Replace leaking or corroded factory heater tubes with this upgraded Fleece Performance kit. Engineered for durability, this kit features corrosion-resistant stainless steel tubes and high-temperature silicone hoses to replace the entire line from the engine block to the firewall. This setup is designed as a direct replacement for 12V Cummins trucks originally equipped with air conditioning.

The kit includes anodized billet aluminum hold-down clamps and a billet standoff to ensure secure mounting. It is compatible with both stock and most aftermarket exhaust manifolds; for aftermarket manifolds, an additional mounting bracket is provided to replace the rear heater line standoff.
