Adding 8×170 2 inch wheel spacers is one of the most popular modifications that improve the wheel style and performance. For example, pushing the wheels outward increases the track width. A wider track gives the vehicle a more aggressive, muscular look. It also increase the wheel clearance, which allows you to run those cool custom rims without issues.

Generally, it is safe to use 8×170 2 inch wheel spacers. The vehicle’s wheels are actually fastened to the corresponding wheel hub by a clamping force. As long as you torque each lug nut correctly, high-strength spacers won’t break or fail easily. In this post, we’ll examine the best 8×170 2 inch wheel spacers.

How Expert Pick the Best 8×170 2 Inch Wheel Spacers?

Forged Aluminum:
Between steel and aluminum, experts chose forged aluminum 8×170 2 inch wheel spacers. Aluminum alloy rim spacers are lightweight and strong. Due to the material properties, the aluminum rim spacers are good in corrosion resistance and rust-proof.

The best 8×170 wheel spacers should be made of forged 6061-T6/ 7075-T6 aluminum alloy. For those who mainly drive on streets or light off-road, the 6061-T6 wheel spacers are just enough. For those who frequently hit the trails, experts recommend forged 7075-T6 spacers for off-roading use.

Bolt-on Spacers:
It is recommended to use bolt-on type spacers for off-roading use. Bolt-on 2-inch spacers come with integrated wheel studs, so you don’t need to use longer wheel studs. Only if the stud thread is long enough can the studs provide proper clamping force to keep these spacers and wheels balanced.

Wheel Stud Strength:
Many people only focus on the quality of the spacer itself and ignore the strength of the wheel studs. These wheel fasteners are one of the most important parts that keep the wheels secured.

For off-roading adventures, high-strength wheel lugs are necessary. After experts testing, the best 8×170 2 inch wheel spacers should come with ISO grade 12.9 wheel studs and ISO grade 10 lug nuts.

SGS TÜV Test Reports:
How can we know the performance of an 8 lug wheel spacer? The answer is to check the performance test reports. The best 8×170 2 inch wheel spacers should provide proper SGS TÜV test reports.

Why BONOSS 8×170 2 Inch Wheel Spacers Stands Out?

With over 17 years of manufacturing experience, 1800+ drawing updates, BONOSS provides the best 8×170 2 inch wheel spacers. There are several key advantages that make BONOSS forged aluminum wheel spacers a top choice.

1. Top-quality Aluminum Alloy

Considering the strength and rustproof needs, billet aluminum is more suitable for off-roading use. BONOSS forged 8×170 2 inch wheel spacers are made of forged 6061-T6 or 7075-T6 aluminum alloy. The tensile strength is up to 572 MPa (AL7075-T6). Such wheel spacers are strong enough to undertake hard driving.

2. Advanced Hub-centric Design

BONOSS forged 8×170 hub-centric wheel spacers come with better multi-stage hub-centric lips. The hub-centric metal ring is machined to be multi-layers, and the bevels fit the corresponding hub flange, which means zero wheel vibration. This effectively guarantees safety, stability, and reliability in off-roading adventures.

3. Strong Fasteners for Zero Loosen

To safely secure the spacers, BONOSS provides ISO grade 12.9 wheel studs (tensile strength≥1,220 MPa) and ISO grade 10 wheel nuts (proof load≥1,110 MPa). They are meticulously coated with Dacromet. This type of coating gives neutral salt spray resistances exceeding 500 hours. They won’t loosen easily in off-roading conditions.
