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.

Great Knee Support
Color: Blue
The 1-inch thickness provides exceptional support and cushioning, making it ideal for a variety of exercises beyond just yoga. The high-density foam used in this mat is a game-changer. It not only cushions my joints but also retains its shape remarkably well. The carrying strap is a convenient addition, allowing for easy transport wherever I go. Plus, the mat is easy to clean, which is a huge plus after sweaty workout sessions. While the extra thickness might not suit everyone's preferences, especially if you prefer a thinner mat for certain poses, I find it perfect for my needs. It strikes an excellent balance between comfort and stability, providing the right amount of cushioning without compromising stability during balancing poses. Overall, the BalanceFrom All Purpose Yoga Mat will become an indispensable part of my fitness routine. Its durability, support, and easy maintenance make it a top choice for anyone seeking a reliable exercise mat for various workouts.

Perfect For My Routine
Color: Black
I am retired military, so exercise has always been a part of my daily routine. Since the pandemic I have had to adjust, which is hard because the gym has the equipment I have become accustomed to. I didn’t realize how different it was working out there as when I started to work out at home on my hard wood floors (no carpet anywhere). I thought it would be easy but the military exercise mat is entirely too thin and was making my tailbone hurt tremendously, so I had to give up my sit-ups and some other ab exercises. This kind of threw a wrench into my routine and I could start feeling my motivation go away. I decided to take a look on Amazon for a thicker mat. I should have done this long ago because I found this one I’m writing about. It’s the shape of any typical exercise Matt except it’s 1” thick. It appears to be made of a type of foam (not bothering to look at the description right now). When I pulled it out I thought I was going to sink in making sit-ups even harder but it’s firm but not hard. I like it better than what is at the gym. Durability will be hard to determine until I’ve had it a while but I’m definitely excited to start back up on my exercises. I recommend this mat if you have hard wood floors, bad back, bad knees, etc. I thought I read some negative reviews about mats this thick because of yoga and balance but I beg to differ. If balancing is part of your exercise routine, then a mat which makes balance harder is exactly what you want. Exercise is supposed to be challenging and you need to work harder to see a difference. If that isn’t your goal or if balance is a medical issue, this may not be the right mat for you. Something you may not think about is I have chronic foot pain and this mat makes it less painful for me to stand or jump. For me, this mat is perfect.
