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.

Quiet, Powerful, and Reliable — The Best Grinder Set We’ve Owned
Material Type: Updated-Stainless Steel
After going through several cheaper grinder sets that never held a charge, struggled to grind properly, and eventually broke, I decided to invest in a higher-quality set. This one seemed to check all the boxes — sleek design, convenient charging stand, and an overall premium look — so we decided to give it a try. From the moment we charged them up, filled them with our favorite salt and pepper, and started using them, the difference was night and day. The grind adjustment is impressively versatile, ranging from coarse to very fine, and it’s much easier to adjust than on our old grinders. The charging base uses a USB-C connection, which is a big plus — it works with the same chargers we use for our phones. Aside from the initial charge, we’ve only had to recharge them once in more than six weeks of regular use. The grind quality is excellent, the operation is smooth and quiet, and they don’t sound like they’re straining like our previous sets did. If you’ve been disappointed by cheap electric grinders in the past, do yourself a favor and upgrade to this set. It looks great, performs flawlessly, and is absolutely worth the investment.

Very nice grinders!
Material Type: Updated-Stainless Steel
Really nice grinders. I love all of the options for the size of the grind you need, very easy to adjust. They look really nice in the kitchen and Mach my other stainless steel items so that’s a big plus. They hold a lot of salt and pepper as well. The batteries last a nice long time too, and they don’t take long to charge. Functions just as they should, press the button and you’re off to flavor town, very easy to use. Not too heavy, but still feels solid in the hand. The light while you are grinding is nice and bright so I can accurately see how much spice I’m adding to my meals. I love ‘em!

Good quality
Material Type: Updated-Stainless Steel, Material Type: Updated-Stainless Steel
Love this set! The design is very sleek and modern, and the stainless steel looks great on the counter. The charging base is compact, so the grinders stay together and always ready to use. Both the salt and pepper grinders work smoothly and give an even grind with just one button, which is super convenient while cooking. The clear window lets you see how much is left inside, so you know exactly when to refill. Overall, this rechargeable Zadelar set is stylish, easy to use, and a really nice upgrade for everyday cooking and serving at the table.

Easy use, easy grasp salt and pepper grinders
Material Type: Updated-Stainless Steel
Wish I got these earlier as well! Easy to use, easy to fill, easy to charge. Seems quite durable and quality is high, not cheap or pkasticky. Easy to grab unit and press button to dispense. The battery charge life seems long lasting esp since we use these every day for meals. Highly recommend!
