Upgrading 5th Gen 4Runner with wheel spacers are safe and useful. By moving the wheels and tires further out from the suspension, wheel spacers help prevent the tire from hitting the fenders or any other suspension parts. This also makes your car look rugged, powerful, and muscular. Such a vehicle will surely turn some heads.
Additionally, installing 4Runner wheel spacers provides many advantages for off-road use, including better stability and rollover resistance. Since the wheel spacers increase the track width, your car performs better in crossing obstacles. One of the most frequently asked questions is: What sizes 4Runner wheel spacers are best? In this post, we’ll examine the safe sizes for driving.

5th Gen 4Runner with Wheel Spacers Sizes Before and After
The sizes of 4Runner wheel spacers can range from 1-inch to 2-inch. Let’s break down the pros and cons of these sizes:
- 1-inch wheel spacers provide a noticeable improvement in the car’s aesthetics and also improve handling by widening the track.
- 1.5-inch wheel spacers are more popular for enthusiasts who want to push their wheels further out from the suspension for a more aggressive stance.
- 2-inch wheel spacers are particularly useful when running larger wheels and tires. They are helpful in improving the stability in high-performance and off-road conditions.
What’s the Bolt Pattern for 5th Gen 4Runner Wheel Spacers?
To ensure a safe fit, the spacer bolt pattern must be the same as the vehicle lug pattern. Double-check the vehicle bolt pattern in your owner’s manual before buying a set.
- 5th Gen 4Runner (2025-2026): PCD=6×139.7mm, CB=95mm, Thread=M14x1.5mm.
- 1st-4th Gen 4Runner (1995-2024): PCD=6×139.7mm, CB=106mm, Thread=M12x1.5mm.
Correct Offset: Wheel spacers reduce the offset. Example: if your stock 4Runner wheel offset is +55mm, then a 1.5-inch spacer will make the final offset +17mm.

Here are several key advantages that make BONOSS spacers a top choice.
1. Active Cooling for Better Driving
BONOSS forged active cooling 4Runner with wheel spacers come with heat dissipation grooves. The heat dissipation grooves allow the external cold air to flow continuously inside the wheel spacer. The air takes away the heat, actively dissipating heat for the braking system. If you pursue better performance, these BONOSS forged wheel spacers are well worth the investment.
2. Hub-centric Design for Enhanced Safety
Make sure your wheel spacers are hub-centric. BONOSS forged active cooling 4Runner wheel spacers are designed with a multi-stage hub-centric lip which is piloted by the center bore of the vehicle hub. They are CNC machining, precision at 0.02mm, which makes the multi-stage hub-centric lip more accurate, perfectly fits the wheel hub. This is effective in reducing the chances of vibrations.
3. Disassembly Grooves for Easier Removal
BONOSS forged 4Runner 6×139.7 spacers are finished with disassembly grooves. The disassembly grooves leave a limited clearance between the brake rotor and spacer. When removing the spacer, place a screwdriver into the notch and then apply force at an angle, you can separate the spacer from the axle hub quickly and efficiently. This is extremely good for protecting the wheel hub.
