Dually wheel spacers can be safe if installed correctly

Proper installation is crucial to ensuring the safety of your vehicle. It is recommended to follow the instructions provided by the manufacturer, which should enable even novice mechanics or DIYers to safely install wheel spacers. It is also important to use high-quality parts designed to fit properly and withstand the large loads that spacers can experience on the road.

There are several safety precautions to keep in mind when using wheel spacers. Firstly, never use impact wrenches, stack spacers or use multi-piece spacers. Ensure that the inner lug nuts and wheel studs do not protrude past the outer surface of the spacer, and torque the inner lug nuts to the specified tightness, using Loctite. Additionally, it is important to regularly check and tighten the lug nuts on both the spacers and the wheels.

While wheel spacers can improve stability and handling in certain conditions, they also have drawbacks. They can increase strain on axles, steering parts and wheel bearings, leading to faster wear and potential failure. Therefore, it is essential to carefully consider the intended use and potential risks before installing wheel spacers, especially when towing heavy loads or going on long trips.

Spacers can improve stability and reduce leaning on corners

By enlarging the track width, or the distance between the left and right wheels, wheel spacers provide better grip and traction. This improved grip and traction lead to enhanced stability, making your vehicle less prone to leaning on corners. The wider stance of your vehicle also contributes to its resistance to rollover.

Additionally, wheel spacers can increase the offset of the wheels, creating more space for the wheels to turn. This extra space allows the tyres to move further apart, distributing the weight equally among all four wheels. As a result, your vehicle becomes more stable, especially when navigating corners.

The installation of wheel spacers can also improve the appearance of your vehicle. The wheels are pushed outside, giving your vehicle a more robust and muscular look. This enhanced appearance may be appealing to those who value the aesthetics of their car.

It is important to note that while wheel spacers offer these benefits, they also have some potential drawbacks. It is recommended to research and choose quality spacers, as well as ensure regular maintenance and tight fittings to mitigate safety risks.

Safety concerns include strain on axles and wheel bearings

When considering the use of dually wheel spacers with a slide-in camper, safety must be the top priority. A major concern is the additional strain placed on the axles and wheel bearings, which can lead to dangerous situations if not properly addressed.

Dually wheel spacers are designed to fit between the hub and the wheel, creating a wider track width and accommodating larger tires. This modification changes the original dimensions and geometry of the axle and wheel assembly, introducing new stresses and forces.

The increased track width alters the scrub radius, affecting the lateral force on the tires during turning. This change in geometry can place additional strain on the axles, as they now experience greater loads during turns, especially when navigating tight corners or maneuvering in confined spaces.

Moreover, the use of dually wheel spacers affects the effective offset of the wheels, which in turn impacts the wheel bearings. The bearings experience altered loading patterns, with increased pressure on certain areas. This uneven distribution of forces can lead to premature wear, reduced bearing life, and, in severe cases, bearing failure.

To ensure safety and mitigate these concerns, it is crucial to select high-quality dually wheel spacers that are specifically designed and engineered for your vehicle. Reputable manufacturers conduct rigorous testing to ensure their products do not compromise the integrity of the axles and wheel bearings. Proper installation, regular maintenance, and adhering to the recommended load capacities are also essential to minimize safety risks.

Additionally, it is advisable to consult with a professional or a mechanic experienced in such modifications. They can provide valuable insights, ensure correct spacer selection, and guide you on any necessary adjustments or upgrades to safely handle the new configuration. Remember, while dually wheel spacers can provide the desired benefits, prioritizing safety by addressing potential strain on axles and wheel bearings is of utmost importance.

Quality and custom-made spacers are recommended for safety

When it comes to the safety of dually wheel spacers with a slide-in camper, quality and custom-made spacers are highly recommended. While spacers can enhance stability and decrease leaning on corners, it is crucial to prioritize safety.

First and foremost, ensure that you purchase your spacers from a reputable shop that uses top-quality materials. Opt for spacers made from aircraft-grade aluminum, specifically 6061-T6 aluminum, which offers strength, safety, and high resistance to corrosion. Avoid cheap, low-quality adapters, as they may compromise your safety.

Additionally, consider purchasing custom-made spacers from small businesses. They have the expertise to understand your specific needs and can design parts tailored to your vehicle. This personalized approach ensures that your spacers meet your exact specifications, enhancing safety and performance.

Proper installation is another critical factor in ensuring the safety of your vehicle. Follow the installation instructions carefully, whether you're a novice mechanic or a seasoned DIY enthusiast. Take your time and exercise patience during the installation process.

It is also essential to choose the right type of spacers for your vehicle. For instance, if you have a large truck, ensure you select adapters suitable for a heavier haul. Don't cut corners by opting for cheaper, incorrect adapters, as they may lead to disappointing or unsafe results.

Lastly, be cautious when using wheel spacers or adapters. While they have their place in the off-road world, they can increase the strain on various components, such as steering parts and wheel bearings. Regularly check and tighten the lug nuts on both the spacers and wheels to maintain safety.

Wheel spacers can be used to clear brakes and prevent tire rubbing

When pushing the wheels out, you get more inside rim space. As this space increases, you lower the risk of the tire rubbing the suspension or brakes. A performance brake kit comes with larger brake calipers, which require more inside wheel space to fit. At this point, wheel spacers are effective to keep the caliper from rubbing the wheel spokes. This ensures safe driving.

To determine how much inner wheel clearance a wheel has, you need to do some measuring. First, pick one wheel and remove it. Then, place the wheel carefully on the ground (with the inside mounting face up) and prepare two straightedges. Place one straightedge horizontally to the inner mounting surface and the other perpendicular to it. Measure the distance from the inner mounting plate to one wheel spoke—this is your correct inner wheel clearance.

It is recommended that you allow 3mm of space in all directions from the caliper to the wheel spoke. For example, if you have 40mm of space for OEM brake calipers and need at least 49mm of space for aftermarket brake calipers, 12mm wheel spacers will be useful. When using wheel spacers, it is best to use high-quality hub-centric spacers and longer wheel bolts/lugs if necessary.

It is important to confirm that the wider track will allow the tire to clear the fenders in all positions. To do this, turn the steering wheel to the left and right on the spot and check for tire rubbing with the fenders. If there is a rubbing issue, you may need to replace the wheel spacers with a smaller thickness.

While wheel spacers can be effective in preventing tire rubbing, it is important to note that they should be used correctly and safely. Some people view wheel spacers as dangerous and prefer to get a new set of rims with a proper offset instead. It is also recommended to regularly check the torque of the nuts holding the wheel spacers, as well as the lug nuts on the wheels.
