For many off-roading enthusiasts, the 4Runner wheel spacers provide a bunch of benefits. By pushing the wheels outward, they increase the vehicle’s track width. A wider track provides better handling and cooler wheel style. It is true that proper-size wheel spacers don’t subject your tires to additional wear and tear. So, what size spacers are the best and safest?
For an OEM wheel setup, it is recommended to use 25mm to 35mm wheel spacers on all four tires. By moving the wheels and tires further out from the suspension, these 4Runner wheel spacers help prevent the tire from hitting the fenders, aftermarket coilovers, brakes, or any other suspension parts.
Different Sizes 4Runner Wheel Spacers Before and After
There are various Toyota 4Runner wheel spacers for sale on the market. Here is a brief introduction of the pros and cons of each spacer size:
1/2-inch Wheel Spacers:
If you need extra wheel clearance to clear larger brake calipers but don’t want to push the wheels out too much. Then the 1/2-inch wheel spacers are the perfect options. But you may need longer wheel studs for a proper lug nut engagement.
1-inch Wheel Spacers:
If you never use wheel spacers, then 1-inch spacers are a good start. 1-inch wheel spacers start to deliver noticeable stance changes and improved stability. They’re good if you’re looking for a modest adjustment.
1.25-inch Wheel Spacers:
If you keep OEM wheels and tires, then 1.25-inch wheel spacers are the best option to achieve a perfect flush stance. They offer a noticeable stance difference and help in accommodating wider AT tires.
1.5-inch Wheel Spacers:
1.5-inch spacers will make your Toyota 4Runner stance look more powerful, which also improves the stability on uneven surfaces.
2-inch Wheel Spacers:
2-inch wheel spacers make your vehicle look even more aggressive and rugged. They also enhance the grip and control when navigating challenging terrain.
3-inch Wheel Spacers:
For those who would like to add lift kits while keeping the stock wheels, using 3-inch Toyota 4Runner wheel spacers is a good idea. It’s vital to choose high-quality hub-centric spacers.
