Wagner Brake DSX126358E Disc Brake Rotor - Front

Wagner SD Disc Brake Rotor for Front Applications

The Wagner Brake DSX126358E is a front disc brake rotor built for vehicles that see frequent stops and heavier-duty service. It uses cast iron construction, a vented design, and a rust-resistant coating to support consistent braking performance on applications such as the Cadillac Escalade, Chevrolet Tahoe, and GMC Yukon.

Key Features

• Cast iron, full cast rotor construction
• Vented rotor design for heat management
• Rust resistant coating for added surface protection
• Smooth, directional brake surface
• 12.992 in. outside diameter and 1.181 in. nominal thickness
• 6-lug rotor configuration
• Front position fitment

Product Details

Wagner Brake DSX126358E is engineered as a disc brake rotor for front axle use on a wide range of GM trucks, SUVs, and vans. The rotor’s metallurgy and vented construction are intended to handle repeated braking cycles and elevated heat, which is important for fleet vehicles, delivery vans, municipal units, and emergency-service platforms. The directional surface and smooth finish support stable pad contact, while the rust-resistant coating helps protect non-friction surfaces during normal service. This rotor is also referenced by part number DSX126358E for catalog and search purposes.

Compatible With 2005-2013 Chevrolet Silverado 1500, front; 2007-2014 Chevrolet Tahoe, front; 2007-2014 GMC Yukon, front; and 2013-2019 Cadillac XTS, front. Additional fitment includes Chevrolet Suburban 1500, Avalanche, Express 1500, Express 3500, Silverado 1500 Classic, Cadillac Escalade, Escalade ESV, Escalade EXT, GMC Sierra 1500, Sierra 1500 Classic, Sierra 2500 HD, Savana 1500, Savana 3500, and Yukon XL 1500 in listed front applications.

This part cross-references Raybestos Brakes (e.g., 580279, 580279FZN) for the same application.

Common Issues This Rotor Can Address

• Brake pulsation from worn or heat-affected front rotors
• Reduced stopping consistency during repeated stop-and-go driving
• Surface corrosion on exposed rotor areas
• Brake noise caused by uneven rotor wear
• Heat buildup during towing, delivery, or fleet use

Installation Notes and Tips

Verify rotor diameter, thickness, lug count, and front-position fitment before installation. Inspect pads, calipers, and hub surfaces for wear or contamination, and clean the hub face to help prevent runout-related brake vibration. Because this rotor uses a directional brake surface, confirm correct orientation during installation. Always follow the vehicle manufacturer’s service procedure and torque specifications.

Quality Assurance

Wagner Brake designs SD rotors with metallurgy and heat-management characteristics suited to demanding braking environments. The DSX126358E is built as a cast iron, vented front rotor with rust-resistant coating for dependable service in heavy-use applications.
