Product Details

The COMP Cams 604-12 hardened steel valve locks are precision-engineered components designed for Chrysler engines requiring reliable valve train retention. This set includes 12 individual locks, providing enough for a complete 6-cylinder engine or replacement parts for V8 applications.

Key Specifications:

  • 7-degree locking angle for secure valve spring retainer engagement
  • 3/8" stem diameter compatibility
  • 4-groove design for maximum contact area and retention strength
  • Hardened steel construction for wear resistance and durability
  • Street performance application suitable for daily drivers and mild performance builds

These valve locks (also called valve keepers) are critical components that secure the valve spring retainer to the valve stem. The 4-groove design distributes clamping force evenly around the valve stem, while the hardened steel material ensures long-term reliability under the constant cycling of valve operation. The 7-degree taper angle is a common street performance specification that provides excellent retention while allowing for smooth valve train operation.

COMP Cams valve locks are manufactured to tight tolerances to ensure proper fit and reliable performance throughout your engine's service life.

Autoplicity had the lowest price by far and shipping was very fast (ordered Wednesday evening, arrived Saturday morning). I will definitely order from Autoplicity again!

thanks

Very pleasant order over the phone. Gentleman was smart, cheerful and helpful.

efficient.

Autoplicity cares about there customers. I ordered a flash programmer and got to the last page and never got a confirmation of the order. I used the website chat and talked to somebody about it right away. So I ordered again and got a conformation. But both went though. Autoplicity called me next day a.m. to see if I made a mistake. Thanks for letting me know and correcting to one order. Saved me from shipping back a product I dind't need.

Good products with low prices. Easy website and pament options.

Exact product as promised with the best price on the internet. Product shipped fast and had a tracking number to keep me up to date on my order. I would order from again without hesitation and will tell friends.
