Air disc brake manufacturer HDNABI recently selected Stemco’s Platinum Performance System Plus (PPS+) with Auto-Torq as the standard specification for all dressed air disc axles supplied to trailer OEMs.

HDNABI, which provides dressed air disc axles to leading trailer manufacturers like Great Dane, Hyundai, Wabash, Fruehauf, and Strick, selected the PPS+ system with Auto-Torq to enhance performance, minimize downtime, and provide extended warranty coverage, the companies reported. Stemco’s wheel end technology was chosen for its reliability and integrated-system approach.

“The modern wheel end is a system of codependent pieces, each critical to the overall reliability of your vehicle,” Josh Kucera, Stemco product manager, said in a news release. “Air disc axles continue to raise the bar and are naturally complemented by the PPS+ system of premium Stemco products, ensuring that every component in your wheel end was built to perform to the highest standard.”

Both companies said they see this as a win for fleets.

“With PPS+ and Auto-Torq now standard on HDNABI’s dressed axles, fleets can expect the longest warranty coverage in the industry: eight years, parts and labor, supported by two trusted names in trailer innovation,” said Tre Wright, Stemco national OEM sales manager. “This partnership is a win-win for our customers, and we believe it furthers our commitment to ‘Making the Roadways Safer.’”
