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.

Great Value for a ball my dog loves!
Color: S6-muti-color
I wish these ball were in the subscription program! My dog gets sooo excited by the new ball, but her interest in things lasts for a few days. She kills the squeak within 11minutes, but the squeaker stays in place rather than becoming a chocking or swallow hazard, and she still loves to chew it. Next, we must throw the ball approximately 723 times the first day, possibly 496 times on day 2, and just 3- 4 on day 3, at which point she will chase the ball before hollering "it's over here if you need it," while she checks on the chipmunk den. We currently have 17 of these balls in our yard (because we have given several leftovers to a less discriminating doodle next door). These balls hold up really well, get her extremely active for the first couple of days, and are a much cheaper than doggie daycare (after an active morning with a new ball, she is happy to chew on it and sleep much of the day). I always have these on hand!

Pieces chewed off
Color: white & green
My Aussiedoodle loves it. I throw it down the hallway, it bounces crazy, and he chases it. The only complaint is that he can't chew much of the ball part. So now I have to have it put away and brought out for special playtime.

Lightweight Balls
Color: A.Orange+Blue+Green
lightweight but solid. Unfortunately, I can't bring to dog park for my dog to play with as the larger dogs will destroy them. Not for dogs that chew through everything.
