AUTOMANN Center Bolt Hex-Head with Tab Part No: MSC4568

When it comes to maintaining the structural integrity of heavy-duty suspension systems, the MSC4568 Center Bolt (Hex-Head with Tab) stands as a critical component. Intended for use in air-leaf spring and Air Trac assemblies, this bolt is precisely engineered with a ¾-16 thread and 4.25″ length, according to listings. Its hex-head design, combined with the tab, provides secure anchoring and prevents unwanted rotation or loosening under load. Cross-referenced to part numbers such as 03-02583, 302583, SCB-260, SC340414R and others, it supports a wide range of truck suspension applications. Purchased from Wofford Truck Parts, this center bolt offers a robust aftermarket alternative to OEM hardware, helping fleets and owner-operators restore proper spring alignment, reduce suspension noise, and prolong component life.
