Firestone 3400lb Double Convoluted Air Bag 1/4" Port

Firestone Air Springs allow you to achieve the ultimate low while slamming your custom street rod or truck. Firestone air springs give you the durability of theWorlds Number 1 Air Spring. Firestone has enlisted some of the great leaders in custom suspensions to provide you with the air springs and accessories, as well as their wealth of knowledge and experience to satisfy all your custom suspension needs.

After installing your air helper spring kit make sure you have at least 1/2" of clearance around the entire air spring. A good rule of thumb is to use the thickness of your hand and feel around the entire air spring if you hand comes in contact with an object on the vehicle you may have a problem.
