Product Details

The COMP Cams 740-1 is a precision-engineered steel valve spring retainer designed for high-performance engine builds. This retainer features a 10-degree Superlock design that provides superior valve spring retention and stability at high RPM.

Key Features:

  • 10-degree Superlock design for secure valve keeper engagement
  • Machined from high-quality steel for durability and heat resistance
  • Compatible with valve springs having 1.437" to 1.500" outside diameter
  • Precision-manufactured to tight tolerances for consistent valve train geometry
  • Ideal for racing and performance applications requiring reliable valve train components

This retainer is an essential component in any valve train assembly, working with valve keepers to secure the valve spring to the valve stem. The 10-degree angle design allows for a lower installed height while maintaining proper keeper contact area, making it suitable for high-lift camshaft applications where valve spring clearance is critical.

Quick Service and great pricing!

Fast shipping and the lowest price. Very impressed.

Great prices, have bought from before and will buy from again.

Bought some wire looms for my Chevy from them. Great price, service, and shipping speed!

We looked a lot of places online for the steering stabilizer for our vehicle. We priced and looked to find out who had the best product and fastest shipping. We were so glad that Autoplicity was able to have just what we needed. We highly recommend that you visit autopicity.com for all you vehicle needs and we thank Autoplicity for their expediency in getting us our stabilizer.

Good prices, fast shipping, A+

After checking amazon, ebay, various other general and specialty online parts suppliers and local brick and mortar supply houses, Autoplicity's was hands down the best overall (price + shipping) price for the product.

Best price I could find on the web and great easy to use website. Fast shipping, I am overall very satisfied thanks Autoplocity!
