2017-2019 GM Duramax 6.6L L5P Hitches
If you're looking to tow near your 2017-2019 GM 6.6L Duramax L5P's GVWR or GCWR, you're probably going to want to upgrade your truck's hitch. A new Class III hitch is stronger and more reliable than the factory hitches seen on some GM 2500/3500's, and will last longer while delivering a better towing experience compared to the weaker factory hitches. For those constantly towing or hauling heavy loads, an aftermarket hitch can make all the difference. GM Duramax Fitments: 2017, 2018, 2019 GM 6.6L Duramax.
