Firestone Air Springs Install

Firestone Ride-Ride Air Bag Suspension Kit, model 2299 for Dodge Ram 3500, comes with everything I needed to complete the project under couple hours. Instructions are pretty clear and it is a fairly easy install. It requires no drilling, it does not alter truck’s original suspension and the warranty stays intact.  Please refer to Firestone’s install manual for safety precautions.  Pictures below are showing driver side install. Here are step by step instructions:

1.  Remove the jounce bumper from the truck using 15 mm sucked wrench.

I will be connecting the Firestone Ride-Ride Air Bags to my on-board  2.5 Gallon Viair Air Tank with Firestone 3145 Air-Rite Dual Cab Control Kit in the next project.
