Upgrading to higher pressure rated valve springs is crucial for anyone enhancing the performance and reliability of Cummins engines. These engines often operate under conditions of increased boost pressure and higher RPMs, necessitating stronger valve springs to maintain precise valve control. By installing heavier valve springs, you can effectively mitigate the risks of valve float, a phenomenon where the valves fail to properly close due to inadequate spring tension, potentially leading to engine damage. Thanks to Smeding Diesel's Heavy Duty 24V 104# springs, you can eliminate that possible issue.
Performance-enhanced engines, particularly those running at boost pressures of 50 PSI or greater, demand the resilience and durability offered by heavier valve springs. These upgraded springs provide the necessary tension to keep the valves closed under extreme conditions. Additionally, these valve springs contribute to the longevity of the engines valvetrain components, withstanding the increased stresses and temperatures associated with high-performance applications.
In essence, the installation of heavier duty valve springs is a crucial step for any enthusiast seeking maximum output for their Cummins-powered vehicle.

Very easy to put up and assemble!
Size: 48 inch 3 Tier, Size: 48 inch 3 Tier
We were looking for a nice shelf over our coffee bar, and this industrial pipe shelf was perfect! This was very easy to assemble! Simply put in your anchors and screw in the bases! We ordered the three tier shelf but only needed two, and it was very easy to make that adjustment! I loved that this was solid wood shelving rather than particle board.

beautiful and sturdy
Size: 48 inch 2 Tier
The shelf is beautiful and sturdy. The only small complaint are the instructions to put it together are deceiving because pieces were put together for shipping purposes (we assume) but didn't actually go together which took us a few times to figure out. I recommend putting it together off the wall before trying it on the wall so you know what pieces go where.

Cheaply made
Size: 48 inch 2 Tier
I would not recommend this shelf. There are no instructions included - just a simple drawing of putting it together but nowhere says what drill bit size to use for the plastic anchors which are square on the end and not round. In addition, you cannot fully tighten the iron brackets or they won’t alight on the wall to hang the shelf. Each piece of metal piping has part of the black coating stripped off as well. And on top of that, the bottom of each shelf is unfinished and looks as though they used a filler to hide holes in the shelf. Not worth the money or the hassle.
