Upgrading to larger valve springs is crucial for anyone enhancing the performance and reliability of Cummins engines. These engines often operate under conditions of increased boost pressure, higher RPMs, necessitating stronger valve springs to maintain precise valve control. By installing larger 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 110# 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 larger valve springs. These upgraded springs provide the necessary tension to keep the valves closed under extreme conditions. Additionally, larger 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 larger, heavier duty valve springs is a crucial step for any enthusiast seeking maximum output for their Cummins-powered vehicle.

Nice Fit
Color: Black, White, Light Gray, Size: 3X-Large
I picked this up looking for something simple but clean, and it delivered. The fit is comfortable, the material feels solid, and it looks good without needing much effort. It’s one of those pieces you can throw on and still look put together.

Good value, soft and comfortable
Color: Black, Army Green, Light Gray, Size: 4X-Large, Color: Black, Army Green, Light Gray, Size: 4X-Large
Initial thoughts are very positive with this 3 pack shirt set. The green is similar to an OD military green and the black and gray are standard color shades. Material is soft and sizes are true to size. The mock turtleneck isn’t too tight but may still be a little annoying to some people. I do question the amount of spandex in these shirts. Tag says 5% but these shirts are extremely stretchy and feels like a higher spandex content. It’s also a little tough to figure out which way is the front of the shirt. Visually rhe front does have a lower collar line than the back but would still be nice to have a brand tag printed in the back of the shirt for quicker identification.
Overall for roughly $12 a shirt these are a good choice for everyday wear. I will update rating if these shirts fail to meet expectations after further use.

Just what I wanted.
Color: Black, Navy Blue, Wine Red, Size: 5X-Large
These may have just become my standard shirt to wear. Feels good whether tucked or out. Drapes well and fits well. So far, I can see it adjust to the different undershirt I may wear. Will probably order another set in other colors and a back up set of the basics because they will get worn a lot.
