Whether you're towing the family camper or heading to the job site, your Duramax is built to handle tough tasks. However, the factory radiator hoses on the L5P Duramax (2017-2019) are made from a mix of molded rubber and plastic, materials that can degrade over time. After countless heat cycles, long hours of idling, and thousands of high-stress miles, these hoses can harden, crack, or develop leaks.
That’s why Rudy's developed this premium silicone coolant hose kit for your 2017-2019 6.6L L5P Duramax. Designed for durability, these hoses are crafted with five layers of silicone reinforced with heat-resistant fibers, paired with all-aluminum hose junctions to replace the weaker stock plastic connectors. This ensures superior heat resistance, pressure tolerance, and reliability even in the harshest environments.
To make installation as straightforward as possible, the kit includes stainless-steel worm gear clamps and a replacement O-ring for the lower hose quick-disconnect fitting. With this comprehensive kit, you’ll have everything needed for a leak-free and hassle-free installation.
