Review TRW 12 Vs1006 Engine Valve Spring For Chevrolet fits 350 400 1967–1980

The TRW VS1006-12 engine valve spring is a crucial component in the proper functioning of the 1967 to 1980 Chevrolet 350 and 400 engines. This valve spring is specifically designed to provide the necessary force to keep the engine valves closed during the compression and combustion strokes, ensuring efficient and effective engine performance.

The TRW VS1006-12 valve spring is a dual-spring design, meaning it consists of two separate springs working together. The outer spring, also known as the compressor spring, is responsible for compressing the inner or seat spring during the valve closure. The inner spring, in turn, applies the force to keep the valve closed.

This valve spring is made of chrome silicon steel wire, which offers excellent fatigue resistance and durability. The springs' open-ended design allows for easy installation and removal, making it a popular choice among mechanic shops and DIY enthusiasts.

Each spring comes with a factory-installed retainer and lock nut, ensuring a secure fit and proper functioning. The TRW VS1006-12 valve spring is also compatible with various valve sizes and engine configurations within the specified model range.

By choosing the TRW VS1006-12 engine valve spring, you'll be investing in a reliable and efficient solution for your classic Chevrolet 350 or 400 engine. This part is designed to meet or exceed the original equipment specifications and is backed by TRW's reputation for quality and customer satisfaction.
