Product Line Details

The DFC Brake Rotor - Drilled and Slotted - Silver line focuses on rotor construction that combines a slotted and drilled braking surface with corrosion-resistant finishing. For Hummer H1 owners, this DFC rotor line supports consistent brake service on heavy-duty front right and rear right positions where heat control and rotor durability matter.

Detailed Description

Built by Dynamite Friction, this disc brake rotor is specified for 2002-2004 Hummer H1 models in front right and rear right positions. The rotor uses a directional slotted X drilled surface, vented construction, and a 34.6 mm overall height to match the listed brake package dimensions. The 6-lug pattern, 110 mm bolt circle, and 10.6 mm stud/lug hole diameter align with the confirmed vehicle fitment. Part number 631-44000R is a direct replacement choice for owners servicing the braking system on a Hummer H1 with 10,800 lb GVW requirements.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Rotor Helps Address

• Brake pulsation caused by worn or uneven rotor surfaces
• Reduced braking consistency from heat buildup in heavy-duty use
• Corrosion on exposed rotor surfaces and hat areas
• Rotor replacement needs on 2002-2004 Hummer H1 front right or rear right positions
• Fitment issues tied to incorrect diameter, bolt pattern, or center bore

Installation Notes and Tips

Verify rotor dimensions, bolt circle diameter, center hole diameter, and directional orientation before installation. Confirm the vehicle is a 2002-2004 Hummer H1 with the listed 10,800 lb GVW application and match the rotor to the correct front right or rear right position. Inspect pads, calipers, and hub surfaces during service to ensure the new rotor seats evenly and operates within specification.

Quality Assurance

Dynamite Friction supplies this rotor with a rust-resistant coating and zinc silver hat finish to support corrosion protection in service. The part is built to the listed dimensional specifications for the confirmed Hummer H1 applications.
