We have both single and dual stabilizer kits available for the 2017-2019 Super Dutys. There's pros and cons for both single and dual stabilizers: duals tend to provide more stability, but usually have lift height requirements. Single stock-replacements don't have lift requirements, but don't provide as much stability with extremely large tires. If you want more specific suggestions, please give us a call directly at 623-434-5277 so we can get more specific about your truck.
