Fits: 2001-2005 GM w/ 6.6L Duramax & Allison 1000 Transmission
If you own a 2001-2005 Duramax you probably know that the GM's OE transmission lines leave something to be desired, they're prone to leak and fail. Deviant saw an opening and engineered the Deviant Race Parts (DRP 73421) High Performance 5/8" Transmission Cooler Repair Lines. These lines are industrial grade and are rated at 1500psi, and completely replace the OEM transmission cooler lines and hardware. These transmission lines are so over-built that they can offer a lifetime warranty - you won't find that on a stock replacement.
