This Mace Torque Lock limited slip differential (LSD) uses a sophisticated design to provide a quiet, automatic splitting of torque. It performs like an open differential under normal driving conditions, automatically transferring torque to the wheel with better traction when ground conditions warrant.

The advantage of the limited-slip differential design is apparent when comparing it to the standard or "open" diff. In vehicles with this older style of diff when one wheel began to slip or lose contact with the ground the slipping or non-contacting wheel would still receive the majority of the power whilst the contacting wheel remains stationary with the ground.

This issue is completely resolved with the Torque Lock LSD. Harnessing a similar configuration to the Harrop and Eaton Truetracs, the automatic torque biasing design makes it the perfect limited slip differential upgrade for any enthusiast that will be using their vehicle for either straight-line drag, circuit, off-road or tough street work.

The proven helical gear technology found in the Torque Lock LSD eliminates the need for wearable parts, resulting in maintenance free traction recognized not only for its durability, but its smooth and quiet operation as well. The low cost and effective operation all make the Mace limited slip differential the ideal choice for performance vehicles.

Dog's BFF
Color: Burger Shape Assorted Color, Size: Small
My 10lb pup LOVES these toys. This is the second set I've bought. First set lasted 5 years. The squeaker can be a little irritating after awhile. But that's what he loves. Great toy for my little guy!

Best Balls Ever!!!
Size: Medium
These are the best balls ever! We have 2 very active ball loving dogs and these bounce very well and they actually hold up with active play and chewing. They still look brand new after daily use for months!

Finally a ball my power chewers cannot destroy
Size: Medium
I have two dogs, an American Bully and an American Pit Bull Terrier, and both of them love to chew. Most balls last a very short time around here before they are shredded or missing big chunks. This one has actually held up. They chase it, tug on it and sit and chew on it, and it is still in one piece with no pieces breaking off. One of my favorite things is being able to put food inside. I add some kibble or small snacks, and they will happily sit and work on it for a long time. It keeps them busy, gives them something safe to chew, and they get a little reward while they play. When they are done, I just rinse it out and it is ready to go again. If you have strong jawed dogs that usually destroy toys, this ball is worth trying. Mine really enjoy it and I feel better knowing they finally have a ball that can keep up with them.

My dog LOVES this ball
Size: Medium, Size: Medium
Does your dog destroy tennis balls in seconds? Yes? Then your dog NEEDS this ball! It's squishy like a tennis ball, fits in ball launchers (even the cheap ones) and bounces when it hits the ground. My dog has been literally playing with this ball all day and not a single mark on it! The only bad thing is that it does not float. Definitely worth the money! Put it in your cart!

Perfect for ball demolishers
Size: Medium
The dogs love the chuck it brand. I don’t know what it’s made of but they go crazy over them. Will not play with another ball. Wonder if it’s “laced” with an addictive scent. Have pits. Very durable. Not able to chew to pieces. Last for about 6 months before there is a small break. I keep a back up because when the ball goes missing the house is in chaos. 😆 🤪
