COMP Cams Valve Locks Eb Hi Perf For Gm - Set of 100Most people believe that the tang inside a valve lock holds the retainer and valve spring in place while the engine is running, but this isn't the case. The cross section of material in the tang is not strong enough to withstand open spring loads of 1000 lbs. or more. The sole purpose of the tang is to temporarily locate the lock, retainer and spring relative to the valve until the taper of the retainer can nest around the outside surface of the lock.

Most people believe that the tang inside a valve lock holds the retainer and valve spring in place while the engine is running, but this isn't the case. The cross-section of material in the tang is not strong enough to withstand open spring loads of 1000 lbs. or more. The sole purpose of the tang is to temporarily locate the lock, retainer and spring relative to the valve until the taper of the retainer can nest around the outside surface of the lock. This creates a collet effect that binds the two together. The more spring force exerted on the retainer (as the valve opens), the more force applied by the collet effect to keep the retainer and lock in place. With the emergence of valve sizes other than the standard 5/16", 11/32" and 3/8", it is important to make sure the 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. If the locks fit tight to the stem and leave a gap between the middle of the lock and the O.D. of the stem, the locks are too small. Our line of stock replacement 7 valve locks for stock engine rebuilds are recommended only for street applications with lighter valve spring loads and are stamped and hardened for superior wear resistance. Also available are machined 7 locks and titanium Super 7 Locks for some applications. They offer the same valve spring location accuracy as our Super Locks without the need to change to 10 degree retainers.

Works Great! Very bright
My dog and I really love this ball. Bought this so we can play in the field behind our house at night. Tried other balls, like the glowing ones, but they're not bright enough. Other battery powered balls don't stay on long enough and I got tired of looking for them in the dark. This one stays on, depending on the switch setting, either 5 minutes, or indefinitely until it's shut off or until the battery dies. The battery, according to the instructions, should last 10 hours before needing recharging. I've charged it once when it was received, haven't had to re-charge it yet, played with it about 7 nights now 20 min each time and it's still going. Others have said it's not very durable, but I've found it to be durable enough to play catch with our border collie, haven't had any issues. but I don't let him chomp on it all he wants, just throw it and he brings it back. I suppose if your dog is an aggressive chewer and you let him just sit there and go to town on it, it won't last very long, just like any other ball. We use this ball only at night when needed, and use cheaper balls at other times to increase its life span.

THIS IS A MUST-BUY! If you have a dog--you NEED this ball!
Color: Orange
We have two 18-month-old chocolate Labs (brothers—basically twins with paws). The best time to walk them is early morning or just before dark… which is exactly how we managed to lose approximately 9,472 tennis balls in our cornfield. RIP, brave yellow soldiers. So I went searching for a ball that didn’t just glow—I wanted one that full-on lights up like a tiny dog disco. Enter this LED ball. Game. Changer. Our walks are now way more fun. The ball bounces, flashes, and changes colors like it’s auditioning for a rave. People literally slow their cars as they drive past our field just to watch the light show. I’m not saying we’re local celebrities now… but I’m not not saying that either. And here’s the real magic: when the boys get distracted and abandon the ball (because squirrel), it stays lit so I can actually find it. We also bought a ball launcher from Walmart for about $9, and the LED ball fits perfectly—same size as a tennis ball, just 100x cooler. This ball is waterproof and mostly floats, although I haven’t been brave enough to throw it into the pond or river because I’m positive my dogs would treat that as a full-scale navy search mission and never find it again. It’s easy to charge, and even with 2–3 hours of walking daily, I only have to plug it in every few weeks. We’ve had it for months now and it’s still going strong—super durable. We don’t let them chew on it off-walk (because Labs), but during fetch? It’s a champ. Also—small but hilarious detail—when they catch it, their mouths light up. I have accidentally created glow-in-the-dark dogs. I love this ball so much I’m buying a backup because life without it is not an option. Best dog toy EVER. Whoever invented this deserves a medal, a parade, and a lifelong supply of tennis balls they’ll never lose again. 🐾💡

DISAPPOINTED
Color: Blue
only lasted 3 months after about a dozen uses. The LED core fell out and now it's totally useless. Not worth the cost at all. Disappointed because my dogs really loved them.

Dog is obsessed with this.
The spa works as intended it lights up at night, which is super helpful for short winter days and for when the snow starts to pile up, it illuminates the snow pile that dog dropped it in so I can find it. I haven’t actually charged it yet. It came fully charged and has been in use for over a week without needing a recharge. We only use it on outside excursions together. I keep it in my pocket on walks in case he needs something in his mouth or an incentive to run a little off leash. I like that there are two settings to the light which I didn’t notice when I ordered it. One will shut off after five minutes of inactivity to save battery, which is really convenient so I don’t have to keep on screwing it to turn it on and off or there’s a second setting where the light stays on until you manually turn it off. We have it on the battery saving mode and we have never lost it. Overall, a really fun toy that even the neighbors, tiny dog who can barely pick it up and enjoys. It’s not really soft for like chewing, but that also means he’s not going to destroy it. It is a heavy ball to throw, but not too bad. One of my favorite purchases for this puppy.
