This upgrade transforms the engine bay appearance while maintaining the reliability of the OEM cooling system.

Key Features:

• CNC-fabricated aluminum construction with gloss black powder coat finish
• 2.0-inch diameter coolant pipe engineered for L5P cooling requirements

This complete kit includes the fabricated aluminum coolant pipe, silicone boots, T-bolt clamps, and powder coating. Designed for use with the OEM GM radiator; aftermarket radiators may cause fitment issues. The L5P Duramax uses larger 2.0-inch diameter coolant plumbing compared to earlier models, and this pipe is specifically shaped to fit 2020 and newer model years. Installation is straightforward on stock trucks with no other modifications necessary.
