Review MANLEY Polished Nextek.p. Double Valve Spring Kit Gm Gen fits LT4

The Manley 2635LT4KS Nextek HP Double Valve Spring Kit for GM LT4 engines is a high-performance upgrade designed to enhance the durability and reliability of your engine's valve train. This kit is specifically engineered for use in high-performance and racing applications, where increased valve spring pressure is required to ensure consistent performance under extreme conditions.

Each valve spring in this kit is manufactured using Manley's proprietary Nextek alloy, which provides superior fatigue strength and durability compared to traditional valve spring materials. The double-spring design utilizes a primary and secondary spring to provide a more consistent and stable valve force throughout the RPM range. This results in improved engine response, increased power output, and reduced valve float at high RPM.

The Manley 2635LT4KS Nextek HP Double Valve Spring Kit is designed to fit GM LT4 engines, including those found in the Corvette C7.R and Z06, as well as various aftermarket performance applications. The kit includes eight valve springs (four intake and four exhaust), eight retainers, eight locknuts, and eight spring compressors to make installation as straightforward and hassle-free as possible.

The Manley 2635LT4KS Nextek HP Double Valve Spring Kit is a must-have upgrade for any GM LT4 engine looking to maximize its performance potential. With its unmatched durability, consistency, and stability, this kit is an essential investment for any serious performance enthusiast or racing team.
