Towing and hauling heavy loads with your 2017-2019 GM 6.6L Duramax L5P can put a strain on your truck's overall stability, especially when you find yourself navigating uneven roads or tight corners. Fortunately, we offer a ton of GM 2500HD/3500HD aftermarket sway bar that are specifically engineered to reduce body roll and improve overall handling when your truck is loaded down. Whether installed on the front or rear of your ride, a new sway bar helps keep your truck level and more controlled, making towing trips and long hauls both smoother and safer. For maximum control and comfort, consider upgrading to a new Steering Stabilizer or Control Arms for a complete suspension overhaul.GM Duramax Fitments: 2017, 2018, 2019 GM 6.6L Duramax.Submodel Fitments: WT, Custom, LT, LTZ, High Country, 1LT, 2LT, Pro, SLE, SLT, AT4, Denali.Some exceptions apply, please see individual product pages for specific fitments.
