Wilson Sporting Goods, which operated one of the world's largest golf equipment plants in Hagen's home of Michigan, bought Hagen's line in 1944 and added him to its advisory board. Wilson used Hagen's name in the Haig Ultra, Ultradyne and Ultradyne II model clubs. Wilson later named a street in Grand Rapids in his honor, and Hagen remained on contract with Wilson until his death in 1969.
Dick's Sporting Goods bought the rights to Hagen golf equipment, and sells a new line of Hagen clubs exclusively in its stores and its Golf Galaxy shops. The clubs are made by Nicklaus Golf
