Product Description

The factory rubber upper radiator hose on the L5P Duramax does the job, but it's not exactly a highlight of the engine bay - and rubber hoses degrade over time. This Wehrli pipe replaces it entirely with a fabricated aluminum hard pipe finished in bold WCFab Red, giving your engine bay a cleaner, more finished look while eliminating a wear part.

It bolts in as a direct replacement on stock trucks with no other modifications needed, and installs easily with basic hand tools. Silicone boots and stainless T-bolt clamps are included for a secure connection - just make sure your truck is running the OEM GM radiator, since aftermarket radiators may cause fitment issues.
