Cincinnati, OH, January 12, 2011 -HDX Services, LLC, a wholly-owned subsidiary of Datalliance®, today announced two new distributors signed up to use the HDX SiMAN service: CRW Parts (Baltimiore, MD) and Universal/Lee Smith Truck Parts (Chattanooga, TN). HDX SiMAN is a service that provides a single sign-on solution which allows distributors to easily access and utilize extranet sites for all heavy duty manufacturers.

"The addition of both CRW Parts and Universal/Lee Smith should help us get more traction going into the HDAW show in Las Vegas. Many manufacturers have sites that are very useful to distributors, but are not being used. HDX SiMAN helps both the distributor and the manufacturer actually realize the benefits of extranet/on-line tools, " explained Edward Kuo, Executive Director of HDX Services.

Leading HD distributors currently using HDX SiMAN also include CATCO, CBS Parts, CW Carter/Westpac, DeCarolis Truck, Fleet Brake, Fleet Services, Ft. Garry Industries, Inland Truck Parts, Midwest Wheel Companies, Mutual Wheel, Point Spring and Driveshaft, and Stone Truck Parts. Existing manufacturers participating in the HDX SiMAN service include Heavy Duty industry leaders such as ArvinMeritor, Bendix, Federal Mogul, Gates, Goodyear, Haldex, SKF, and Tectran.

Manufacturer extranets allow distributor users to retrieve their specific account information, including negotiated pricing, product availability and order status. HDX SiMAN offers these distributor users a menu from a single sign-on process to access multiple manufacturer sites. This service helps users access the information they need and answer their questions easily and efficiently. HDX SiMAN also offers better security of account information by managing and communicating personnel changes such as new hires, transfers and terminations directly to suppliers.
