Sioux City-based locations increases Arnold’s inventory regionally and expands engine kit offerings nationally with online retailing
Spencer, Iowa—Arnold Motor Supply recently purchased Sioux City, Iowa-based Motor Parts Central and its sister company, Northern Auto Parts. The purchase will allow the company to expand its inventory and distribution in the region.

“The move from our old location in Sioux City to the Motor Parts Central building increases our retail and distribution space by 130,000 square feet,” said Eric Johnson, president and managing partner for Arnold Motor Supply. “The Sioux City location will now serve as a distribution hub for our surrounding parts stores.”
Northern Auto Parts will continue to operate within the same building and is a different type of expansion for the company. Northern is a national online retailer (northernautoparts.com), specializing in engine rebuild kits and engine parts from brands such as ARP, Edelbrock, Holley, Melling and Silvolite.
“For years we’ve provided engine rebuilding and restoration through our machine shops so adding the expertise of the Northern Auto Parts team is a great addition for our customers,” Johnson said.
