I.D. spring locators, heat-treated steel valve locks designed for 8mm valve stems, and Viton? valve stem seals that stand up well to heat and oil.
This is an all-inclusive kit, meaning it comes with everything you need to replace your valve springs, retainers, locks, locators, and seals. The manufacturer notes that the maximum lift figures can vary depending on your specific cylinder head setup and installed height, so it's always a good idea to double-check those measurements during installation. This kit is built for performance and durability, giving you peace of mind when pushing your engine hard.
