Built for frequent stops, heavy loads, and hard-working fleets, the Wagner SevereDuty SX827 Front Disc Brake Pad Set (MPN SX827) is a front-axle brake pad set engineered for medium-duty trucks driven in demanding conditions. It installs as a direct-fit replacement for the listed applications, including the 2016-2017 Chevrolet LCF 4500, the Chevrolet and GMC W3500/W4500/W5500 Tiltmaster and Forward cab-overs, and the Isuzu NPR, NPR-HD, NQR, and NRR (All engines) — see the Buyer's Guide tab for the full list of 19 applications.
Wagner SevereDuty pads are designed and tested for fleets, police-pursuit use, and vehicles that face frequent stopping, gear hauling, and heavy loads.
- Semi-metallic friction: carbon-based semi-metallic material developed in-house to deliver long-lasting braking in the toughest applications.
- Zero-copper formulation: features Wagner's OE25 copper-free friction compound.
- OE-style design: includes pad shims and slotted pads; premium stainless-steel hardware kits are included for key applications.
- Tested and validated: OE-style on-vehicle testing for braking performance under extreme heat, frequent stops, and heavy loads.
This set services the front axle; for even, balanced braking it's best to replace the pads on both sides as a matched set. Signs your front pads may need replacing include reduced braking response, squealing, or a grinding noise — diagnose the cause before replacing. Country of origin: United States.
