Add More Durability to your 6.6L Duramax Build

If you're looking to clean up the clutter under the hood of your L5P Duramax, the Wehrli Upper Coolant Pipe Kit is a simple upgrade that makes a big visual and functional impact. Designed specifically for 2020–2025 Silverado and Sierra HD trucks, this kit replaces the factory rubber upper radiator hose with a precision-fabricated aluminum hard pipe that not only looks great but lasts longer. Each pipe is powder coated in your choice of color, so it blends in or stands out—depending on how you want your engine bay to look. Unlike the stock rubber hose that can sag or deteriorate over time, this hard pipe gives your cooling system a clean, high-end appearance while maintaining a strong, leak-free connection. The kit includes high-quality silicone boots and stainless steel T-bolt clamps for a secure, durable fit.

Fits: 2020, 2021, 2022, 2023, 2024, 2025 GM 6.6L Duramax
