Description
A hard pipe for the upper hose
This Wehrli pipe replaces the factory rubber upper radiator hose on 2020-2026 L5P trucks with a hard pipe fabricated from aluminum and finished in the powder coat color you pick.
In Wehrli's video, Jason Wehrli explains that the pipe is made from heavier 14 gauge aluminum, so you can tighten the T-bolt clamps firmly to seal the boots without crushing or denting it. It is a looks upgrade, not a power adder.
It fits stock trucks with no other changes and installs with basic hand tools. It is designed around the factory GM radiator; aftermarket radiators may not fit.
Who it's for
2020-2026 L5P owners finishing off a clean engine bay.
