Description

Two decades of heat cycling plastic components, such as your factory degas tank, will undoubtedly make them brittle and discolored. If your factory plastic degas tank is leaking, you're sick of seeing that ugly yellow plastic, or want to go single big turbo and need more space, then look no further. The Mishimoto aluminum degas tank for 2001-2007 Chevy/GMC 6.6L Duramax (LB7/LLY/LBZ) solves all these problems.----Designed with durability, style, and clearance for big turbos in mind. The fully TIG-welded aluminum construction ensures this will be the last time you need to replace your degas tank, and will spruce up your engine bay in the process. We specifically designed this tank to fit with big single turbos without any trimming or worry about melting your tank. The available micro-wrinkle black powder coated finish is perfect for a clean, stealthy look
