SuperPro's rear differential center support bushing drastically reduces the deflection of the OEM rubber differential mount under changing loads - especially rolling on and off the throttle. This offers benefits in throttle response and in manipulating the cars cornering attitude with the throttle as the car will react more quickly and directly to changes in throttle input. In addition the SPF3404-80K offers a vastly extended service life over the soft rubber OEM piece backed by a lifetime warranty. As the higher durometer version of this kit the SPF3404-80K sharpens responses over the standard version but will come with a small increase in NVH due to the higher durometer material Looking for a more daily driver or street car-friendly version? See our SPF3404-70K; the lower durometer version of the rear center differential mount.Shipping Notes

Favorite toy so far!
Color: Purple, Size: Medium (Pack of 1)
I got the medium for my approx 25 lbs border collie mix 4.5 month old puppy. He is in love! He still has his razor baby teeth and didn't do any damage to it the first two uses. A great *quiet* toy to keep him busy. I am putting the replacement rings on autoship now!

1st out of 9 purchases to be broken in a few hours
Color: Purple, Size: Medium (Pack of 1), Color: Purple, Size: Medium (Pack of 1)
I have bought 9 of the PetSafe ring toys. 5 for my pup and 4 as gifts. I have all of the toys (chicken, steak, jack, corn, ball, bone, nobbly). Never have I ever experienced any of them being broken in 1 afternoon. I will be asking for a replacement. But on the positive note, he was exhausted after finally getting the rings off. He has never broken any of the previous toys.

Best toy I've found in a long time!
Color: Purple, Size: Medium (Pack of 1)
I got the small Nobbly for my 3lb puppy, but it's too big for her (she loves the xs bouncy ball one anyway). So my 15yo standard poodle adopted it and loves it. It's really too small for him so I watch him and don't leave him unattended. He is so old with bad teeth, and the softness of the center is great for him. It is totally cleaning his teeth, I see white where I haven't for years. But ZERO bleeding which is awesome. It's easy for him to hold and difficult for him to get to the rings, they last plenty long. I will order this one for him in a larger size, probably the medium. 100% satisfied with these toys! Ps I also have a hard chewing 12yo aussie that breaks teeth on anything like a bone. He gets thru the rings in minutes with the bouncy ball and nobbly, but takes way longer with the jack shaped one. He also likes to chew the purple ends of the jack, not just the rings. But I don't think they're hard enough to break his teeth. All of my dogs are different style chewers, but there is a good variety of designs so you can find the perfect one for your canine friend!

Dog-approved toy!
This dog toy was initially confusing because the instructions did not say or show where to find the power button and charging port. They were nowhere to be found until I realized I could unscrew the bottom part of the ball from the top (see picture). That revealed the button and port -- problem solved. Then on to the dog test. Our dog was initially confused by and ultimately fascinated with the ball as seen in the video. There are several operating modes depending on how active your dog is/wants to be. The toy seems quite rugged, so immune to rough dogplay, at least from a golden retriever. Our dog considers this a hit!
