Our Story

In 1953, James Tennant Sr., started Piston Ring Service & Supply as a two-man Machine Shop in central Winnipeg. Throughout its history, Piston Ring has led a constantly evolving and aggressive attitude to change.

Piston Ring is currently owned and operated by Jim Tennant and Trevor Tennant (James Sr.’s son and grandson), and continue on with their third generation, Melissa Tennant & Meredith Thoendel working at Piston Ring.

Our Winnipeg based company employs over 550 full and part time people and utilizes in excess of 400,000 square feet of distribution and retail space, carrying large inventories, systems and support for our customers.

Expansion and acquisitions has resulted in our present day ownership of 25 corporate Piston Ring/Auto Value Parts stores and 16 associate stores in Manitoba, Saskatchewan, and Northwestern Ontario. This growth has kept Piston Ring as one of the leading automotive aftermarket companies in its trading area.
