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.

It’s Okay!
Size: One Size, Color: Soft Mahogany
Everything was just okay about this bag. I expected more of a high quality and gorgeous suede and it really looked like I could have gotten it at target. It did not lay quite right as a crossbody for me so I returned it. The color is very pretty and it is made very well.
