McALLISTER SPRING LTD., also known by our trademark "MACSPRING", began operations in 1913 as a manufacturer of automotive suspension leaf springs. Today, McAllister manufactures leaf springs, U-Bolts and associated parts for the OEM (Original Equipment) and aftermarket sectors of the transportation industry. While we make a full range of spring products, McAllister specializes in heavy truck applications.

McAllister Spring Ltd. has long been a company dedicated to manufacturing products that are made using quality materials, processing, and workmanship. We take great pride in being able to respond to customer needs by quickly delivering quality parts at a competitive price. Turn around time for standard parts is normally three working days. Custom parts usually require five to ten working days. Emergency 'truck down' one day response is also available at a premium.

The equipment at MACSPRING enables us to shear, cold form, hot form, heat treat, machine, assemble, test and paint leaf springs, bolts, U-bolts and custom parts. The largest leaf spring assembled to date weighed 1500 pounds and was ordered for a large off-highway mining truck.

MACSPRING has implemented a QS 9002 QUALITY assurance system. We are committed to quality and to the continuous improvement necessary to meet the changing needs of our customers.
