Overview
The Baer Brakes 31326-020 is a set of two front Claw performance rotors for the 2003–2009 Toyota 4Runner and the 2003–2009 Lexus GX470 with 4WD, where the vehicle has 13.3 inch front rotors. The listed 4Runner entries include RWD and 4WD drive, and the GX470 entry is 4WD. They are direct replacement vented rotors with a slotted and cross-drilled face.
Slots and drilled holes let gases and dust escape from between pad and rotor, supporting a more consistent pedal feel and less brake fade. Each rotor is one-piece full cast iron with a zinc-plated finish. At 337.82 outside diameter, the rotor is larger than many front rotors, so measure your existing rotor before ordering.
Key features
- Slotted and cross-drilled friction surface that moves gases and dust away from the pad
- Enhanced vane structure that Baer says helps cooling and durability
- Premium direct replacement design, mill balanced
- Chamfered cross-drilled holes that Baer says resist stress cracking
- Zinc-plated finish that Baer describes as bright behind open-center wheels
Clearance and larger front rotors
Larger diameter rotors change more than stopping force. A bigger rotor can reduce wheel clearance, so check the caliper bracket, brake hose routing and wheel inner barrel after installation. Rotor size also changes pedal effort, so a different pedal feel after fitting is normal for a short period while the pads bed in.
On a body-on-frame SUV, front rotors are exposed to road debris and water. Check the splash shield for damage and make sure the dust shield does not touch the rotor. Off-road use with heavy loads and frequent braking on long descents produces heat that tests the rotor’s vent passages.
- Confirm caliper bracket clearance after fitting
- Check the splash shield for contact with the rotor
- Re-check lug nut torque after the first drive

Vehicle fitment
It fits the 2003–2009 Toyota 4Runner with RWD or 4WD drive and the 2003–2009 Lexus GX470 with 4WD drive, both with 13.3 inch front rotors.
The list does not cover 4Runner or GX470 models from 2010 onward, or vehicles with a different front rotor size. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The brake surface is directional, so check the rotation marking on each rotor and fit the pair to match. Because the rotor is 337.82 in outside diameter, confirm clearance under the wheel before installation. Bed in new pads as the pad maker directs after the rotors are fitted.
What’s included
The set contains two front rotors, sold as a pair.
Not included: brake pads, which are separate parts.
