As long as you install them properly, it is safe to put quality 4Runner spacers, even if you drive in off-roading adventures. It is a good idea to get genuine brand spacers. Brand manufacturers try to develop the latest and best 4Runner spacers. Many factors determine the quality of 4Runner spacers such as the manufacturing process, the material, and the performance tests. All in all, the reputable brand 4Runner spacers won’t disappoint you.
When installed, the 4Runner spacers become the important parts that connect the wheels and hub assembly. Therefore, you absolutely need strong spacers. As many engineer claims, forged wheel spacers are generally safer and better for off-roading. In this article, we’ll explore the best 4Runner spacers type to help you make a wise decision.
Do 4Runner Spacers Need to Be Hub-centric?
If you would like to use 4Runner spacers off-roading, make sure you get hub-centric spacers. Hub-centric spacers are designed with center rings that fit perfectly the axle and the space inside the center bore of the wheel. This ensures the wheel is properly centered on the spacer, reducing vibrations and preventing potential safety issues.
Avoiding Wheel Vibration:
Hub-centric means that they fit precisely over the car’s axle hub and precisely inside the wheel hub. The hub-centric connection actually holds the weight of the car. A firm hub-spacer-wheel combination reduces the chance of vibration. This ensures a smoother ride and less wear on suspension components.
Easy Installation:
Hub-centric 4Runner spacers are typically easy to install, requiring no special tools or modifications to the vehicle. This accessibility makes them a popular choice among DIY enthusiasts and professional mechanics alike.
What Is the Torque on 4Runner Wheel Nuts?
The REFERENCE torque spec of 4Runner wheel nuts is 83.3 ft-lbs (113 Nm). Remember that this is just a reference to the possible torque. Some specific wheels or applications may need more or less tightening torque. It is always recommended to ask a tire professional for help.
Why BONOSS 4Runner Spacers the Best Choice?
With over 10 years of professional experience, 3000+ actual measurements, 1800+ drawing updates, size precision upgrades, and installation tests, BONOSS makes the best 4Runner spacers. With advanced technology and unmatched quality, BONOSS offers several key advantages that make their spacers a top choice.
1. Effective Active Cooling for More Benefits
Aside from the basic functions, BONOSS forged active cooling 4Runner spacers provide additional advantages. For example, the active cooling technique. Distributed in a petal shape, the cooling grooves allow the external cold air to flow continuously inside the wheel spacer when it rotates.
The flowing air takes away the heat, so it boosts the heat dissipation efficiency of the rotors, reducing brake thermal decay and improving road safety. In addition, the side knurling design eliminates internal stress and enlarges the cooling area, which is good for the active cooling effect.
2. Aerospace-grade Aluminum for Safety
Brands that focus on quality and performance are very strict in raw materials and manufacturing processes. For example, BONOSS forged active cooling 4Runner spacers are made of high-strength 6061-T6 and 7075-T6 aluminum alloy materials. The ultimate tensile strength results of these two aluminum alloys:
- Forged 6061-T6 spacers: 42000-45000 psi (300-310 MPa);
- Forged 7075-T6 spacers: 74000-78000 psi (510-572 MPa).
3. Optimized Hub-centric Design for Stability
BONOSS forged active cooling 4Runner spacers come with multi-stage hub-centric rings. The hub-centric metal ring is machined to multi-layers, and the bevels fit for the corresponding hub flange, which eliminates any possible gaps. This reduces the chances of vibrations.
