Upgrade Your Return Line Before It Lets You Down

If you’ve got a 2013–2024 Ram with a 6.7L Cummins under the hood, you already know that rubber hoses don’t last forever. The factory heater return hose is a common weak link, especially after years of heat, pressure, and daily use. Fleece Performance offers a smart solution with their Lower Heater Return Hose, built from high-temperature silicone that’s made to last. It’s a simple swap that brings real peace of mind, especially if you’ve dealt with leaks or soft, swollen rubber lines before. This kit includes the hose and clamps you need for a clean install, so there’s no guesswork or extra hardware to chase down. Whether you're in the middle of routine maintenance or trying to stay ahead of a potential failure, this upgrade is a no-brainer. It’s a small fix that makes a big difference in keeping your cooling system running strong and leak-free.

Direct Fit Silicone Hose Built For Heavy Use

The Fleece FPE-CUMM-LHCL-1324 Lower Heater Return Hose is designed to replace the factory return line on 2013–2024 Ram 2500 and 3500 trucks with the 6.7L Cummins 24V engine. This hose is a direct-fit replacement for Mopar part numbers 68297774AA, 68213155AD, and 68322483AA, offering an OEM-style fit with upgraded durability. It uses high-temp silicone material that resists heat and pressure far better than standard rubber hoses, making it ideal for hard-working diesel trucks. Fleece includes high-quality hose clamps to ensure a secure and leak-free connection without the need for additional parts or fittings. Installation is straightforward with basic hand tools, and the hose follows factory routing for a clean finish. It’s built to help prevent coolant leaks and long-term wear in one of the most overlooked parts of your cooling system. Whether you’re repairing an active issue or just replacing worn components, this hose is a reliable, long-lasting solution.
