Hellwig 16-21 Ford F-250 Helper Spring Kit w/ Factory Contact Overload Springs - 2 Additional Leaves

Add assistance to your factory overload springs with Hellwig's Contact Helper Springs. Get help sooner with the contact helper, as the vehicle is loaded the Hellwig contact helper spring connects with the factory contact pads sooner providing better support and less sag for heavy loads. When in contact, the extra Hellwig leaves stiffen the overload springs decreasing the sag of the vehicle in a loaded condition. Hellwig contact overload assist springs mount directly to the factory contact springs for easy install and better load support to increase the truck's level-load carrying capacity. In normal use, they leave performance unchanged.This Part Fits: Year Make Model Submodel 2016-2023 Ford F-250 Super Duty King Ranch 2016-2023 Ford F-250 Super Duty Lariat 2018-2023 Ford F-250 Super Duty Limited 2016-2023 Ford F-250 Super Duty Platinum 2016-2023 Ford F-250 Super Duty XL 2016-2023 Ford F-250 Super Duty XLT 2016-2019,2021-2022 Ford F-350 Super Duty King Ranch 2016-2023
