Additional Info

Why Pacbrake added a bump stop to their bags?

Peace of mind. Customers want a bump stop to prevent bottoming out from loss of air bag pressure, an extremely rare event that could damage the air bags or potentially the frame of the truck. Think of it as an "insurance policy" against bottoming out.

An additional benefit is that you can run these airbags at 0 psi when unloaded for superior ride comfort.

Are bump stops necessary?

No! For those that require max travel in their air bags, to raise and lower their rear end to pickup trailers or boats, or for those that take their trucks off roading, air bags without bump stops are recommended. Consider the HP10120 ALPHA HD air bag.

Very nice, LOUD toy
Style: Crocodile
My parents' dog had the shark version of this toy already, and I looked to see if there were any other versions of the same toy. I found this crocodile. This thing is hysterical when he plays with it. I think each squeaker makes a slightly different sound, so you can hear him switch from 1 part to another. This is not for you if you like quiet. It is very loud but our dog doesn't like toys that don't squeak. The shark has held up for along time, and the crocodile is doing well so far. He's pretty rough on his toys, but he hasn't torn these or broken the squeakers. The fabric is soft, and it's well sewn. There's no stuffing in the body or limbs, so small holes don't really matter. It's big enough for larger dogs (ours is 45lb). The price was very good for a large toy that's high quality.

It's holding up better than I thought it would
Style: Snake
*EDIT* I originally gave this toy a 1 star rating. I changed that to a 4. Even though my dog immediately put holes in it, it's still holding up. She absolutely loves her Snakey, and takes it to bed with her. She hasn't even chewed the eyes off, like she would normally do. There's even still a piece of the tongue left lol! I gave this to my dog tonight. She's already torn a hole in the tail. I just found a hole next to a squeaker, and she's almost chewed the tongue off. This toy is not durable at all. I do not recommend this for any dog that likes to chew.

Not recommended for an aggressive chewer.
Style: Crocodile, Style: Crocodile
24 hrs. after giving this to my Frenchton, all 3 squeakers were out and disabled, one foot remained, head was half way off, back end was chewed away. This alligator is no match for an aggressive chewer.
