Understanding 2 Wheel Spacers for 8x170 Bolt Patterns
When considering modifications for your truck or SUV with an 8x170 bolt pattern, 2 wheel spacers offer a straightforward way to achieve a more aggressive stance or correct wheel offset issues. These devices are installed between the wheel hub and the wheel itself, effectively widening the vehicle's track width by two inches. The primary function is to push wheels outward, which can prevent tire rubbing on suspension components or fender liners, especially when upgrading to larger tires.
- Widen vehicle track width by 2 inches.
- Improve tire clearance for larger wheel/tire combos.
- Correct offset issues for a flush look.
- Designed for specific 8x170 bolt patterns.
The 8x170 bolt pattern is commonly found on many Ford Super Duty trucks, making these spacers a popular choice for owners looking to enhance their vehicle's appearance and functionality. Proper installation is paramount, as incorrect fitment or fastening can lead to serious safety concerns. These spacers can be either hub-centric, featuring a raised lip that matches your vehicle's hub, or lug-centric, relying solely on lug nuts for alignment.
It is imperative to acknowledge that not all wheel spacers are created equal. The quality of materials, manufacturing precision, and the type of spacer (hub-centric vs. lug-centric) significantly influence their performance and safety.
Key Components and Considerations
The core function of wheel spacers lies in their ability to alter wheel offset. By adding thickness, they increase the distance from the wheel mounting surface to the outer edge of the wheel. For an 8x170 vehicle, this translates to wheels sitting further out. This article will delve into the benefits and drawbacks to help you make an informed decision regarding their use.
The material composition, typically aircraft-grade aluminum or steel, determines durability. Machining accuracy is also critical; precisely bored holes and smooth mating surfaces ensure a secure fit and prevent vibrations.
The Advantages: Why Opt for 2 Inch 8x170 Wheel Spacers?
The most compelling reason to install 2 wheel spacers on an 8x170 bolt pattern is the aesthetic enhancement. Widening the stance gives trucks and SUVs a more robust, muscular appearance, filling out the wheel wells and creating a visually appealing, aggressive look that many enthusiasts desire.
Beyond looks, functional benefits are substantial. If you're planning to fit larger, more aggressive off-road tires or simply want to increase tire clearance to prevent rubbing during suspension articulation, spacers are an effective solution. They push the wheel outward, providing valuable millimeters of space between the tire and suspension components like control arms or brake calipers. This is particularly helpful for clearing suspension parts on heavy-duty trucks.
Many owners find that aftermarket wheels, even those with the correct bolt pattern, may have an offset that sits too far inward. Using 2 wheel spacers can correct this, bringing the wheel flush with the fender for a balanced profile, or even allowing for a negative offset appearance without needing entirely new wheels. This ability to fine-tune wheel placement is a primary draw for many truck owners.
Our analysis indicates that for vehicles like the Ford Super Duty, 2 inch 8x170 wheel spacers can significantly improve the vehicle's visual appeal and functional tire fitment.
Secure your spacers properly: Always use high-strength lug nuts specifically designed for spacers, and torque them according to manufacturer specifications. Double-check torque after 50-100 miles of driving.
The precision required for hub-centric 8x170 wheel spacers is paramount for stability, ensuring the wheel is centered on the vehicle's hub, not just the lug studs.
The ability to achieve both aesthetic appeal and practical tire clearance makes 2 wheel spacers a valuable modification for many 8x170 vehicles.
The Drawbacks and Risks of Using Wheel Spacers
Despite their benefits, wheel spacers introduce potential downsides that demand careful consideration. The most significant concern is the increased stress placed on wheel bearings and suspension components. By extending the wheel's leverage point further out, spacers increase the load on these parts, potentially accelerating wear and increasing the risk of premature failure. This is a critical factor for 8 lug wheel spacers on heavy-duty applications.
Another potential issue is vibration. If spacers are not perfectly flat, accurately machined, or installed correctly, they can cause steering wheel shimmy or vibrations that are both annoying and detrimental to other vehicle components. Lug-centric spacers are more prone to this than hub-centric options, especially if the vehicle's original hub bore isn't perfectly centered by the spacer's lug holes.
Furthermore, the extended studs on some spacers, or the need for longer lug nuts to accommodate the spacer thickness, can compromise the thread engagement for your wheels. It is imperative to acknowledge that any modification that extends beyond the original factory fitment carries inherent risks. For instance, if you were considering 5x4 75 wheel spacers on a vehicle not designed for them, the bolt pattern mismatch alone would be a major safety hazard.
You must also consider legality. In some regions, running wheel spacers may be illegal, especially if they cause the tires to extend beyond the fenders, violating local regulations regarding vehicle width or tire coverage. This is a crucial point often overlooked by enthusiasts seeking a particular look.
The most decision-critical phrase here is the potential for accelerated wear on bearings and suspension components. Always weigh this against the aesthetic or clearance gains.
Verify compatibility thoroughly: Before purchasing, confirm the spacer's bolt pattern (8x170), center bore diameter, and thickness are perfectly matched to your specific vehicle's hubs and wheels. Don't assume similar bolt patterns like 8x6 5 are interchangeable.
Verdict: While 2 wheel spacers for an 8x170 bolt pattern can enhance your vehicle's look and tire fitment, they introduce increased stress on suspension components and require meticulous installation. If precise fitment, quality materials, and proper maintenance are prioritized, they can be a valuable upgrade. However, if long-term durability and minimal modification are your goals, you might explore other solutions like wheels with different offsets. Understanding the trade-offs is fundamental for a safe and satisfying modification.
