One of the most overlooked performance parts in most 24V Cummins performance builds is the valve-springs. They may not be something you can see, but we can assure you, they are essential in ensuring your engine is operating properly with all your other performance parts. The factory springs are not designed to handle the elevated boost levels that are typical in modified applications causing valve float. This will drastically hurt your engine performance. This kit is a must have for your performance build.

This kit features improved valve control with increased spring pressure to minimize valve float over a standard spring. Unlike other valve springs on the market, this kit can be used on a wide range of trucks, from stock to performance builds. This is a perfect one-and-done upgrade that lets you modify your engine for more power down the road. Each spring is computer load mapped and then matched within 1 lb of seat pressure followed by a stress relief process to ensure quality and long term reliability. This set re-uses your locks and retainers, and is backed by a 1 year manufactures unlimited mileage warranty.

This valve spring set is ideal for the enthusiast that is running an aftermarket cam, upgraded or compound turbo kits, and fueling upgrades. These springs are ready to install using your factory retainers and locks. These springs have a reduced OD and will fit all 1998.5-2002 cylinder heads regardless of casting inconsistencies.

Good looking shelves and easy install - skip the included drywall anchors
Color: Black, Number Of Shelves: 2, Size: 22in
I installed these shelves in a bedroom to get things off my dresser and some decor. Once mounted they look really nice. The black finish looks clean and modern and they blend in well with the room. Installation was pretty straightforward. The metal bracket mounts to the wall first and then the shelf slides over the bracket. As long as you take your time lining things up it’s a simple project. One thing I strongly recommend is not using the white plastic self-drilling drywall anchors that come with the kit. I’ve used that style before on other projects and they tend to strip out easily and leave larger holes in drywall. I used better anchors instead and the shelves mounted much more securely. The rest of the hardware worked fine and once installed the shelves feel solid and hold items well. Pros - Clean modern look - Easy installation - Feels solid once mounted - Good size for books or decor Cons - The small level included isn’t very accurate — use your own level - One of the metal brackets was slightly bent out of the box but straightened out easily Helpful tip: Use your own level and better drywall anchors if you have them. It makes installation easier and the shelves will mount much more securely. Final thoughts: For the price these are nice looking floating shelves that install easily and work well for light storage and decor.

The shelves sag away from the wall overtime
Color: White, Number Of Shelves: 2, Size: 15.7in, Color: White, Number Of Shelves: 2, Size: 15.7in
Although the wood quality and finish of the shelf are clean and well-made, the main issue is that the shelves begin to sag over time while holding around 10 pounds, even though the product listing claims they can support up to 20 pounds. They may perform better on a brick wall, but on drywall you should be cautious. To fix the problem, I had to purchase floating shelf brackets for support, which solved the sagging issue. However, this defeats the purpose of the “floating” aesthetic. Since the shelf is in my bedroom, I can overlook it, but I personally wouldn’t install these in a common area if I wanted a clean floating look.
