Used on Peterbilt air suspension setups, this stud fits where the air spring mounts and is threaded for secure contact with brackets. Over time, suspension studs can corrode or weaken due to vibration, load shifts, and exposure — making replacement a necessary step during air spring or bracket servicing. The Automann MPB7546 fits cleanly and helps preserve the vertical alignment of the suspension.
