Feature

You can also search for the rubber bellows part number if you don't have the Firestone or the suspension manufacturer numbers. The bellows number can be found directly under the Firestone name on the rubber. A typical reversible sleeve bellows number is 1T15M-6. A typical convoluted bellows number would look like 20F or 313D. Sometimes there is only one air bag that uses a specific bellows number, but most of the time there are several air bags that use the same bellows. You will need to find the air bag that has the same top plate and bottom piston configurations. Be sure to check the maximum and collapsed heights too.

If all else fails, call your local truck or trailer dealer with the VIN number to get their OE part number. We should be able to cross that number to something we stock or can special order.
