Some Freightliner air bags can be found with the number 1T15ZR-3 on the rubber. If your air bag has this number, check the diameter of the base. If it’s 9.75″, you’ll want this air bag. If it’s 10.62″, you’ll want part number 280-9780 or 280-9781 shown below. The only difference between those two air bags is the base material.
Firestone offers a complete line of Airide springs, with replacement springs available for virtually every air suspension system on the market today.

A Goodyear sleeve air spring will employ a flexible member without an internally molded bead. The flexmember is attached to the end of the retainers by pinching the material between the ends and the exterior crimp rings which are then adjusted to the proper diameter. There are many applications for Goodyear sleeve style airbag springs. The most common uses are ride springs for passenger cars and truck, isolators and springs for truck cab suspensions and seat springs, as well as many commonly seen industrial applications. 1R12-636 Goodyear Super-Cushion ® Air Spring will give your truck, trailer, or bus a long lasting durability and productivity to the air suspension with years of maintenance free service.
