Promaster Steel Helper Springs for 2500 and 3500

$ 495.00

This a traditional steel helper spring for your Dodge Ram Pormaster Van. A great suspension upgrade for RV or heavy cargo Promaster units.  It installs under the factory spring to provide load support. It is a progressive spring that will not engage fully when unloaded, but will engage more as you load the vehicle. It makes contact with the factory springs through the rubber snubbers on the ends which helps create a softer engagement. This progressive isolated style creates less jarring and less rattle than other steel helpers, or add a leaf systems. Never exceed factory GVWR rating for the vehicle.

  • Never Exceed Gross Vehicle Weight Rating
  • Easy installation without disassembling the factory spring pack
  • Made in the USA
  • Works great in combination with Promaster Sway Bar Upgrade
  • Read all manufacturers recommendations and warnings 
  • All warranties are manufacturers warranties
