Engineered for fleets and vehicles worked in demanding conditions, it installs at the front axle of a wide range of commercial trucks — including the 1997-2008 Chevrolet W3500 Tiltmaster and GMC W3500 Forward, the 1997-2009 Isuzu NPR, the 1998-2010 Chevrolet W4500 Tiltmaster and GMC W4500 Forward, and later the 2011-2014 Isuzu Reach and 2016-2017 Chevrolet LCF 3500 (engine: All).
- Long-life friction: Semi-metallic, carbon-based friction material engineered in-house for durable braking in demanding fleet, police-pursuit and heavy-load applications.
- OE-style design: Built with OE-style pad shims and slots for controlled, consistent operation.
- Zero-copper formulation: Features the Wagner OE25 zero-copper friction formula.
- Tested and validated: Rigorous OE-style on-vehicle testing for extreme heat, frequent stopping and heavy loads; premium stainless-steel hardware kits are included for key applications.
