1975 SBC 5-13/16 with 3/4" shaft water pumpSmall block Chevy running hot? This is the 5 13 16" hub with the 3 4 shaft used on the 350 5. 7L. It has an increased vane count and a reduced casting to impeller vane clearance. It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids. FlowKooler introduced the first hi flow pumps and continues to improve

Small block Chevy running hot? This is the 5-13/16" hub with the 3/4 shaft used on the 350/5.7L.  It has an increased vane count and a reduced casting-to-impeller vane clearance.  It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids. 

FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot Ford engine? Because it has been proven time and time again that reducing the cycle time between the heat source and the heat sink creates more opportunities to shed heat and drop engine temperatures.

From 0-3,300 RPM…Nothing Beats a FlowKooler!

Obsessed, crappy rope
My pitbull mix is obsessed! I was worried he might break it, but he has used it everyday for the past week and we've had no issues. The reason I docked a star is because the rope it comes with lasts minutes. I'm still trying to figure out a good solution of what to tie onto the top. Regardless, he loves it without anything on it, but he chews on the connector piece so I'm worried he will break it if I let him go.

Good For Heavy Chewers So Far
Color: Onyx Black - Most Durable
Solid quality. My Doberman is a power chewer and I am looking for a toy that he can't destroy in 2 seconds. If a ball lasts more than an hour it is a miracle. It has a sturdy design and is more heavy weight than the other "non-destructible" balls he has. He has only had his ball for one day so we will see how long this ball lasts him. It is the size of a tennis ball, firm, little to no bounce, and seems built for heavy chewing.

Great Product, 2 years and running!
Color: Onyx Black - Most Durable
It’s been almost 2 years and my dogs haven’t destroyed them yet. I have a Pitbull and a Pit/Cosro mix. They destroy every toy we’ve given them, except these toys. Great product 100% worth the money

Perfect for HEAVY chewers
Color: Onyx Black - Most Durable
My dog is a heavy chewer. Destroys everything that’s not very hard rubber, hard plastic, or hard material. He LOVES this ball. I think it’s his favorite. Plus, it bounces great so you can play with your dog. Very well constructed- probably indestructible or will at least last a very long time. Easily worth the money.

The only toy my dogs can’t destroy and love
Color: Onyx Black - Most Durable
I am thrilled to have found one toy my dogs don’t destroy immediately. They have torn up Fenrir hammers, the black kongs of all sizes, the monster k9 stick, nylabones, and they don’t like the goughnut at all (it stinks like a bad tire). This is the first one they both love and haven’t been able to destroy immediately. It does allow little tooth marks, but that’s what makes it fun for them. They are very happy playing with it and I’d say this one was worth every dollar. Update Months Later: We’ve gone through 2/3 now. I got two initially, and one has lasted long term. They still haven’t completely destroyed it. They did destroy a second one quickly so I suspect a flaw in it. They sent me a new one and they took a while, but they did destroy the third to the point we had to throw it away. Despite that, one still remains and our dogs still love it. It’s still the best for the money compared to others. We have two Bully XL’s that are each close to 100 pounds.
