AIR SPRING STUD KIT (PETERBILT)

This is an air spring stud kit used to securely mount the air spring (air bag) to the suspension on many Peterbilt and Kenworth trucks. The stud is made of durable metal, about 5-1/16 inches long, and features 1/2-13 threads on one end and 1/2-20 threads on the other, allowing it to bolt into the suspension frame and the air spring base. When an air spring is replaced or a stud becomes worn, corroded, or stripped, this kit provides the necessary threaded fastener and compatible hardware to ensure a tight, leak-free connection on Air Trac, Air Leaf, or AirGlide systems.
