HDNABI has designated STEMCO’s Platinum Performance System Plus™ (PPS+) with Auto-Torq® as the default wheel-end package for all factory-dressed air disc brake axles delivered to North American trailer OEMs.
Highlights
- HDNABI selects STEMCO PPS+ with Auto-Torq as standard wheel-end specification.
- Applies to all dressed air disc axles supplied to Great Dane, Hyundai Translead, Wabash, Fruehauf, and Strick.
- Equipped axles carry an industry-leading 8-year parts and labor warranty.
- Partnership targets improved reliability and uptime for trailer fleets.
Partnership Details
HDNABI, a major supplier of air disc brake axles, now integrates STEMCO’s premium wheel-end system across its complete dressed-axle product line. This specification change affects axles shipped to five leading trailer manufacturers.
The decision aligns with growing adoption of air disc brakes on trailers, where wheel-end performance directly influences braking consistency and component life.
Technical Benefits of PPS+ with Auto-Torq
The Platinum Performance System Plus combines matched STEMCO components designed to reduce installation variables and extend service intervals.
Key elements include:
- Auto-Torq self-adjusting spindle nut for precise, repeatable bearing preload
- Premium STEMCO seals, bearings, and hub caps engineered as an integrated package
- Enhanced corrosion protection and contamination resistance
This systems approach minimizes improper assembly risks common with mixed-component wheel ends.
Warranty and Fleet Impact
Axles equipped with PPS+ and Auto-Torq receive STEMCO’s longest coverage: eight years for both parts and labor on the complete wheel-end system.
Fleet maintenance managers gain predictable costs and reduced roadside failures, supporting higher utilization rates in long-haul and regional operations.
Industry Collaboration
STEMCO and HDNABI field teams are working directly with OEM engineering groups and fleet maintenance personnel to accelerate specification of the enhanced axles in new trailer builds.
The collaboration reinforces component-level integration as air disc brake penetration continues to rise in the North American trailer segment.
