South Bend NV4500 1-3/8" Input Shaft Upgrade 94-03 Dodge 5.9L CumminsThe NV4500 transmission has been a strong and reliable manual transmission for years. Used in many applications, replacement parts for these are innumerable. For those that are wanting to increase the strength of their transmissions, a weak point is the factory 1 1 4" input shaft. Because of this, many upgraded clutches for these transmissions require you to upgrade to the later style NV5600 1 3 8" input shaft. To further strengthen these shafts,

Not indestructible, but well worth it
Color: GT-2P, Color: GT-2P
First things first…it’s solid, literally. Very hard and if you have tile or wood floors, it’s ridiculously loins when it hits the floor. With that said, we’ve had our dogs chewing on these for about a month now. All 3 are aggressive chewers. As you can see in my pic, there are signs of chewing on the ends of the bone. I’ve noticed they all seem to gravitate towards them assuming they think they can chew through it. Not the case. The material itself made of is hard but I almost think they enjoy the feeling of the bone against their teeth and gums. I regularly watch our biggest chewer lay on the couch for what seems like hours just biting on it. The bone itself has held up extremely well and haven’t shown any signs of splintering, breaking, or falling apart. This making us feel the bone is safe considering how much they love to chew and how well it’s held up. It looks like a bone. This seems to be a factor in them wanting and/or seeking it out when they want to chew on something. Great to keep close in the living room and gets almost immediate engagement from all of them when I pull it out. Well worth it if you have problem dogs that chew everything and anything. Great as a distraction and from what we’ve seen, great for hours of engagement. Highly recommend for sure.

Excellent toy for aggressive chewer dogs!!!
Color: GT-2P, Color: GT-2P
These treats are super heavy duty! My German shepherd is a good eater. This includes chewing on many things that are not make to be dog toys. I need to keep her occupied and chewing toys that are made specifically for aggressive chewers. She’s quite wily and can usually take apart those supposed aggressive chewers toys very fast. That’s why I love these toys. They actually are for aggressive chewers and keep my best friend busy chewing for days! I love that you can add soft treats or doggy toothpaste to the grooves in these. The raised bumps on the toy are also supposed to help clean teeth. A dog toy that helps with bad breath? I will take two please! Plus, love that these can be cleaned easily, even in the dish washer, and have long lasting bacon scents that my girl loves.
In all seriousness, these are strange looking but very functional chew toys. They do not make a mess (other than my dog drooling all over - haha). You can even add doggy peanut butter! Perfect for big dogs and aggressive chewers. I would caution against using for any elderly dog and or dog that doesn’t have strong teeth.
Good value for the price (a little over $5 each on sale) considering how long these toys last. Also a good gift.

Dog approved!
My dogs love this. This is the 3rd time I have bought them. They are entertained for hours and keeping their teeth strong.
They pay me no attention when they have this toy. 😂
