About SI Valves
In 1982 a small group of industry professionals with extensive valve train experience got together and formed SI Valves. Their objective was to build a company that directly served engine builders and had the flexibility to meet their needs in product requirements while providing true "one stop shopping" for valves and all types of valve train components.
The company has grown over the years to expand its selection of engine valves to encompass everything from Acuras to Yamahas along with an extensive list of applications in between. SI also manufactures valves to customer specifications in large production runs or smaller quantities.
SI's VTM (Valve Train Manufacturing) division can point to a nearly 40 year background making premium quality bronze valve guides and valve train components. VTM is a supplier to industry-leading aftermarket cylinder head manufacturers and rebuilders.
With a sales and technical staff that's well versed in Muscle Cars, Hot Rods, Sport Compacts and the like, SI stands ready to be your "go to" source for valves and valve train components.
