DuraGo BR5111 Disc Brake Rotor - Front

DuraGo BR5111 Front Vented Brake Rotor

The DuraGo BR5111 is a front disc brake rotor built for Jeep CJ applications that call for a 5-lug, vented, conventional rotor design. It uses cast iron construction and non-directional brake surface machining to support consistent pad contact on compatible Jeep CJ5, CJ7, and Scrambler front brake setups.

Key Features

• Cast iron, full cast construction for a traditional OE-style rotor build
• Vented rotor design for front brake applications
• Non-directional brake surface for straightforward pad bedding
• Outside diameter: 11.75 in. (298.5 mm)
• Nominal thickness: 0.87 in. (22.2 mm); discard thickness: 0.81 in. (20.7 mm)
• 5 mounting bolt holes with 5.5 in. bolt circle diameter
• Center hole diameter: 3.76 in. (95.4 mm)
• Conventional rotor design with no cross-drilling or slots

Detailed Description

DuraGo BR5111 is a front brake rotor for Jeep CJ5, CJ7, and Scrambler models that use the specified vented rotor configuration. The cast iron, full cast design provides the mass and structure expected in a conventional replacement rotor, while the non-directional surface helps simplify service during brake pad replacement. This rotor measures 11.75 inches in outside diameter and 2.19 inches in overall height, with a 5-lug pattern and 139.7 mm bolt circle.

DuraGo has more than 45 years of aftermarket manufacturing experience, and its brake drum and rotor program is built around catalog accuracy and fit, form, and function requirements from ISO-certified factories. The BR5111 part number is also referenced in the aftermarket under cross-reference numbers such as Anchor 3552 and Hayden 5110 for the same application.
