Product Details

The COMP Cams 749-1 is a precision-engineered steel valve spring retainer designed for high-performance engine applications. This Superlock-style retainer features a 10-degree angle specifically designed to work with valve springs having an outside diameter (OD) ranging from 1.500" to 1.550".

Key Features:

  • 10-degree Superlock design for secure valve spring retention
  • Manufactured from high-strength steel for durability and reliability
  • Compatible with valve springs measuring 1.500" to 1.550" outside diameter
  • Precision-machined for consistent performance and proper valve train geometry
  • Ideal for performance and racing engine builds

COMP Cams valve spring retainers are essential components in the valve train assembly, working in conjunction with valve locks (keepers) to secure the valve spring to the valve stem. The 10-degree angle provides optimal clamping force while reducing stress on the valve locks, making this retainer an excellent choice for high-RPM applications where valve train stability is critical.

They had the lowest price and great communication. Will order from them again thanks

I looked around for the best peice for a set of Sparco seats. I found them on autoplicity much cheaper then anywhere else. I figured it would take a few days to ship, but by the time i decided to call for a tracking #, I got an email with tracking # and that my seat was all ready to be delivered the next day. They didnt ship together because they were out of stock for a day or 2. I called about my other seat a few days later and it was already delivered at my door. Any future purchases will be checked with autoplicity 1st.

Best price I could find. Good communication with shipping notification received when item shipped.

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.
