Description

50 States Emissions Legal (E.O. D-701-38) The OEM Duramax cast-aluminum cylinder heads fall short over time - the different heat expansion rates between cast-iron engine block and cast-aluminum cylinder head cause head gasket scrubbing and eventually blown head gaskets. The aluminum cylinder heads are also prone to warping, melting, and/or cracking in high-performance applications where excessive heat is introduced.

PPE's new LB7 Cast Iron Cylinder Head is the ultimate upgrade to your Duramax engine and eliminates any head gasket or cracking concerns. Cast from high-quality alloyed gray iron, the PPE Cylinder Head offers elevated fatigue strength, and heat and creep resistance, which prolongs the cylinder head's lifespan significantly.

PPE Cylinder Heads also share the same heat expansion rate as the stock cast-iron cylinder block no more blown head gaskets. PPE LB7 Cylinder Heads also feature cast-in fuel injector cups and solve the OEM injector cup leaking issue.

Each head comes complete with upgraded valve train components. All valves are made of superior materials and fully nitridated. The tapered valve springs' higher spring rate and lighter retainers/locators enable faster response during higher RPMs and eliminate valve float. Powder metal valve seats provide superior wear and heat resistance. The denser and stiffer material properties from the cast-iron construction also significantly reduce engine clatter.

Whether you have a damaged aluminum cylinder head or a desire for better reliability and longevity on your Duramax engine, the PPE Cast Iron Cylinder Head is undoubtedly the best choice.

Cute and well made, fun toy for dogs of all sizes.
Color: Frog (Green)
My small dogs luv this toy, especially the handle part for playing tug of war. My peekapoo is only 14 lbs. but he loves to get a grip on the handle with his mouth and tug really hard which also stretches the body and makes the crunchy noises! My chihuahua loves it too and she tries to grab the eyes with her mouth. It is a very well made toy with a squeaker and light stuffing in the head which makes me feel good about letting them play with it. It is strong and very cute and I think they will have it for a long time.

Octopus dog toy
My dogs love this toy! They love to play tug of war with it, using the rope legs. The legs will pull out if they are strong dogs! But if the dogs are having fun with it, it isn't a problem. One of my dogs has shredded some of the legs and put a hole in yhe body, but she is a strong chewer. There is a squeaker in the octopus body. They enjoy the toy, so I would recommend it.

Decent toy! Dog ripped off legs after a couple days.
As the title says the toy was pretty durable and it’s made of a good rubber which makes it durable. My dog is a medium sized pomsky and she had a hard time gripping the shell part. I stuffed the middle part with treats which by the way DO NOT do that. My dog got really frustrated bc the treats weren’t coming out and idk what happened bc she ended up gagging and coughing. No throw up tho so good enough for me. While my review seems pretty daunting it’s really not a bad toy if you make sure to keep an eye on the rope appendages.

New pup loves it
Our pup is a chewer but she doesn’t like normally toys or bones unless someone else is also playing with them with her. I searched for interactive toys and loved the little turtle so I decided to try it for her! We both work from home and play with her 80% of the day but that other 20% she needed a toy! My pup LOVES this toy (also loves the box that came with it haha). She plays with it by herself for a super long time and it keeps her entertained. She loves chewing it and also loves trying to get the treats. If you have a dog that’s picky about toys, this is a good one!
