Stemco, an Enpro company and maker of heavy-duty components for commercial vehicles, announced the sale of its Trifecta line of pre-adjusted hub assembly products to Webb Wheel Products.
Webb Wheel initially partnered with Stemco to launch Trifecta in 2018. Webb Wheel will continue production of the Trifecta line as it is manufactured today, using Stemco products to ensure efficiencies across the production process.
“Trifecta has proven to be an industry-leading wheel-end solution since its launch, and Stemco is proud of the product we created,” said Drew Coen, senior director of global marketing for Stemco. “We are happy it will continue to be available to our fleet customers via Webb and we look forward to a continued partnership on the seals, bearings, and axle fasteners within the product.”
Trifecta combines Stemco’s high-performance Discover XR seal, Zip-Torq axle fastener, precision bearings, and a spacer optimized for lubricant flow within a Webb hub.
P.J. Caplan, VP of sales and marketing for Webb Wheel Products, said the company plans to leverage the industry knowledge, technical expertise, and product innovation at Webb Wheel to take the program to the next level.
Stemco will continue to honor all Trifecta warranties on previously purchased assemblies. Webb Wheel will begin taking orders for Trifecta on Jan. 8, 2024.
