Product Details

The COMP Cams 980-12 is a high-performance single outer valve spring designed for use in racing and high-performance engine applications. This valve spring is engineered to provide reliable valve control at elevated RPM ranges while maintaining consistent spring pressure throughout the engine's operating range.

Key Features:

  • Single outer valve spring design for dual spring setups
  • Manufactured from premium chrome silicon steel for maximum durability
  • Precision wound to exact specifications for consistent performance
  • Heat-treated for optimal strength and fatigue resistance
  • Designed to work with COMP Cams camshaft and valvetrain systems

This outer valve spring is ideal for upgrading your engine's valvetrain to handle increased lift and duration from performance camshafts. The 980-12 provides the outer spring component needed for dual spring configurations, which help prevent valve float and maintain positive valve control at high engine speeds. COMP Cams valve springs are engineered to deliver consistent spring pressure across the entire RPM range, ensuring reliable performance in demanding racing and high-performance applications.

fast shipping, lowest prices.

I ordered an Optima battery for my truck after I did a Google search for the battery. Autoplicity was the cheapest on the Web. Even cheaper then eBay. They got me hooked. Thanks Autoplicity

First time using Autoplicity. Found some great pricing on their site. Plan on doing plenty of mods to my new truck and would definetley recommend them and would be using them again very soon.

Best price, reasonable shipping, and they even gave me a discount AFTER I placed the order.
