Stemco has introduced the Trifecta pre-adjusted hub assembly with promises of added safety, performance and confidence.
On the safety front, the zip torq wheel-end fastener features an integrated locking mechanism. The Discover XR seal with GlideTech technology requires no pre-lube and reduces installation force by 50%, minimizing failure modes.
A new spacer design allows lubricant to flow where it’s needed, maximizing spindle, bearing and seal life. It prevents the problem of metal wearing when the wheel travels down the road, which is said to be an issue with traditional spacers.
Original Equipment suppliers will benefit from easier installation, and reduced installation force — only 200 lb-ft compared to 500 lb-ft.
As for confidence, the new offering is backed by both Webb Wheel and Stemco. It has undergone more than 1.4 million miles of field testing, and the individual components that make up the Trifecta have been proven in real world applications.
Stemco is accepting pre-orders now, with availability on tractor positions scheduled for the second quarter of 2018. It will be offered on trailers later this year.
