About SBI Engine Parts (S.B. International)
Founded in 1982 in Nashville, Tennessee, S.B. International, Inc.® — better known as SBI® — has built its reputation as a premier supplier of cylinder head components in the automotive aftermarket, earning recognition for product quality, availability, and outstanding customer and technical service. For engine builders, machine shops, and production rebuilders, the SBI name carries real weight on the shop floor.
SBI’s coverage spans automotive, light truck, heavy-duty truck and equipment, agricultural, marine, and industrial engines — making it one of the few aftermarket brands capable of serving such a broad range of applications under a single catalog. Whether you’re rebuilding a small-block muscle car engine, a high-mileage diesel pickup, a farm tractor, or a marine inboard, SBI offers components engineered for that specific application.
A Legacy Built on Cylinder Head Expertise
SBI got its start in 1982 by introducing the J-LOY® brand Valve Seat Inserts, a product line initially focused on heavy-duty applications that quickly evolved to full-line coverage. This foundational product — the engine valve seat insert — remains one of SBI’s most recognized offerings, and the depth of their application coverage in this category is exceptional.
In 1991 SBI expanded with its E-LOY® brand Engine Valves, and by 1997 had introduced a complete product line for cylinder head remanufacturing — including valve guides, valve keepers, valve stem seals, valve springs, valve spring rotators, pushrods, and rocker components. This comprehensive approach means technicians can source virtually every cylinder head component from a single trusted supplier.
Today, SBI’s full product range encompasses valve seat inserts, engine valves, valve guides, valve stem seals, valve springs, retainers, keepers, lifters, rocker arm components, pushrods, injector tubes, head saver shims, heat tabs, and torque-to-yield head bolts. That breadth of inventory — backed by decades of application engineering — is what sets SBI apart in the rebuilding market.
Expanding Into Performance with Precision Engine Parts
In 2024, SBI completed the acquisition of Precision Engine Parts (PEP), broadening its existing product categories to include bronze valve guides, performance valves, valve springs, valve spring retainers, valve spring shims, chromoly pushrods, pushrod guide plates, and transmission flexplates. As part of this integration, SBI brought bronze guide manufacturing to its Nashville, Tennessee facility, underscoring the company’s commitment to quality and American manufacturing.
Valvetrain Components You Can Count On
When it comes to critical moving parts inside the engine, SBI’s engine valve lifters and engine rocker arms are engineered with the same exacting standards as their flagship valve seat and valve product lines. SBI valvetrain components are designed for reliable operation in both stock replacement and performance engines, with a focus on consistent quality, proper fitment, and broad application coverage — making them a go-to choice for engine rebuilds where precision matters.
Each SBI part number has a corresponding high-resolution color photograph for visual reference, along with all specifications, OEM and aftermarket interchanges, and a buyer’s guide function that lists all applications in which a given SBI part number can be used — making it easier than ever to confirm you’re ordering the right part for your build. For those working on connecting rod applications, SBI also offers engine connecting rods as part of their expanded Precision Engine Parts lineup.
