GAP has the Wehrli Custom Fab WCF100199 Duramax Up-Pipe Bolts that will replace the broken bolts on your 2017-2024 GM 6.6L Duramax L5P. The factory 8mm fasteners used on the 2017 and newer 6.6L Duramax engines to connect the up pipes to the exhaust manifolds and turbocharger pedestal are known to fail, even after a few short years. During performance development work on these engines, Wehrli Fab has seen frequent incidences of the stock bolts seizing or breaking in the manifolds and pedestal on brand-new, low-mile trucks in rust-free environments. This bolt kit contains 12 specially selected high-strength ARP fasteners and matched washers with a pack of assembly lube designed as an upgrade to the smaller and failure-prone bolts on your truck. This simple, cost-effective upgrade will give you peace of mind and ease of serviceability for your stock or modified trucks.
Features:
- Black Oxide Coating
- ARP Bolts & Washers
- ARP Fastener Assembly Lubricant

Good but better options out there.
Good ball, but is a cheaper version of the Foamster sold online. The rope is cheap and comes apart, and can be abrasive to a dogs mouth. The Foamster uses a higher quality ball and are more durable and use grippy biothane straps rather than cheap rope. They are also made to order in the USA with lots of fun colors. Worth the extra money if your dog likes these balls.

Fun toy for fetch
Size: Medium, Number of Items: 1
Daisy loves this toy. I found it from her dog trainer, and it makes rewarding her with a quick tug of war and fetch really easy. Also it’s shockingly durable. It looks like foam, but she has not destroyed this one.

One Tough Ball!
Color: Blue
Our dogs are loving this ball. Our 1 yr old hound is a world-class chewer and he can't make a dent in this ball. The interactive buzzing and bouncing keeps them entertained for long durations. It's a mite noisy but the barking from the 1 yr old is much louder, lol. Even turned off, they like playing with it and chewing on it. Based on the tough construction, we think it will last much longer than traditional chew balls.

My puppy’s favorite
Color: Orange
Great quality and built to last. My dog really enjoys playing with it and stays entertained for quite a while. The material is strong yet safe, and the included drawstring bag is a convenient extra for easy storage.
Is colorful and my become my puppy’s favorite.

If you love your dog…don’t buy this.
Color: Orange
We have a nonaggressive English cocker. She opened the ball every time she played with it. And yes, we are closing it as hard as we can. I do not recommend this toy for any dog! This is a dangerous toy for a dog that is not supervised.
