Ferrea 1.650in to 1.600in .885/1.20/1.65 OD .645/.885/1.20 ID Triple Spring Valve Spring - Set of 16

These Ferrea S10001 valve springs are built with a unique triple spring design, featuring an outer diameter that steps down from 1.650 inches to 1.600 inches, and inner diameters ranging from .645 to 1.20 inches. This specific construction is key to managing the high-RPM demands and valve control needed in performance engine builds. Ferrea uses high-grade spring wire, heat-treated and stress-relieved to ensure consistent performance and durability under extreme conditions. Each spring is meticulously manufactured to precise tolerances, which is critical for maintaining proper valve seating and preventing valve float at higher engine speeds.

The triple spring configuration offers increased spring pressure and better dampening characteristics compared to single or dual spring setups. This helps to ensure that the valves close reliably and quickly, even when the engine is pushed hard. This set includes 16 springs, enough for a complete V8 engine. Ferrea is known for producing well-built engine components, and these valve springs are a testament to their commitment to performance and reliability for serious engine work. They are designed to handle the stresses of aggressive camshaft profiles and higher boost pressures, making them a solid choice for engine rebuilds or performance upgrades where valve control is paramount.

When installing these springs, it's important to follow the manufacturer's recommended spring pressures and installation heights to achieve optimal performance and longevity. Proper setup is crucial for these high-performance components. Ensure you have the correct tools for valve spring installation, as this can be a moderately challenging job requiring specific tools to compress the springs safely and accurately.
