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.

Cute but slim fit not wide foot friendly
Size: 8.5, Color: Black
Bought these and they were so cute! The only thing was they were wide enough and I don’t typically have a wide foot. I would maybe size up or look for a wider fitting shoe if you have a wide foot. But the style and heel height were perfect not to high! I ended up returning because of the slim fit.

Love these
Size: 8.5, Color: Coffee
So comfortable, stylish, and easy to wear. This can be used with any outfit, whether it’s casual or something more dressy like for work. They are comfortable and easy to wear for eight hours at a time. Heel is nice and thick and very stable, which makes for walking in a heel very comfortable. The color is a beautiful nude, which does not look too chalky or too brown. This is a stable in my
