ConMet celebrates three decades of transformative impact on the heavy-duty trucking industry with its revolutionary PreSet® wheel end technology. Launched in 1995, the PreSet family of hubs redefined wheel end assembly, enhancing safety, reliability, and efficiency for Class 8 trucks. Over 40 million PreSet and PreSet Plus hubs have been installed, covering an estimated 31 trillion miles on the road—a testament to their quality and endurance.
Key Highlights:
- Revolutionary Design: PreSet hubs eliminated the complexities of manual wheel end assembly by introducing pre-assembled units, enhancing safety and reliability.
- Advanced Features: The PreSet Plus® hub, launched in 2011, included innovations like an integrated spindle nut and hardened spacers for optimal performance.
- OEM and Aftermarket Benefits: Streamlined manufacturing for OEMs and reduced service complexity for the aftermarket with versatile hub solutions for all axle positions.
- Unmatched Durability: Vertically integrated design ensures superior precision, durability, and quality across all PreSet and PreSet Plus components.
From PreSet to PreSet Plus®
ConMet revolutionized wheel end assembly in 1995 with the launch of PreSet, the first pre-assembled wheel end. By combining all components into a pre-adjusted unit, PreSet simplified installation for OEMs, eliminated guesswork, and enhanced safety. Building on this success, ConMet introduced the PreSet Plus hub in 2011, featuring advanced elements such as an integrated spindle nut and hardened spacers for sustained clamp load and improved durability.
Brian Rieger, ConMet’s Vice President of Sales, remarked, “PreSet Plus represented a significant advancement in wheel end technology…ensuring safer, more efficient operations for our customers.”
OEM and Aftermarket Advantages
For OEMs, PreSet and PreSet Plus hubs offer a pre-assembled, line-sequenced solution, accelerating production timelines and maintaining high-quality standards. Their robust design minimizes the risk of contamination and damage during assembly.
In the aftermarket, these hubs simplify replacement processes, reducing downtime and total cost of ownership for fleets. Available in various configurations, they meet diverse vehicle needs with proven reliability.
Vertically Integrated Excellence
ConMet’s vertical integration ensures compatibility and quality in every component, from hub castings to seals. Precision manufacturing guarantees consistent performance, minimizing failures and enhancing longevity. Bryan Williams, ConMet’s Senior VP of Engineering, stated, “We remain dedicated to shaping the future of wheel end technology with the same passion and innovation that brought us to this point.”
Celebrating 30 Years
ConMet is commemorating this milestone at HDAW 2025 and TMC’s Annual Meeting, showcasing PreSet’s history and advancements through interactive exhibits. For more information, visit conmet.com/preset.
