Detailed Description

Beck Arnley 083-2963 is a front brake rotor for Lexus GX470 and Toyota 4Runner applications that call for a vented, 6-lug rotor with a 140 mm bolt pattern.

What This Rotor Helps Address

• Front brake pulsation caused by worn or uneven rotor surfaces
• Brake noise related to rotor wear or surface irregularity
• Reduced braking consistency from rotors below minimum thickness
• Heat buildup in front brake service on vented rotor applications
• Fitment issues when replacing a rotor with the wrong bolt pattern or center bore

Installation Notes and Tips

Verify rotor dimensions, lug count, and bolt pattern before installation. This rotor is listed for front position use only and is not a rear application. Confirm wheel and brake package details on 2003-2009 Toyota 4Runner and 2003-2009 Lexus GX470 models, especially where 17" wheels or premium vented brake specifications are noted. Clean the hub mounting surface and inspect pads, calipers, and hardware condition before completing the brake job.
