S&S Diesel Motorsport, renowned worldwide for its expertise in common-rail diesel injection, has devised a solution to address the persistent issue of CP4.2 high-pressure pump failures afflicting the LML Duramax engine. Their approach tackles the problem preemptively by replacing the problematic CP4.2 with the dependable and proven CP3 high-pressure fuel pump. The CP4 high-pressure pumps have emerged as the Achilles' heel of the LML Duramax engine due to their elevated failure rates, often resulting in the catastrophic failure of the entire, and notably costly, high-pressure system, including injectors, rails, and lines. S&S Diesel Motorsport introduces the industry's CARB-complaint (EO #D-756) 50 State CP3 conversion for the LML. This is a comprehensive solution that provides all the necessary hardware for seamlessly swapping out the troublesome CP4 with the robust CP3, and it requires no alterations to tuning while preserving factory emissions control equipment at an affordable price.Shipping Notes

Loved it!
Color: Black, Size: 15.7"
These floating bathroom shelves are exactly what I was looking for. They’re sturdy, well-made, and look really nice once mounted. Installation was straightforward, and all the necessary hardware was included. The shelves hold a good amount of weight and are perfect for organizing bathroom essentials without taking up floor space. They add a modern, clean look to my bathroom and make it feel more organized. Great quality for the price — I’d definitely recommend these to anyone needing extra storage.

I recently installed these bathroom shelves, and they completely exceeded my expectations. The quality feels solid and durable, and once mounted, they sit perfectly level without any wobble. I love how clean and modern they look — they instantly elevated the whole feel of the bathroom.
The shelving space is surprisingly generous. I’m able to store everything from toiletries to décor pieces without the shelves feeling cluttered or overloaded. The finish also holds up well in humidity, which is a big deal for a bathroom environment.
Installation was straightforward, the hardware included worked perfectly, and the shelves feel like they’re built to last. Overall, these shelves deliver both style and function, and I’m extremely pleased with how they turned out.
Highly recommended if you want a simple upgrade that makes a big impact.
