Product Details

COMP Cams 600-1 hardened steel valve locks are precision-engineered components designed to secure valve spring retainers to valve stems in high-performance and street applications. These locks feature a 7-degree taper angle and are manufactured from hardened steel for exceptional strength and durability under demanding engine conditions.

Key Features:

  • Hardened steel construction for maximum strength and wear resistance
  • 7-degree taper angle for secure retainer engagement
  • 5/16" valve stem diameter compatibility
  • Single groove design for standard retainer applications
  • Precision-machined to tight tolerances for reliable fitment
  • Suitable for street performance and mild racing applications

These valve locks (also known as valve keepers or collets) are essential valvetrain components that prevent the retainer from sliding off the valve stem during engine operation. The 7-degree taper provides a reliable mechanical lock when properly installed with compatible retainers. COMP Cams valve locks are designed to meet OEM specifications while providing the quality and consistency required for performance engine builds.

ordered 4 cans to prime/paint/clear coat some rims. paint came in 2-3 days (incredibly fast). They forgot a can, i emailed and got a reply within 20 minutes, and the can was on my doorstep the next day. im very impressed

No problems so far

I would def order again from them great price and fast shipping.

Wow the quick service and low prices at autoplicity helped me and made it easy to find which car parts retailer is the best!

Good selection, lowest price. Fast shipping. Thanks again!!!

Great price, fast shipping, excellent customer service. I will definitely do business with them in the future.

No problems ordering a leak down tester from Autoplicity which had the lowest price and reasonable shipping charges. The item was well packaged and I would buy from them again.

Autoplicity had the best price on the Wiseco pistons I needed anywhere. Took a little longer to arrive than I expected but apparently that was due to the pistons being shipped directly from the factory. Otherwise a very good experience overall.
