Built to take the abuse of heavy hauling, the Wagner SevereDuty Rear Disc Brake Pad Set (SX909) is engineered for work trucks that stop hard and often. It installs at the rear axle as a direct-fit replacement for the 2001-2006 Chevrolet Silverado 3500 and GMC Sierra 3500, the 2007 Silverado 3500 Classic and Sierra 3500 Classic, and the 2007-2010 Silverado 3500 HD and Sierra 3500 HD (All engines).
- Semi-metallic, zero-copper formula: carbon-based semi-metallic friction material with Wagner's OE25 zero-copper formulation, engineered in-house for long-lasting braking in the toughest applications.
- SevereDuty design: designed and tested for fleets, police-pursuit use and vehicles run under frequent stopping, gear hauling and heavy loads.
- OE-style features: includes OE-style shims, slots and chamfers, plus a mechanical pad wear sensor and pad shims.
- Validated performance: put through rigorous OE-style on-vehicle testing for braking under extreme heat, frequent stops and heavy loads.
The semi-metallic compound holds up to the high heat generated by heavy loads and repeated stops, suiting it to the 3500-series trucks it fits. Abutment clips are not included, and premium stainless-steel hardware kits are supplied only for select applications — consult the vehicle service information for the correct hardware and whether existing pieces may be reused. This listing is one set, covering the rear axle; replace both sides together for even, balanced braking. If worn rear pads are the cause of noise or reduced braking, this set replaces them.
