Front Brake Rotors | 4WD (1984-89 4Runner)

Front Brake Rotors | 4WD

For 1984–1989 Toyota 4Runner 4WD front disc brake applications

Overview

The DFC OE Replacement Front Brake Rotors are direct-fit cast-iron replacement rotors for 1984–1989 Toyota 4Runner 4WD front brake systems. DFC Premium OE rotors use G3000/G11H18 iron castings, CNC machining, and a non-directional braking surface to match factory-style form, fit, and function while promoting consistent pad bed-in and smooth braking.

Two different front rotor designs were used during the 1st Gen 4Runner production run. The 1984–1985 application uses a larger 302 mm solid rotor, while the 1986–1989 application uses a smaller-diameter but thicker 289 mm vented rotor. These configurations are dimensionally different and are not interchangeable.
