COMP Cams Valve Lock 3/8in Single Groovelock angle and 3 8" valve stem size is a perfect replacement lock for stock engine rebuilds. It is recommended only for street Applications with lighter valve spring loads. It is critically important to make sure valve locks match the valve size. There should always be a small gap between the two halves of the lock when they are properly positioned on the valve stem. If the two halves fit together without a gap, they are too large.

Durable, but not impenetrable! My 68lb Lab got this in the mail today and happily chewed on it for around an hour non-stop. She is a strong and determined chewer, but not a super chewer. She destroys "moderate" rubber chew toys in a flash, but doesn't like hard nylon chews, so finding a rubber chew that can withstand her dilligent gnawing and suit her preferences is a rarity. This one absolutely is a win! The material is most similar to nylabone's Rhino rubber (compared to the Crazy Ball), and with time and continued chomps it will sustain damage, but for my dog (strong, not super chewer) it takes a lot of time to wear out and the early breaks are tiny like specks of sand. It's a safe choice for my dog, and she loves the texture of this toy!

The One

It’s actually indestructible 🤘🏻🫡 My dog has destroyed every “aggressive chewer” dog toy on this website. Finally found one that is true to its name. Will be ordering many more.

Watch your aggressive chewer

My pit bull chewed up one of these in short order. Probably OK for normal dogs but not aggressive chewers. UPDATE: He swallowed a piece and had to have surgery for obstruction…
