Product Details

The COMP Cams 947-1 Race Extreme triple valve spring is engineered for high-performance racing engines that demand maximum valve control at extreme RPM levels. This professional-grade spring features a 1.660-inch outer diameter and is designed for a 2.050-inch installed height, making it ideal for aggressive camshaft profiles with high lift and duration.

Key Specifications:

  • Triple spring design for superior valve control and resistance to valve float
  • Outer diameter: 1.660 inches
  • Installed height: 2.050 inches
  • Race Extreme series construction for maximum durability
  • Precision wound from high-quality spring steel
  • Designed for high-RPM racing applications

The triple spring configuration provides increased spring pressure and improved harmonics control compared to single or dual spring setups. This design minimizes coil bind while maintaining consistent valve timing at elevated engine speeds. Each spring is manufactured to strict tolerances to ensure reliable performance in demanding racing conditions. Sold individually to allow for exact quantity ordering based on your engine build requirements.

They were Very quick and i was very happy with the service i got!! 9-10*

Best price I could find on the web even after paying for shipping! Shipped in a couple of days and great service!

The ordering process was very simple and the prices could not be beat. The processing time to ship the order was a little longer than usual, but for the price savings, it was well worth it!

Great site. Provided needed technical specs. Shipped promptly. Although I had to ask for the tacking number, it was not emailed, one was provided promptly upon request.

Very good company! Shipped out product very fast!!! I can say i will use them again

This is the easiest purchase I ever made. The visor is great and installation was a breeze. The service by Autoplicity was A-1. Shipping was better than standard. Will buy from them again.
