Using 4Runner wheel spacers is one of the most accessible and beneficial modifications. By moving the wheels and tires outward, spacers increase the track width. A wider track means more grip in almost every application. Even if you don’t change the OEM tires, the more track width, the better the handling of curves and swerving, and the resistance to rollover.
For 2025 Toyota 4Runner, you can go 1 inch to 2 inches wider per wheel before needing other modifications. Some key benefits of wheel spacers include:
- Improved stability and handling
- Allowable to fit larger tires
- Enhanced appearance with a more muscular look
But what sizes wheel spacers are the best for a Toyota 4Runner? Let’s take a closer look.
Toyota 4Runner Wheel Spacers Before and After
Choosing the best spacer size depends on the style and performance you want for your 4Runner. Here’s a quick pros and cons breakdown of popular sizes:
- 1-inch Spacers:
The Toyota 4Runner 1-inch wheel spacers are a good start for those who want a subtle and beneficial modification. They enhance handling on paved roads and moderate trails. - 1.5-inch Spacers:
If you aim for a bolder, more aggressive stance, 1.5-inch spacers are your best choice. They also allow for larger tires without rubbing. - 2-inch Spacers:
The 2-inch wheel spacers provide the maximized clearance for oversized tires and provide more stability on rough trails. This spacer size is safe for off-roading use. Remember to use a high-quality set.
Bolt Pattern:
Bolt patterns (PCDs) are specifically set by the manufacturer, helping narrow your wheel spacer choices. Double-check the vehicle bolt pattern in your owner’s manual before buying a set.
Who Makes the Highest Quality 4Runner Wheel Spacers?
When selecting the best wheel spacers for Toyota 4Runner, BONOSS excels in safety and performance. With the advanced technology and unmatched quality, BONOSS offers several key advantages that make their spacers a top choice.
1. Useful Active Cooling Function
With the same price as most rim spacers, BONOSS forged active cooling 4Runner wheel spacers provide an active cooling function. Distributed in petal shape, these grooves allow the external cold air to flow continuously inside the wheel spacer when it rotates.
The air takes away the heat to actively dissipate heat for the brakes. Such BONOSS forged active cooling 4Runner 6×139.7 spacers improve the cooling efficiency, reducing brake thermal decay, and improving road safety.
2. Aerospace-grade Aluminum Materials
All BONOSS forged active cooling Toyota 4Runner wheel spacers are made of forged 6061-T6 or 7075-T6 billet aluminum alloy. The tensile strength is up to 572 MPa and the yield strength is up to 503 MPa (as strong as aviation aircraft). High tensile strength gives it strong resistance to being pulled apart, making it resistant to bending and breaking.
3. Full-cone Seat with Zero Loosen
Full-cone seat design provides a larger contact area, more force acreage, and better fitting. This allows the studs and nuts to apply enough clamping force to lock the BONOSS forged active cooling Toyota 4Runner wheel spacers. In that case, the hub-spacer-wheel connection can be fastened firmly, meaning no vibration.
