Detailed Description

DFC Geoperformance Rotor - Drilled and Slotted 830-48045R is a rear right disc brake rotor engineered for vehicles that use a 6-lug, 127 mm bolt pattern and a vented rear rotor setup. The directional slotted X drilled braking surface is paired with a 325 mm diameter and 85 mm overall height, making it a direct-spec replacement for applications such as 2002-2009 Chevrolet Trailblazer rear right, 2002-2009 GMC Envoy rear right, and 2005-2009 Saab 9-7x rear right. It also fits 2003-2008 Isuzu Ascender rear right, 2004-2007 Buick Rainier rear right, 2003-2006 Chevrolet SSR rear right, 2002-2006 Chevrolet Trailblazer EXT rear right, 2002-2006 GMC Envoy XL rear right, 2004-2005 GMC Envoy XUV rear right, 2003-2005 GMC Jimmy rear right, and 2002-2004 Oldsmobile Bravada rear right. This part number, 830-48045R, is built around the listed dimensions to match the original brake package on these vehicles.

What It Helps Address

• Rear brake rotor wear on supported Chevrolet, GMC, Saab, Isuzu, Buick, and Oldsmobile models
• Rotor scoring or uneven braking surface condition
• Brake pulsation related to rotor thickness variation
• Corrosion on exposed rotor and hat surfaces
• Brake fade concerns during repeated stops

Installation Notes and Tips

Confirm rear right position, 6-lug 127 mm bolt circle, 78.7 mm center hole, and 325 mm outside diameter before installation. Verify the rotor matches the vehicle’s rear brake setup and compare discard thickness against the existing part. Because this rotor uses a directional braking surface, install it in the correct orientation for the rear right side. Always inspect pads, caliper condition, and hub surface before completing brake service.

Quality Assurance

Dynamic Friction identifies this rotor with a rust resistant coating and Geospec Silver Grey hat finish for added surface protection. The part is specified with exact dimensional data for direct replacement use on the listed applications, including Chevrolet Trailblazer, GMC Envoy, and Saab 9-7x rear right fitments.
