Note: This product may be overkill if you are just doing highway running, but for peace of mind in the heavy stuff, it can't be beaten.

We have had multiple people come in, and others report this failure on the 2020-2022 L5P Duramax. In demanding terrain, mud, snow, water, or otherwise, the coolant lines that run along your frame rail can rub or become entangled in your driveshaft. This can cause severe damage if not caught in time. GM acknowledged this problem in their technical service bulletin, 21-NA-265. We developed this 304 stainless steel kit to give people running their L5P engines peace of mind in extreme conditions.

Part Number: L5P-CHA-A089
