Fleece Performance 11-14 GM Duramax 2500/3500 Heavy Duty Trans Cooler Lines

Fleece Performance is known for making well-built parts for diesel trucks, and these heavy-duty transmission cooler lines are a prime example. If you're working on a 2011-2014 Chevrolet Silverado 2500 HD or 3500 HD, or its GMC Sierra counterpart, these lines are designed to replace your stock ones and help keep your transmission running cooler.

These lines are built with durable materials to handle the demands of a heavy-duty truck. They are designed to fit right, making the installation process smoother than trying to adapt aftermarket parts that weren't made for your specific application. Better fluid flow means your transmission can dissipate heat more effectively, which is crucial for preventing wear and tear, especially when towing or hauling heavy loads.

This kit is a solid option for anyone looking to ensure their transmission cooling system is in top shape. It's a direct replacement for the factory lines, so you can be confident in the fit and function.
