Founded 1982 in Nashville, Tennessee, S. B. International, Inc.® (SBI®) is a premier supplier of cylinder head components to the automotive, light truck, small- and medium-duty diesel, heavy-duty diesel truck and equipment, agricultural tractor, marine, and industrial engine market worldwide. Our priorities are quality and on-time delivery at a competitive price. Our customers are engine parts distributors, production remanufacturers, and specialty manufacturers and suppliers.

Beginning in 1982 with valve seat inserts, SBI introduced the J-LOY® brand Valve Seat Inserts, a product line focused on heavy duty which evolved to full-line coverage within several years. In 1991, SBI added to its lineup with its E-LOY® brand Engine Valves. With these two major cylinder head component lines, SBI further enhanced product offerings in 1997 by the introductions of valve guides, valve keepers (locks), valve stem seals, valve springs, valve spring rotators, pushrods, rocker components and other related components to offer a full product line for cylinder head remanufacturing. In 2001 SBI acquired Ertel®, Ohio® and Nylen® brand valve guide marketing rights to become the exclusive worldwide aftermarket distributor. To meet the demands of the cylinder head aftermarket, SBI added a full range of injector tubes for most popular heavy-duty applications to its product line in early 2007.

In 2008, SBI and K-Line® Industries signed an agreement making SBI Exclusive Master Distributor of K-Line's renowned Bronze Bullet® brand valve guide liners and guide-liner tooling.
