Promaster Sway Bar for 1500, 2500 and 3500

We have two sway bars styles available for your fullsized Promaster van. We have a Roadmaster bar that is fitted from 2019 to 2023, that is a 1.25 inch diameter direct fit sway bar. This will replace the factor rear sway bar.  We also have available a Helwig 1 1/8th inch diameter bar that is fitted from 2014 to 2021. This unique system has 3 different adjustments from soft to firm depending on your driving habits and situation. It is recommended to start at the softest setting, test drive and become familiar with the new handling characteristics before adjusting to the firmer settings. This bar will fit vans that came without a rear sway bar. These are both excellent suspension upgrades for heavy cargo vans, Travato, Trend, RV, or any Promaster owner who wants less sway. A heavy duty sway bar stiffens the roll rate of the vehicle for better handling in both unloaded and tow/haul conditions.  Both are made from heat treated, chromoly steel for long lasting performance.
